DESCRIPTION
       You can query/set/replace/unset options with this command. The name is
       actually the section and the key separated by a dot, and the value will
       be escaped.

       Multiple lines can be added to an option by using the --add option. If
       you want to update or unset an option which can occur on multiple
       lines, a POSIX regexp value_regex needs to be given. Only the existing
       values that match the regexp are updated or unset. If you want to
       handle the lines that do not match the regex, just prepend a single
       exclamation mark in front (see also the section called "EXAMPLES").

       The --type=<type> option instructs git config to ensure that incoming
       and outgoing values are canonicalize-able under the given <type>. If no
       --type=<type> is given, no canonicalization will be performed. Callers
       may unset an existing --type specifier with --no-type.

       When reading, the values are read from the system, global and
       repository local configuration files by default, and options --system,
       --global, --local, --worktree and --file <filename> can be used to tell
       the command to read from only that location (see the section called
       "FILES").

       When writing, the new value is written to the repository local
       configuration file by default, and options --system, --global,
       --worktree, --file <filename> can be used to tell the command to write
       to that location (you can say --local but that is the default).

       This command will fail with non-zero status upon error. Some exit codes
       are:

       o   The section or key is invalid (ret=1),

       o   no section or name was provided (ret=2),

       o   the config file is invalid (ret=3),

       o   the config file cannot be written (ret=4),

       o   you try to unset an option which does not exist (ret=5),

       o   you try to unset/set an option for which multiple lines match
           (ret=5), or

       o   you try to use an invalid regexp (ret=6).

       On success, the command returns the exit code 0.

OPTIONS
       --replace-all
           Default behavior is to replace at most one line. This replaces all
           lines matching the key (and optionally the value_regex).

       --add
           Adds a new line to the option without altering any existing values.
           This is the same as providing ^$ as the value_regex in
           --replace-all.

       --get
           Get the value for a given key (optionally filtered by a regex
           matching the value). Returns error code 1 if the key was not found
           and the last value if multiple key values were found.

       --get-all
           Like get, but returns all values for a multi-valued key.

       --get-regexp
           Like --get-all, but interprets the name as a regular expression and
           writes out the key names. Regular expression matching is currently
           case-sensitive and done against a canonicalized version of the key
           in which section and variable names are lowercased, but subsection
           names are not.

       --get-urlmatch name URL
           When given a two-part name section.key, the value for
           section.<url>.key whose <url> part matches the best to the given
           URL is returned (if no such key exists, the value for section.key
           is used as a fallback). When given just the section as name, do so
           for all the keys in the section and list them. Returns error code 1
           if no value is found.

       --global
           For writing options: write to global ~/.gitconfig file rather than
           the repository .git/config, write to $XDG_CONFIG_HOME/git/config
           file if this file exists and the ~/.gitconfig file doesn't.

           For reading options: read only from global ~/.gitconfig and from
           $XDG_CONFIG_HOME/git/config rather than from all available files.

           See also the section called "FILES".

       --system
           For writing options: write to system-wide $(prefix)/etc/gitconfig
           rather than the repository .git/config.

           For reading options: read only from system-wide
           $(prefix)/etc/gitconfig rather than from all available files.

           See also the section called "FILES".

       --local
           For writing options: write to the repository .git/config file. This
           is the default behavior.

           For reading options: read only from the repository .git/config
           rather than from all available files.

           See also the section called "FILES".

       --worktree
           Similar to --local except that .git/config.worktree is read from or
           written to if extensions.worktreeConfig is present. If not it's the
           same as --local.

       -f config-file, --file config-file
           Use the given config file instead of the one specified by
           GIT_CONFIG.

       --blob blob
           Similar to --file but use the given blob instead of a file. E.g.
           you can use master:.gitmodules to read values from the file
           .gitmodules in the master branch. See "SPECIFYING REVISIONS"
           section in gitrevisions(7) for a more complete list of ways to
           spell blob names.

       --remove-section
           Remove the given section from the configuration file.

       --rename-section
           Rename the given section to a new name.

       --unset
           Remove the line matching the key from config file.

       --unset-all
           Remove all lines matching the key from config file.

       -l, --list
           List all variables set in config file, along with their values.

       --type <type>
           git config will ensure that any input or output is valid under the
           given type constraint(s), and will canonicalize outgoing values in
           <type>'s canonical form.

           Valid <type>'s include:

           o   bool: canonicalize values as either "true" or "false".

           o   int: canonicalize values as simple decimal numbers. An optional
               suffix of k, m, or g will cause the value to be multiplied by
               1024, 1048576, or 1073741824 upon input.

           o   bool-or-int: canonicalize according to either bool or int, as
               described above.

           o   path: canonicalize by adding a leading ~ to the value of $HOME
               and ~user to the home directory for the specified user. This
               specifier has no effect when setting the value (but you can use
               git config section.variable ~/ from the command line to let
               your shell do the expansion.)

           o   expiry-date: canonicalize by converting from a fixed or
               relative date-string to a timestamp. This specifier has no
               effect when setting the value.

           o   color: When getting a value, canonicalize by converting to an
               ANSI color escape sequence. When setting a value, a
               sanity-check is performed to ensure that the given value is
               canonicalize-able as an ANSI color, but it is written as-is.

       --bool, --int, --bool-or-int, --path, --expiry-date
           Historical options for selecting a type specifier. Prefer instead
           --type (see above).

       --no-type
           Un-sets the previously set type specifier (if one was previously
           set). This option requests that git config not canonicalize the
           retrieved variable.  --no-type has no effect without --type=<type>
           or --<type>.

       -z, --null
           For all options that output values and/or keys, always end values
           with the null character (instead of a newline). Use newline instead
           as a delimiter between key and value. This allows for secure
           parsing of the output without getting confused e.g. by values that
           contain line breaks.

       --name-only
           Output only the names of config variables for --list or
           --get-regexp.

       --show-origin
           Augment the output of all queried config options with the origin
           type (file, standard input, blob, command line) and the actual
           origin (config file path, ref, or blob id if applicable).

       --show-scope
           Similar to --show-origin in that it augments the output of all
           queried config options with the scope of that value (local, global,
           system, command).

       --get-colorbool name [stdout-is-tty]
           Find the color setting for name (e.g.  color.diff) and output
           "true" or "false".  stdout-is-tty should be either "true" or
           "false", and is taken into account when configuration says "auto".
           If stdout-is-tty is missing, then checks the standard output of the
           command itself, and exits with status 0 if color is to be used, or
           exits with status 1 otherwise. When the color setting for name is
           undefined, the command uses color.ui as fallback.

       --get-color name [default]
           Find the color configured for name (e.g.  color.diff.new) and
           output it as the ANSI color escape sequence to the standard output.
           The optional default parameter is used instead, if there is no
           color configured for name.

           --type=color [--default=<default>] is preferred over --get-color
           (but note that --get-color will omit the trailing newline printed
           by --type=color).

       -e, --edit
           Opens an editor to modify the specified config file; either
           --system, --global, or repository (default).

       --[no-]includes
           Respect include.*  directives in config files when looking up
           values. Defaults to off when a specific file is given (e.g., using
           --file, --global, etc) and on when searching all config files.

       --default <value>
           When using --get, and the requested variable is not found, behave
           as if <value> were the value assigned to the that variable.

CONFIGURATION
       pager.config is only respected when listing configuration, i.e., when
       using --list or any of the --get-* which may return multiple results.
       The default is to use a pager.

FILES
       If not set explicitly with --file, there are four files where git
       config will search for configuration options:

       $(prefix)/etc/gitconfig
           System-wide configuration file.

       $XDG_CONFIG_HOME/git/config
           Second user-specific configuration file. If $XDG_CONFIG_HOME is not
           set or empty, $HOME/.config/git/config will be used. Any
           single-valued variable set in this file will be overwritten by
           whatever is in ~/.gitconfig. It is a good idea not to create this
           file if you sometimes use older versions of Git, as support for
           this file was added fairly recently.

       ~/.gitconfig
           User-specific configuration file. Also called "global"
           configuration file.

       $GIT_DIR/config
           Repository specific configuration file.

       $GIT_DIR/config.worktree
           This is optional and is only searched when
           extensions.worktreeConfig is present in $GIT_DIR/config.

       If no further options are given, all reading options will read all of
       these files that are available. If the global or the system-wide
       configuration file are not available they will be ignored. If the
       repository configuration file is not available or readable, git config
       will exit with a non-zero error code. However, in neither case will an
       error message be issued.

       The files are read in the order given above, with last value found
       taking precedence over values read earlier. When multiple values are
       taken then all values of a key from all files will be used.

       You may override individual configuration parameters when running any
       git command by using the -c option. See git(1) for details.

       All writing options will per default write to the repository specific
       configuration file. Note that this also affects options like
       --replace-all and --unset. git config will only ever change one file at
       a time.

       You can override these rules either by command-line options or by
       environment variables. The --global, --system and --worktree options
       will limit the file used to the global, system-wide or per-worktree
       file respectively. The GIT_CONFIG environment variable has a similar
       effect, but you can specify any filename you want.

ENVIRONMENT
       GIT_CONFIG
           Take the configuration from the given file instead of .git/config.
           Using the "--global" option forces this to ~/.gitconfig. Using the
           "--system" option forces this to $(prefix)/etc/gitconfig.

       GIT_CONFIG_NOSYSTEM
           Whether to skip reading settings from the system-wide
           $(prefix)/etc/gitconfig file. See git(1) for details.

       See also the section called "FILES".

EXAMPLES
       Given a .git/config like this:

           #
           # This is the config file, and
           # a '#' or ';' character indicates
           # a comment
           #

           ; core variables
           [core]
                   ; Don't trust file modes
                   filemode = false

           ; Our diff algorithm
           [diff]
                   external = /usr/local/bin/diff-wrapper
                   renames = true

           ; Proxy settings
           [core]
                   gitproxy=proxy-command for kernel.org
                   gitproxy=default-proxy ; for all the rest

           ; HTTP
           [http]
                   sslVerify
           [http "https://weak.example.com"]
                   sslVerify = false
                   cookieFile = /tmp/cookie.txt

       you can set the filemode to true with

           % git config core.filemode true

       The hypothetical proxy command entries actually have a postfix to
       discern what URL they apply to. Here is how to change the entry for
       kernel.org to "ssh".

           % git config core.gitproxy '"ssh" for kernel.org' 'for kernel.org$'

       This makes sure that only the key/value pair for kernel.org is
       replaced.

       To delete the entry for renames, do

           % git config --unset diff.renames

       If you want to delete an entry for a multivar (like core.gitproxy
       above), you have to provide a regex matching the value of exactly one
       line.

       To query the value for a given key, do

           % git config --get core.filemode

       or

           % git config core.filemode

       or, to query a multivar:

           % git config --get core.gitproxy "for kernel.org$"

       If you want to know all the values for a multivar, do:

           % git config --get-all core.gitproxy

       If you like to live dangerously, you can replace all core.gitproxy by a
       new one with

           % git config --replace-all core.gitproxy ssh

       However, if you really only want to replace the line for the default
       proxy, i.e. the one without a "for ..." postfix, do something like
       this:

           % git config core.gitproxy ssh '! for '

       To actually match only values with an exclamation mark, you have to

           % git config section.key value '[!]'

       To add a new proxy, without altering any of the existing ones, use

           % git config --add core.gitproxy '"proxy-command" for example.com'

       An example to use customized color from the configuration in your
       script:

           #!/bin/sh
           WS=$(git config --get-color color.diff.whitespace "blue reverse")
           RESET=$(git config --get-color "" "reset")
           echo "${WS}your whitespace color or blue reverse${RESET}"

       For URLs in https://weak.example.com, http.sslVerify is set to false,
       while it is set to true for all others:

           % git config --type=bool --get-urlmatch http.sslverify https://good.example.com
           true
           % git config --type=bool --get-urlmatch http.sslverify https://weak.example.com
           false
           % git config --get-urlmatch http https://weak.example.com
           http.cookieFile /tmp/cookie.txt
           http.sslverify false

CONFIGURATION FILE
       The Git configuration file contains a number of variables that affect
       the Git commands' behavior. The files .git/config and optionally
       config.worktree (see the "CONFIGURATION FILE" section of git-
       worktree(1)) in each repository are used to store the configuration for
       that repository, and $HOME/.gitconfig is used to store a per-user
       configuration as fallback values for the .git/config file. The file
       /etc/gitconfig can be used to store a system-wide default
       configuration.

       The configuration variables are used by both the Git plumbing and the
       porcelains. The variables are divided into sections, wherein the fully
       qualified variable name of the variable itself is the last
       dot-separated segment and the section name is everything before the
       last dot. The variable names are case-insensitive, allow only
       alphanumeric characters and -, and must start with an alphabetic
       character. Some variables may appear multiple times; we say then that
       the variable is multivalued.

   Syntax
       The syntax is fairly flexible and permissive; whitespaces are mostly
       ignored. The # and ; characters begin comments to the end of line,
       blank lines are ignored.

       The file consists of sections and variables. A section begins with the
       name of the section in square brackets and continues until the next
       section begins. Section names are case-insensitive. Only alphanumeric
       characters, - and . are allowed in section names. Each variable must
       belong to some section, which means that there must be a section header
       before the first setting of a variable.

       Sections can be further divided into subsections. To begin a subsection
       put its name in double quotes, separated by space from the section
       name, in the section header, like in the example below:

                   [section "subsection"]

       Subsection names are case sensitive and can contain any characters
       except newline and the null byte. Doublequote " and backslash can be
       included by escaping them as \" and \\, respectively. Backslashes
       preceding other characters are dropped when reading; for example, \t is
       read as t and \0 is read as 0 Section headers cannot span multiple
       lines. Variables may belong directly to a section or to a given
       subsection. You can have [section] if you have [section "subsection"],
       but you don't need to.

       There is also a deprecated [section.subsection] syntax. With this
       syntax, the subsection name is converted to lower-case and is also
       compared case sensitively. These subsection names follow the same
       restrictions as section names.

       All the other lines (and the remainder of the line after the section
       header) are recognized as setting variables, in the form name = value
       (or just name, which is a short-hand to say that the variable is the
       boolean "true"). The variable names are case-insensitive, allow only
       alphanumeric characters and -, and must start with an alphabetic
       character.

       A line that defines a value can be continued to the next line by ending
       it with a \; the backquote and the end-of-line are stripped. Leading
       whitespaces after name =, the remainder of the line after the first
       comment character # or ;, and trailing whitespaces of the line are
       discarded unless they are enclosed in double quotes. Internal
       whitespaces within the value are retained verbatim.

       Inside double quotes, double quote " and backslash \ characters must be
       escaped: use \" for " and \\ for \.

       The following escape sequences (beside \" and \\) are recognized: \n
       for newline character (NL), \t for horizontal tabulation (HT, TAB) and
       \b for backspace (BS). Other char escape sequences (including octal
       escape sequences) are invalid.

   Includes
       The include and includeIf sections allow you to include config
       directives from another source. These sections behave identically to
       each other with the exception that includeIf sections may be ignored if
       their condition does not evaluate to true; see "Conditional includes"
       below.

       You can include a config file from another by setting the special
       include.path (or includeIf.*.path) variable to the name of the file to
       be included. The variable takes a pathname as its value, and is subject
       to tilde expansion. These variables can be given multiple times.

       The contents of the included file are inserted immediately, as if they
       had been found at the location of the include directive. If the value
       of the variable is a relative path, the path is considered to be
       relative to the configuration file in which the include directive was
       found. See below for examples.

   Conditional includes
       You can include a config file from another conditionally by setting a
       includeIf.<condition>.path variable to the name of the file to be
       included.

       The condition starts with a keyword followed by a colon and some data
       whose format and meaning depends on the keyword. Supported keywords
       are:

       gitdir
           The data that follows the keyword gitdir: is used as a glob
           pattern. If the location of the .git directory matches the pattern,
           the include condition is met.

           The .git location may be auto-discovered, or come from $GIT_DIR
           environment variable. If the repository is auto discovered via a
           .git file (e.g. from submodules, or a linked worktree), the .git
           location would be the final location where the .git directory is,
           not where the .git file is.

           The pattern can contain standard globbing wildcards and two
           additional ones, **/ and /**, that can match multiple path
           components. Please refer to gitignore(5) for details. For
           convenience:

           o   If the pattern starts with ~/, ~ will be substituted with the
               content of the environment variable HOME.

           o   If the pattern starts with ./, it is replaced with the
               directory containing the current config file.

           o   If the pattern does not start with either ~/, ./ or /, **/ will
               be automatically prepended. For example, the pattern foo/bar
               becomes **/foo/bar and would match /any/path/to/foo/bar.

           o   If the pattern ends with /, ** will be automatically added. For
               example, the pattern foo/ becomes foo/**. In other words, it
               matches "foo" and everything inside, recursively.

       gitdir/i
           This is the same as gitdir except that matching is done
           case-insensitively (e.g. on case-insensitive file systems)

       onbranch
           The data that follows the keyword onbranch: is taken to be a
           pattern with standard globbing wildcards and two additional ones,
           **/ and /**, that can match multiple path components. If we are in
           a worktree where the name of the branch that is currently checked
           out matches the pattern, the include condition is met.

           If the pattern ends with /, ** will be automatically added. For
           example, the pattern foo/ becomes foo/**. In other words, it
           matches all branches that begin with foo/. This is useful if your
           branches are organized hierarchically and you would like to apply a
           configuration to all the branches in that hierarchy.

       A few more notes on matching via gitdir and gitdir/i:

       o   Symlinks in $GIT_DIR are not resolved before matching.

       o   Both the symlink & realpath versions of paths will be matched
           outside of $GIT_DIR. E.g. if ~/git is a symlink to
           /mnt/storage/git, both gitdir:~/git and gitdir:/mnt/storage/git
           will match.

           This was not the case in the initial release of this feature in
           v2.13.0, which only matched the realpath version. Configuration
           that wants to be compatible with the initial release of this
           feature needs to either specify only the realpath version, or both
           versions.

       o   Note that "../" is not special and will match literally, which is
           unlikely what you want.

           [core]
                   ; Don't trust file modes

                   path = foo.inc

   Values
       Values of many variables are treated as a simple string, but there are
       variables that take values of specific types and there are rules as to
       how to spell them.

       boolean
           When a variable is said to take a boolean value, many synonyms are
           accepted for true and false; these are all case-insensitive.

           true
               Boolean true literals are yes, on, true, and 1. Also, a
               variable defined without = <value> is taken as true.

           false
               Boolean false literals are no, off, false, 0 and the empty
               string.

               When converting a value to its canonical form using the
               --type=bool type specifier, git config will ensure that the
               output is "true" or "false" (spelled in lowercase).

       integer
           The value for many variables that specify various sizes can be
           suffixed with k, M,... to mean "scale the number by 1024", "by
           1024x1024", etc.

       color
           The value for a variable that takes a color is a list of colors (at
           most two, one for foreground and one for background) and attributes
           (as many as you want), separated by spaces.

           The basic colors accepted are normal, black, red, green, yellow,
           blue, magenta, cyan and white. The first color given is the
           foreground; the second is the background. All the basic colors
           except normal have a bright variant that can be speficied by
           prefixing the color with bright, like brightred.

           Colors may also be given as numbers between 0 and 255; these use
           ANSI 256-color mode (but note that not all terminals may support
           this). If your terminal supports it, you may also specify 24-bit
           RGB values as hex, like #ff0ab3.

           The accepted attributes are bold, dim, ul, blink, reverse, italic,
           and strike (for crossed-out or "strikethrough" letters). The
           position of any attributes with respect to the colors (before,
           after, or in between), doesn't matter. Specific attributes may be
           turned off by prefixing them with no or no- (e.g., noreverse,
           no-ul, etc).

           An empty color string produces no color effect at all. This can be
           used to avoid coloring specific elements without disabling color
           entirely.

           For git's pre-defined color slots, the attributes are meant to be
           reset at the beginning of each item in the colored output. So
           setting color.decorate.branch to black will paint that branch name
           in a plain black, even if the previous thing on the same output
           line (e.g. opening parenthesis before the list of branch names in
           log --decorate output) is set to be painted with bold or some other
           attribute. However, custom log formats may do more complicated and
           layered coloring, and the negated forms may be useful there.

       pathname
           A variable that takes a pathname value can be given a string that
           begins with "~/" or "~user/", and the usual tilde expansion happens
           to such a string: ~/ is expanded to the value of $HOME, and ~user/
           to the specified user's home directory.

   Variables
       Note that this list is non-comprehensive and not necessarily complete.
       For command-specific variables, you will find a more detailed
       description in the appropriate manual page.

       Other git-related tools may and do use their own variables. When
       inventing new variables for use in your own tool, make sure their names
       do not conflict with those that are used by Git itself and other
       popular tools, and describe them in your documentation.

       advice.*
           These variables control various optional help messages designed to
           aid new users. All advice.*  variables default to true, and you can
           tell Git that you do not need help by setting these to false:

           fetchShowForcedUpdates
               Advice shown when git-fetch(1) takes a long time to calculate
               forced updates after ref updates, or to warn that the check is
               disabled.

           pushUpdateRejected
               Set this variable to false if you want to disable
               pushNonFFCurrent, pushNonFFMatching, pushAlreadyExists,
               pushFetchFirst, and pushNeedsForce simultaneously.

           pushNonFFCurrent
               Advice shown when git-push(1) fails due to a non-fast-forward
               update to the current branch.

           pushNonFFMatching
               Advice shown when you ran git-push(1) and pushed matching refs
               explicitly (i.e. you used :, or specified a refspec that isn't
               your current branch) and it resulted in a non-fast-forward
               error.

           pushAlreadyExists
               Shown when git-push(1) rejects an update that does not qualify
               for fast-forwarding (e.g., a tag.)

           pushFetchFirst
               Shown when git-push(1) rejects an update that tries to
               overwrite a remote ref that points at an object we do not have.

           pushNeedsForce
               Shown when git-push(1) rejects an update that tries to
               overwrite a remote ref that points at an object that is not a
               commit-ish, or make the remote ref point at an object that is
               not a commit-ish.

           pushUnqualifiedRefname
               Shown when git-push(1) gives up trying to guess based on the
               source and destination refs what remote ref namespace the
               source belongs in, but where we can still suggest that the user
               push to either refs/heads/* or refs/tags/* based on the type of
               the source object.

           statusAheadBehind
               Shown when git-status(1) computes the ahead/behind counts for a
               local ref compared to its remote tracking ref, and that
               calculation takes longer than expected. Will not appear if
               status.aheadBehind is false or the option --no-ahead-behind is
               given.

           statusHints
               Show directions on how to proceed from the current state in the
               output of git-status(1), in the template shown when writing
               commit messages in git-commit(1), and in the help message shown
               by git-switch(1) or git-checkout(1) when switching branch.

           statusUoption
               Advise to consider using the -u option to git-status(1) when
               the command takes more than 2 seconds to enumerate untracked
               files.

           commitBeforeMerge
               Advice shown when git-merge(1) refuses to merge to avoid
               overwriting local changes.

           resetQuiet
               Advice to consider using the --quiet option to git-reset(1)
               when the command takes more than 2 seconds to enumerate
               unstaged changes after reset.

           resolveConflict
               Advice shown by various commands when conflicts prevent the
               operation from being performed.

           sequencerInUse
               Advice shown when a sequencer command is already in progress.

           implicitIdentity
               Advice on how to set your identity configuration when your
               information is guessed from the system username and domain
               name.

           detachedHead
               Advice shown when you used git-switch(1) or git-checkout(1) to
               move to the detach HEAD state, to instruct how to create a
               local branch after the fact.

           checkoutAmbiguousRemoteBranchName
               Advice shown when the argument to git-checkout(1) and git-
               switch(1) ambiguously resolves to a remote tracking branch on
               more than one remote in situations where an unambiguous
               argument would have otherwise caused a remote-tracking branch
               to be checked out. See the checkout.defaultRemote configuration
               variable for how to set a given remote to used by default in
               some situations where this advice would be printed.

           amWorkDir
               Advice that shows the location of the patch file when git-am(1)
               fails to apply it.

           rmHints
               In case of failure in the output of git-rm(1), show directions
               on how to proceed from the current state.

               Advice on what to do when you've accidentally added one git
               repo inside of another.

           ignoredHook
               Advice shown if a hook is ignored because the hook is not set
               as executable.

           waitingForEditor
               Print a message to the terminal whenever Git is waiting for
               editor input from the user.

           nestedTag
               Advice shown if a user attempts to recursively tag a tag
               object.

           submoduleAlternateErrorStrategyDie
               Advice shown when a submodule.alternateErrorStrategy option
               configured to "die" causes a fatal error.

           addIgnoredFile
               Advice shown if a user attempts to add an ignored file to the
               index.

           addEmptyPathspec
               Advice shown if a user runs the add command without providing
               the pathspec parameter.

       core.fileMode
           Tells Git if the executable bit of files in the working tree is to
           be honored.

           Some filesystems lose the executable bit when a file that is marked
           as executable is checked out, or checks out a non-executable file
           with executable bit on.  git-clone(1) or git-init(1) probe the
           filesystem to see if it handles the executable bit correctly and
           this variable is automatically set as necessary.

           A repository, however, may be on a filesystem that handles the
           filemode correctly, and this variable is set to true when created,
           but later may be made accessible from another environment that
           loses the filemode (e.g. exporting ext4 via CIFS mount, visiting a
           Cygwin created repository with Git for Windows or Eclipse). In such
           a case it may be necessary to set this variable to false. See git-
           update-index(1).

           The default is true (when core.filemode is not specified in the
           config file).

       core.hideDotFiles
           (Windows-only) If true, mark newly-created directories and files
           whose name starts with a dot as hidden. If dotGitOnly, only the
           .git/ directory is hidden, but no other files starting with a dot.
           The default mode is dotGitOnly.

       core.ignoreCase
           Internal variable which enables various workarounds to enable Git
           to work better on filesystems that are not case sensitive, like
           APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
           finds "makefile" when Git expects "Makefile", Git will assume it is
           really the same file, and continue to remember it as "Makefile".

           The default is false, except git-clone(1) or git-init(1) will probe
           and set core.ignoreCase true if appropriate when the repository is
           created.

           Git relies on the proper configuration of this variable for your
           operating and file system. Modifying this value may result in
           unexpected behavior.

       core.precomposeUnicode
           This option is only used by Mac OS implementation of Git. When
           core.precomposeUnicode=true, Git reverts the unicode decomposition
           of filenames done by Mac OS. This is useful when sharing a
           repository between Mac OS and Linux or Windows. (Git for Windows
           1.7.10 or higher is needed, or Git under cygwin 1.7). When false,
           file names are handled fully transparent by Git, which is backward
           compatible with older versions of Git.

       core.protectHFS
           If set to true, do not allow checkout of paths that would be
           considered equivalent to .git on an HFS+ filesystem. Defaults to
           true on Mac OS, and false elsewhere.

       core.protectNTFS
           If set to true, do not allow checkout of paths that would cause
           problems with the NTFS filesystem, e.g. conflict with 8.3 "short"
           names. Defaults to true on Windows, and false elsewhere.

       core.fsmonitor
           If set, the value of this variable is used as a command which will
           identify all files that may have changed since the requested
           date/time. This information is used to speed up git by avoiding
           unnecessary processing of files that have not changed. See the
           "fsmonitor-watchman" section of githooks(5).

       core.fsmonitorHookVersion
           Sets the version of hook that is to be used when calling fsmonitor.
           There are currently versions 1 and 2. When this is not set, version
           2 will be tried first and if it fails then version 1 will be tried.
           Version 1 uses a timestamp as input to determine which files have
           changes since that time but some monitors like watchman have race
           conditions when used with a timestamp. Version 2 uses an opaque
           string so that the monitor can return something that can be used to
           determine what files have changed without race conditions.

       core.trustctime
           If false, the ctime differences between the index and the working
           tree are ignored; useful when the inode change time is regularly
           modified by something outside Git (file system crawlers and some
           backup systems). See git-update-index(1). True by default.

       core.splitIndex
           If true, the split-index feature of the index will be used. See
           git-update-index(1). False by default.

       core.untrackedCache
           Determines what to do about the untracked cache feature of the
           index. It will be kept, if this variable is unset or set to keep.
           It will automatically be added if set to true. And it will
           automatically be removed, if set to false. Before setting it to
           true, you should check that mtime is working properly on your
           system. See git-update-index(1).  keep by default, unless
           feature.manyFiles is enabled which sets this setting to true by
           default.

       core.checkStat
           When missing or is set to default, many fields in the stat
           structure are checked to detect if a file has been modified since
           Git looked at it. When this configuration variable is set to
           minimal, sub-second part of mtime and ctime, the uid and gid of the
           owner of the file, the inode number (and the device number, if Git
           was compiled to use it), are excluded from the check among these
           fields, leaving only the whole-second part of mtime (and ctime, if
           core.trustCtime is set) and the filesize to be checked.

           There are implementations of Git that do not leave usable values in
           some fields (e.g. JGit); by excluding these fields from the
           comparison, the minimal mode may help interoperability when the
           same repository is used by these other systems at the same time.

       core.quotePath
           Commands that output paths (e.g.  ls-files, diff), will quote
           "unusual" characters in the pathname by enclosing the pathname in
           double-quotes and escaping those characters with backslashes in the
           same way C escapes control characters (e.g.  \t for TAB, \n for LF,
           \\ for backslash) or bytes with values larger than 0x80 (e.g. octal
           \302\265 for "micro" in UTF-8). If this variable is set to false,
           bytes higher than 0x80 are not considered "unusual" any more.
           Double-quotes, backslash and control characters are always escaped
           regardless of the setting of this variable. A simple space
           character is not considered "unusual". Many commands can output
           pathnames completely verbatim using the -z option. The default
           value is true.

       core.eol
           Sets the line ending type to use in the working directory for files
           that are marked as text (either by having the text attribute set,
           or by having text=auto and Git auto-detecting the contents as
           text). Alternatives are lf, crlf and native, which uses the
           platform's native line ending. The default value is native. See
           gitattributes(5) for more information on end-of-line conversion.
           Note that this value is ignored if core.autocrlf is set to true or
           input.

       core.safecrlf
           If true, makes Git check if converting CRLF is reversible when
           end-of-line conversion is active. Git will verify if a command
           modifies a file in the work tree either directly or indirectly. For
           example, committing a file followed by checking out the same file
           should yield the original file in the work tree. If this is not the
           case for the current setting of core.autocrlf, Git will reject the
           file. The variable can be set to "warn", in which case Git will
           only warn about an irreversible conversion but continue the
           operation.

           CRLF conversion bears a slight chance of corrupting data. When it
           is enabled, Git will convert CRLF to LF during commit and LF to
           CRLF during checkout. A file that contains a mixture of LF and CRLF
           before the commit cannot be recreated by Git. For text files this
           is the right thing to do: it corrects line endings such that we
           have only LF line endings in the repository. But for binary files
           that are accidentally classified as text the conversion can corrupt
           data.

           If you recognize such corruption early you can easily fix it by
           setting the conversion type explicitly in .gitattributes. Right
           after committing you still have the original file in your work tree
           and this file is not yet corrupted. You can explicitly tell Git
           that this file is binary and Git will handle the file
           appropriately.

           Unfortunately, the desired effect of cleaning up text files with
           mixed line endings and the undesired effect of corrupting binary
           files cannot be distinguished. In both cases CRLFs are removed in
           an irreversible way. For text files this is the right thing to do
           because CRLFs are line endings, while for binary files converting
           CRLFs corrupts data.

           Note, this safety check does not mean that a checkout will generate
           a file identical to the original file for a different setting of
           core.eol and core.autocrlf, but only for the current one. For
           example, a text file with LF would be accepted with core.eol=lf and
           could later be checked out with core.eol=crlf, in which case the
           resulting file would contain CRLF, although the original file
           contained LF. However, in both work trees the line endings would be
           consistent, that is either all LF or all CRLF, but never mixed. A
           file with mixed line endings would be reported by the core.safecrlf
           mechanism.

       core.autocrlf
           Setting this variable to "true" is the same as setting the text
           attribute to "auto" on all files and core.eol to "crlf". Set to
           true if you want to have CRLF line endings in your working
           directory and the repository has LF line endings. This variable can
           be set to input, in which case no output conversion is performed.

       core.checkRoundtripEncoding
           A comma and/or whitespace separated list of encodings that Git
           performs UTF-8 round trip checks on if they are used in an
           working-tree-encoding attribute (see gitattributes(5)). The default
           value is SHIFT-JIS.

       core.symlinks
           If false, symbolic links are checked out as small plain files that
           contain the link text.  git-update-index(1) and git-add(1) will not
           change the recorded type to regular file. Useful on filesystems
           like FAT that do not support symbolic links.

           The default is true, except git-clone(1) or git-init(1) will probe
           and set core.symlinks false if appropriate when the repository is
           created.

       core.gitProxy
           A "proxy command" to execute (as command host port) instead of
           establishing direct connection to the remote server when using the
           Git protocol for fetching. If the variable value is in the "COMMAND
           for DOMAIN" format, the command is applied only on hostnames ending
           with the specified domain string. This variable may be set multiple
           times and is matched in the given order; the first match wins.

           Can be overridden by the GIT_PROXY_COMMAND environment variable
           (which always applies universally, without the special "for"
           handling).

           The special string none can be used as the proxy command to specify
           that no proxy be used for a given domain pattern. This is useful
           for excluding servers inside a firewall from proxy use, while
           defaulting to a common proxy for external domains.

       core.sshCommand
           If this variable is set, git fetch and git push will use the
           specified command instead of ssh when they need to connect to a
           remote system. The command is in the same form as the
           GIT_SSH_COMMAND environment variable and is overridden when the
           environment variable is set.

       core.ignoreStat
           If true, Git will avoid using lstat() calls to detect if files have
           changed by setting the "assume-unchanged" bit for those tracked
           files which it has updated identically in both the index and
           working tree.

           When files are modified outside of Git, the user will need to stage
           the modified files explicitly (e.g. see Examples section in git-
           update-index(1)). Git will not normally detect changes to those
           files.

           This is useful on systems where lstat() calls are very slow, such
           as CIFS/Microsoft Windows.

           False by default.

       core.preferSymlinkRefs
           Instead of the default "symref" format for HEAD and other symbolic
           reference files, use symbolic links. This is sometimes needed to
           work with old scripts that expect HEAD to be a symbolic link.

       core.alternateRefsCommand
           When advertising tips of available history from an alternate, use
           the shell to execute the specified command instead of git-for-each-
           ref(1). The first argument is the absolute path of the alternate.
           Output must contain one hex object id per line (i.e., the same as
           produced by git for-each-ref --format='%(objectname)').

           Note that you cannot generally put git for-each-ref directly into
           the config value, as it does not take a repository path as an
           argument (but you can wrap the command above in a shell script).

       core.alternateRefsPrefixes
           When listing references from an alternate, list only references
           that begin with the given prefix. Prefixes match as if they were
           given as arguments to git-for-each-ref(1). To list multiple
           prefixes, separate them with whitespace. If
           core.alternateRefsCommand is set, setting
           core.alternateRefsPrefixes has no effect.

       core.bare
           If true this repository is assumed to be bare and has no working
           directory associated with it. If this is the case a number of
           commands that require a working directory will be disabled, such as
           git-add(1) or git-merge(1).

           This setting is automatically guessed by git-clone(1) or git-
           init(1) when the repository was created. By default a repository
           that ends in "/.git" is assumed to be not bare (bare = false),
           while all other repositories are assumed to be bare (bare = true).

       core.worktree
           Set the path to the root of the working tree. If GIT_COMMON_DIR
           environment variable is set, core.worktree is ignored and not used
           for determining the root of working tree. This can be overridden by
           the GIT_WORK_TREE environment variable and the --work-tree
           command-line option. The value can be an absolute path or relative
           to the path to the .git directory, which is either specified by
           --git-dir or GIT_DIR, or automatically discovered. If --git-dir or
           GIT_DIR is specified but none of --work-tree, GIT_WORK_TREE and
           core.worktree is specified, the current working directory is
           regarded as the top level of your working tree.

           Note that this variable is honored even when set in a configuration
           file in a ".git" subdirectory of a directory and its value differs
           from the latter directory (e.g. "/path/to/.git/config" has
           core.worktree set to "/different/path"), which is most likely a
           misconfiguration. Running Git commands in the "/path/to" directory
           will still use "/different/path" as the root of the work tree and
           can cause confusion unless you know what you are doing (e.g. you
           are creating a read-only snapshot of the same index to a location
           different from the repository's usual working tree).

       core.logAllRefUpdates
           Enable the reflog. Updates to a ref <ref> is logged to the file
           "$GIT_DIR/logs/<ref>", by appending the new and old SHA-1, the
           date/time and the reason of the update, but only when the file
           exists. If this configuration variable is set to true, missing
           "$GIT_DIR/logs/<ref>" file is automatically created for branch
           heads (i.e. under refs/heads/), remote refs (i.e. under
           refs/remotes/), note refs (i.e. under refs/notes/), and the
           symbolic ref HEAD. If it is set to always, then a missing reflog is
           automatically created for any ref under refs/.

           This information can be used to determine what commit was the tip
           of a branch "2 days ago".

           This value is true by default in a repository that has a working
           directory associated with it, and false by default in a bare
           repository.

       core.repositoryFormatVersion
           Internal variable identifying the repository format and layout
           version.

       core.sharedRepository
           When group (or true), the repository is made shareable between
           several users in a group (making sure all the files and objects are
           group-writable). When all (or world or everybody), the repository
           will be readable by all users, additionally to being
           group-shareable. When umask (or false), Git will use permissions
           reported by umask(2). When 0xxx, where 0xxx is an octal number,
           files in the repository will have this mode value.  0xxx will
           override user's umask value (whereas the other options will only
           override requested parts of the user's umask value). Examples: 0660
           will make the repo read/write-able for the owner and group, but
           inaccessible to others (equivalent to group unless umask is e.g.
           0022).  0640 is a repository that is group-readable but not
           group-writable. See git-init(1). False by default.

       core.warnAmbiguousRefs
           If true, Git will warn you if the ref name you passed it is
           ambiguous and might match multiple refs in the repository. True by
           default.

       core.compression
           An integer -1..9, indicating a default compression level. -1 is the
           zlib default. 0 means no compression, and 1..9 are various
           speed/size tradeoffs, 9 being slowest. If set, this provides a
           default to other compression variables, such as
           core.looseCompression and pack.compression.

       core.looseCompression
           An integer -1..9, indicating the compression level for objects that
           are not in a pack file. -1 is the zlib default. 0 means no
           compression, and 1..9 are various speed/size tradeoffs, 9 being
           slowest. If not set, defaults to core.compression. If that is not
           set, defaults to 1 (best speed).

       core.packedGitWindowSize
           Number of bytes of a pack file to map into memory in a single
           mapping operation. Larger window sizes may allow your system to
           process a smaller number of large pack files more quickly. Smaller
           window sizes will negatively affect performance due to increased
           calls to the operating system's memory manager, but may improve
           performance when accessing a large number of large pack files.

           Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
           MiB on 32 bit platforms and 1 GiB on 64 bit platforms. This should
           be reasonable for all users/operating systems. You probably do not
           need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.packedGitLimit
           Maximum number of bytes to map simultaneously into memory from pack
           files. If Git needs to access more than this many bytes at once to
           complete an operation it will unmap existing regions to reclaim
           virtual address space within the process.

           Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
           unlimited) on 64 bit platforms. This should be reasonable for all
           users/operating systems, except on the largest projects. You
           probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.deltaBaseCacheLimit
           Maximum number of bytes to reserve for caching base objects that
           may be referenced by multiple deltified objects. By storing the
           entire decompressed base objects in a cache Git is able to avoid
           unpacking and decompressing frequently used base objects multiple
           times.

           Default is 96 MiB on all platforms. This should be reasonable for
           all users/operating systems, except on the largest projects. You
           probably do not need to adjust this value.

           Common unit suffixes of k, m, or g are supported.

       core.bigFileThreshold
           Files larger than this size are stored deflated, without attempting
           delta compression. Storing large files without delta compression
           avoids excessive memory usage, at the slight expense of increased
           disk usage. Additionally files larger than this size are always
           treated as binary.

           Default is 512 MiB on all platforms. This should be reasonable for
           most projects as source code and other text files can still be
           delta compressed, but larger binary media files won't be.

           Common unit suffixes of k, m, or g are supported.

       core.excludesFile
           Specifies the pathname to the file that contains patterns to
           describe paths that are not meant to be tracked, in addition to
           .gitignore (per-directory) and .git/info/exclude. Defaults to
           $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set
           or empty, $HOME/.config/git/ignore is used instead. See
           gitignore(5).

       core.askPass
           Some commands (e.g. svn and http interfaces) that interactively ask
           for a password can be told to use an external program given via the
           value of this variable. Can be overridden by the GIT_ASKPASS
           environment variable. If not set, fall back to the value of the
           SSH_ASKPASS environment variable or, failing that, a simple
           password prompt. The external program shall be given a suitable
           prompt as command-line argument and write the password on its
           STDOUT.

       core.attributesFile
           In addition to .gitattributes (per-directory) and
           .git/info/attributes, Git looks into this file for attributes (see
           gitattributes(5)). Path expansions are made the same way as for
           core.excludesFile. Its default value is
           $XDG_CONFIG_HOME/git/attributes. If $XDG_CONFIG_HOME is either not
           set or empty, $HOME/.config/git/attributes is used instead.

       core.hooksPath
           By default Git will look for your hooks in the $GIT_DIR/hooks
           directory. Set this to different path, e.g.  /etc/git/hooks, and
           Git will try to find your hooks in that directory, e.g.
           /etc/git/hooks/pre-receive instead of in
           $GIT_DIR/hooks/pre-receive.

           The path can be either absolute or relative. A relative path is
           taken as relative to the directory where the hooks are run (see the
           "DESCRIPTION" section of githooks(5)).

           This configuration variable is useful in cases where you'd like to
           centrally configure your Git hooks instead of configuring them on a
           per-repository basis, or as a more flexible and centralized
           alternative to having an init.templateDir where you've changed
           default hooks.

       core.editor
           Commands such as commit and tag that let you edit messages by
           launching an editor use the value of this variable when it is set,
           and the environment variable GIT_EDITOR is not set. See git-var(1).

       core.commentChar
           Commands such as commit and tag that let you edit messages consider
           a line that begins with this character commented, and removes them
           after the editor returns (default #).

           If set to "auto", git-commit would select a character that is not
           the beginning character of any line in existing commit messages.

       core.filesRefLockTimeout
           The length of time, in milliseconds, to retry when trying to lock
           an individual reference. Value 0 means not to retry at all; -1
           means to try indefinitely. Default is 100 (i.e., retry for 100ms).

       core.packedRefsTimeout
           The length of time, in milliseconds, to retry when trying to lock
           the packed-refs file. Value 0 means not to retry at all; -1 means
           to try indefinitely. Default is 1000 (i.e., retry for 1 second).

       core.pager
           Text viewer for use by Git commands (e.g., less). The value is
           meant to be interpreted by the shell. The order of preference is
           the $GIT_PAGER environment variable, then core.pager configuration,
           then $PAGER, and then the default chosen at compile time (usually
           less).

           When the LESS environment variable is unset, Git sets it to FRX (if
           LESS environment variable is set, Git does not change it at all).
           If you want to selectively override Git's default setting for LESS,
           you can set core.pager to e.g.  less -S. This will be passed to the
           shell by Git, which will translate the final command to LESS=FRX
           less -S. The environment does not set the S option but the command
           line does, instructing less to truncate long lines. Similarly,
           setting core.pager to less -+F will deactivate the F option
           specified by the environment from the command-line, deactivating
           the "quit if one screen" behavior of less. One can specifically
           activate some flags for particular commands: for example, setting
           pager.blame to less -S enables line truncation only for git blame.

           Likewise, when the LV environment variable is unset, Git sets it to
           -c. You can override this setting by exporting LV with another
           value or setting core.pager to lv +c.

       core.whitespace
           A comma separated list of common whitespace problems to notice.
           git diff will use color.diff.whitespace to highlight them, and git
           apply --whitespace=error will consider them as errors. You can
           prefix - to disable any of them (e.g.  -trailing-space):

           o   blank-at-eol treats trailing whitespaces at the end of the line
               as an error (enabled by default).

           o   space-before-tab treats a space character that appears
               immediately before a tab character in the initial indent part
               of the line as an error (enabled by default).

           o   indent-with-non-tab treats a line that is indented with space
               characters instead of the equivalent tabs as an error (not
               enabled by default).

           o   tab-in-indent treats a tab character in the initial indent part
               of the line as an error (not enabled by default).

           o   blank-at-eof treats blank lines added at the end of file as an
               error (enabled by default).

           o   trailing-space is a short-hand to cover both blank-at-eol and
               blank-at-eof.

           o   cr-at-eol treats a carriage-return at the end of line as part
               of the line terminator, i.e. with it, trailing-space does not
               trigger if the character before such a carriage-return is not a
               whitespace (not enabled by default).

           o   tabwidth=<n> tells how many character positions a tab occupies;
               this is relevant for indent-with-non-tab and when Git fixes
               tab-in-indent errors. The default tab width is 8. Allowed
               values are 1 to 63.

       core.fsyncObjectFiles
           This boolean will enable fsync() when writing object files.

           This is a total waste of time and effort on a filesystem that
           orders data writes properly, but can be useful for filesystems that
           do not use journalling (traditional UNIX filesystems) or that only
           journal metadata and not file contents (OS X's HFS+, or Linux ext3
           with "data=writeback").

       core.preloadIndex
           Enable parallel index preload for operations like git diff

           This can speed up operations like git diff and git status
           especially on filesystems like NFS that have weak caching semantics
           and thus relatively high IO latencies. When enabled, Git will do
           the index comparison to the filesystem data in parallel, allowing
           overlapping IO's. Defaults to true.

       core.unsetenvvars
           Windows-only: comma-separated list of environment variables' names
           that need to be unset before spawning any other process. Defaults
           to PERL5LIB to account for the fact that Git for Windows insists on
           using its own Perl interpreter.

       core.restrictinheritedhandles
           Windows-only: override whether spawned processes inherit only
           standard file handles (stdin, stdout and stderr) or all handles.
           Can be auto, true or false. Defaults to auto, which means true on
           Windows 7 and later, and false on older Windows versions.

       core.createObject
           You can set this to link, in which case a hardlink followed by a
           delete of the source are used to make sure that object creation
           will not overwrite existing objects.

           On some file system/operating system combinations, this is
           unreliable. Set this config setting to rename there; However, This
           will remove the check that makes sure that existing object files
           will not get overwritten.

       core.notesRef
           When showing commit messages, also show notes which are stored in
           the given ref. The ref must be fully qualified. If the given ref
           does not exist, it is not an error but means that no notes should
           be printed.

           This setting defaults to "refs/notes/commits", and it can be
           overridden by the GIT_NOTES_REF environment variable. See git-
           notes(1).

       core.commitGraph
           If true, then git will read the commit-graph file (if it exists) to
           parse the graph structure of commits. Defaults to true. See git-
           commit-graph(1) for more information.

       core.useReplaceRefs
           If set to false, behave as if the --no-replace-objects option was
           given on the command line. See git(1) and git-replace(1) for more
           information.

       core.multiPackIndex
           Use the multi-pack-index file to track multiple packfiles using a
           single index. See the multi-pack-index design document[1].

       core.sparseCheckout
           Enable "sparse checkout" feature. See git-sparse-checkout(1) for
           more information.

       core.sparseCheckoutCone
           Enables the "cone mode" of the sparse checkout feature. When the
           sparse-checkout file contains a limited set of patterns, then this
           mode provides significant performance advantages. See git-sparse-
           checkout(1) for more information.

       core.abbrev
           Set the length object names are abbreviated to. If unspecified or
           set to "auto", an appropriate value is computed based on the
           approximate number of packed objects in your repository, which
           hopefully is enough for abbreviated object names to stay unique for
           some time. The minimum length is 4.

       add.ignoreErrors, add.ignore-errors (deprecated)
           Tells git add to continue adding files when some files cannot be
           added due to indexing errors. Equivalent to the --ignore-errors
           option of git-add(1).  add.ignore-errors is deprecated, as it does
           not follow the usual naming convention for configuration variables.

       add.interactive.useBuiltin
           [EXPERIMENTAL] Set to true to use the experimental built-in
           implementation of the interactive version of git-add(1) instead of
           the Perl script version. Is false by default.

       alias.*
           Command aliases for the git(1) command wrapper - e.g. after
           defining alias.last = cat-file commit HEAD, the invocation git last
           is equivalent to git cat-file commit HEAD. To avoid confusion and
           troubles with script usage, aliases that hide existing Git commands
           are ignored. Arguments are split by spaces, the usual shell quoting
           and escaping is supported. A quote pair or a backslash can be used
           to quote them.

           Note that the first word of an alias does not necessarily have to
           be a command. It can be a command-line option that will be passed
           into the invocation of git. In particular, this is useful when used
           with -c to pass in one-time configurations or -p to force
           pagination. For example, loud-rebase = -c commit.verbose=true
           rebase can be defined such that running git loud-rebase would be
           equivalent to git -c commit.verbose=true rebase. Also, ps = -p
           status would be a helpful alias since git ps would paginate the
           output of git status where the original command does not.

           If the alias expansion is prefixed with an exclamation point, it
           will be treated as a shell command. For example, defining alias.new
           = !gitk --all --not ORIG_HEAD, the invocation git new is equivalent
           to running the shell command gitk --all --not ORIG_HEAD. Note that
           shell commands will be executed from the top-level directory of a
           repository, which may not necessarily be the current directory.
           GIT_PREFIX is set as returned by running git rev-parse
           --show-prefix from the original current directory. See git-rev-
           parse(1).

       am.keepcr
           If true, git-am will call git-mailsplit for patches in mbox format
           with parameter --keep-cr. In this case git-mailsplit will not
           remove \r from lines ending with \r\n. Can be overridden by giving
           --no-keep-cr from the command line. See git-am(1), git-
           mailsplit(1).

       am.threeWay
           By default, git am will fail if the patch does not apply cleanly.
           When set to true, this setting tells git am to fall back on 3-way
           merge if the patch records the identity of blobs it is supposed to
           apply to and we have those blobs available locally (equivalent to
           giving the --3way option from the command line). Defaults to false.
           See git-am(1).

       apply.ignoreWhitespace
           When set to change, tells git apply to ignore changes in
           whitespace, in the same way as the --ignore-space-change option.
           When set to one of: no, none, never, false tells git apply to
           respect all whitespace differences. See git-apply(1).

       apply.whitespace
           Tells git apply how to handle whitespaces, in the same way as the
           --whitespace option. See git-apply(1).

       blame.blankBoundary
           Show blank commit object name for boundary commits in git-blame(1).
           This option defaults to false.

       blame.coloring
           This determines the coloring scheme to be applied to blame output.
           It can be repeatedLines, highlightRecent, or none which is the
           default.

       blame.date
           Specifies the format used to output dates in git-blame(1). If unset
           the iso format is used. For supported values, see the discussion of
           the --date option at git-log(1).

       blame.showEmail
           Show the author email instead of author name in git-blame(1). This
           option defaults to false.

       blame.showRoot
           Do not treat root commits as boundaries in git-blame(1). This
           option defaults to false.

       blame.ignoreRevsFile
           Ignore revisions listed in the file, one unabbreviated object name
           per line, in git-blame(1). Whitespace and comments beginning with #
           are ignored. This option may be repeated multiple times. Empty file
           names will reset the list of ignored revisions. This option will be
           handled before the command line option --ignore-revs-file.

       blame.markUnblamables
           Mark lines that were changed by an ignored revision that we could
           not attribute to another commit with a * in the output of git-
           blame(1).

       blame.markIgnoredLines
           Mark lines that were changed by an ignored revision that we
           attributed to another commit with a ?  in the output of git-
           blame(1).

       branch.autoSetupMerge
           Tells git branch, git switch and git checkout to set up new
           branches so that git-pull(1) will appropriately merge from the
           starting point branch. Note that even if this option is not set,
           this behavior can be chosen per-branch using the --track and
           --no-track options. The valid settings are: false -- no automatic
           setup is done; true -- automatic setup is done when the starting
           point is a remote-tracking branch; always --  automatic setup is
           done when the starting point is either a local branch or
           remote-tracking branch. This option defaults to true.

       branch.autoSetupRebase
           When a new branch is created with git branch, git switch or git
           checkout that tracks another branch, this variable tells Git to set
           up pull to rebase instead of merge (see "branch.<name>.rebase").
           When never, rebase is never automatically set to true. When local,
           rebase is set to true for tracked branches of other local branches.
           When remote, rebase is set to true for tracked branches of
           remote-tracking branches. When always, rebase will be set to true
           for all tracking branches. See "branch.autoSetupMerge" for details
           on how to set up a branch to track another branch. This option
           defaults to never.

       branch.sort
           This variable controls the sort ordering of branches when displayed
           by git-branch(1). Without the "--sort=<value>" option provided, the
           value of this variable will be used as the default. See git-for-
           each-ref(1) field names for valid values.

       branch.<name>.remote
           When on branch <name>, it tells git fetch and git push which remote
           to fetch from/push to. The remote to push to may be overridden with
           remote.pushDefault (for all branches). The remote to push to, for
           the current branch, may be further overridden by
           branch.<name>.pushRemote. If no remote is configured, or if you are
           not on any branch, it defaults to origin for fetching and
           remote.pushDefault for pushing. Additionally, .  (a period) is the
           current local repository (a dot-repository), see
           branch.<name>.merge's final note below.

       branch.<name>.pushRemote
           When on branch <name>, it overrides branch.<name>.remote for
           pushing. It also overrides remote.pushDefault for pushing from
           branch <name>. When you pull from one place (e.g. your upstream)
           and push to another place (e.g. your own publishing repository),
           you would want to set remote.pushDefault to specify the remote to
           push to for all branches, and use this option to override it for a
           specific branch.

       branch.<name>.merge
           Defines, together with branch.<name>.remote, the upstream branch
           for the given branch. It tells git fetch/git pull/git rebase which
           branch to merge and can also affect git push (see push.default).
           When in branch <name>, it tells git fetch the default refspec to be
           marked for merging in FETCH_HEAD. The value is handled like the
           remote part of a refspec, and must match a ref which is fetched
           from the remote given by "branch.<name>.remote". The merge
           information is used by git pull (which at first calls git fetch) to
           lookup the default branch for merging. Without this option, git
           pull defaults to merge the first refspec fetched. Specify multiple
           values to get an octopus merge. If you wish to setup git pull so
           that it merges into <name> from another branch in the local
           repository, you can point branch.<name>.merge to the desired
           branch, and use the relative path setting .  (a period) for
           branch.<name>.remote.

       branch.<name>.mergeOptions
           Sets default options for merging into branch <name>. The syntax and
           supported options are the same as those of git-merge(1), but option
           values containing whitespace characters are currently not
           supported.

       branch.<name>.rebase
           When true, rebase the branch <name> on top of the fetched branch,
           instead of merging the default branch from the default remote when
           "git pull" is run. See "pull.rebase" for doing this in a non
           branch-specific manner.

           When merges (or just m), pass the --rebase-merges option to git
           rebase so that the local merge commits are included in the rebase
           (see git-rebase(1) for details).

           When preserve (or just p, deprecated in favor of merges), also pass
           --preserve-merges along to git rebase so that locally committed
           merge commits will not be flattened by running git pull.

           When the value is interactive (or just i), the rebase is run in
           interactive mode.

           NOTE: this is a possibly dangerous operation; do not use it unless
           you understand the implications (see git-rebase(1) for details).

       branch.<name>.description
           Branch description, can be edited with git branch
           --edit-description. Branch description is automatically added in
           the format-patch cover letter or request-pull summary.

       browser.<tool>.cmd
           Specify the command to invoke the specified browser. The specified
           command is evaluated in shell with the URLs passed as arguments.
           (See git-web--browse(1).)

       browser.<tool>.path
           Override the path for the given tool that may be used to browse
           HTML help (see -w option in git-help(1)) or a working repository in
           gitweb (see git-instaweb(1)).

       checkout.defaultRemote
           When you run git checkout <something> or git switch <something> and
           only have one remote, it may implicitly fall back on checking out
           and tracking e.g.  origin/<something>. This stops working as soon
           as you have more than one remote with a <something> reference. This
           setting allows for setting the name of a preferred remote that
           should always win when it comes to disambiguation. The typical
           use-case is to set this to origin.

           Currently this is used by git-switch(1) and git-checkout(1) when
           git checkout <something> or git switch <something> will checkout
           the <something> branch on another remote, and by git-worktree(1)
           when git worktree add refers to a remote branch. This setting might
           be used for other checkout-like commands or functionality in the
           future.

       clean.requireForce
           A boolean to make git-clean do nothing unless given -f, -i or -n.
           Defaults to true.

       color.advice
           A boolean to enable/disable color in hints (e.g. when a push
           failed, see advice.*  for a list). May be set to always, false (or
           never) or auto (or true), in which case colors are used only when
           the error output goes to a terminal. If unset, then the value of
           color.ui is used (auto by default).

       color.advice.hint
           Use customized color for hints.

       color.blame.highlightRecent
           This can be used to color the metadata of a blame line depending on
           age of the line.

           This setting should be set to a comma-separated list of color and
           date settings, starting and ending with a color, the dates should
           be set from oldest to newest. The metadata will be colored given
           the colors if the line was introduced before the given timestamp,
           overwriting older timestamped colors.

           Instead of an absolute timestamp relative timestamps work as well,
           e.g. 2.weeks.ago is valid to address anything older than 2 weeks.

           It defaults to blue,12 month ago,white,1 month ago,red, which
           colors everything older than one year blue, recent changes between
           one month and one year old are kept white, and lines introduced
           within the last month are colored red.

       color.blame.repeatedLines
           Use the customized color for the part of git-blame output that is
           repeated meta information per line (such as commit id, author name,
           date and timezone). Defaults to cyan.

       color.branch
           A boolean to enable/disable color in the output of git-branch(1).
           May be set to always, false (or never) or auto (or true), in which
           case colors are used only when the output is to a terminal. If
           unset, then the value of color.ui is used (auto by default).

       color.branch.<slot>
           Use customized color for branch coloration.  <slot> is one of
           current (the current branch), local (a local branch), remote (a
           remote-tracking branch in refs/remotes/), upstream (upstream
           tracking branch), plain (other refs).

       color.diff
           Whether to use ANSI escape sequences to add color to patches. If
           this is set to always, git-diff(1), git-log(1), and git-show(1)
           will use color for all patches. If it is set to true or auto, those
           commands will only use color when output is to the terminal. If
           unset, then the value of color.ui is used (auto by default).

           This does not affect git-format-patch(1) or the git-diff-* plumbing
           commands. Can be overridden on the command line with the
           --color[=<when>] option.

       color.diff.<slot>
           Use customized color for diff colorization.  <slot> specifies which
           part of the patch to use the specified color, and is one of context
           (context text - plain is a historical synonym), meta
           (metainformation), frag (hunk header), func (function in hunk
           header), old (removed lines), new (added lines), commit (commit
           headers), whitespace (highlighting whitespace errors), oldMoved
           (deleted lines), newMoved (added lines), oldMovedDimmed,
           oldMovedAlternative, oldMovedAlternativeDimmed, newMovedDimmed,
           newMovedAlternative newMovedAlternativeDimmed (See the <mode>
           setting of --color-moved in git-diff(1) for details),
           contextDimmed, oldDimmed, newDimmed, contextBold, oldBold, and
           newBold (see git-range-diff(1) for details).

       color.decorate.<slot>
           Use customized color for git log --decorate output.  <slot> is one
           of branch, remoteBranch, tag, stash or HEAD for local branches,
           remote-tracking branches, tags, stash and HEAD, respectively and
           grafted for grafted commits.

       color.grep
           When set to always, always highlight matches. When false (or
           never), never. When set to true or auto, use color only when the
           output is written to the terminal. If unset, then the value of
           color.ui is used (auto by default).

       color.grep.<slot>
           Use customized color for grep colorization.  <slot> specifies which
           part of the line to use the specified color, and is one of

           context
               non-matching text in context lines (when using -A, -B, or -C)

           filename
               filename prefix (when not using -h)

           function
               function name lines (when using -p)

           lineNumber
               line number prefix (when using -n)

           column
               column number prefix (when using --column)

           match
               matching text (same as setting matchContext and matchSelected)

           matchContext
               matching text in context lines

           matchSelected
               matching text in selected lines

           selected
               non-matching text in selected lines

           separator
               separators between fields on a line (:, -, and =) and between
               hunks (--)

       color.interactive
           When set to always, always use colors for interactive prompts and
           displays (such as those used by "git-add --interactive" and
           "git-clean --interactive"). When false (or never), never. When set
           to true or auto, use colors only when the output is to the
           terminal. If unset, then the value of color.ui is used (auto by
           default).

       color.interactive.<slot>
           Use customized color for git add --interactive and git clean
           --interactive output.  <slot> may be prompt, header, help or error,
           for four distinct types of normal output from interactive commands.

       color.pager
           A boolean to enable/disable colored output when the pager is in use
           (default is true).

       color.push
           A boolean to enable/disable color in push errors. May be set to
           always, false (or never) or auto (or true), in which case colors
           are used only when the error output goes to a terminal. If unset,
           then the value of color.ui is used (auto by default).

       color.push.error
           Use customized color for push errors.

       color.remote
           If set, keywords at the start of the line are highlighted. The
           keywords are "error", "warning", "hint" and "success", and are
           matched case-insensitively. May be set to always, false (or never)
           or auto (or true). If unset, then the value of color.ui is used
           (auto by default).

       color.remote.<slot>
           Use customized color for each remote keyword.  <slot> may be hint,
           warning, success or error which match the corresponding keyword.

       color.showBranch
           A boolean to enable/disable color in the output of git-show-
           branch(1). May be set to always, false (or never) or auto (or
           true), in which case colors are used only when the output is to a
           terminal. If unset, then the value of color.ui is used (auto by
           default).

       color.status
           A boolean to enable/disable color in the output of git-status(1).
           May be set to always, false (or never) or auto (or true), in which
           case colors are used only when the output is to a terminal. If
           unset, then the value of color.ui is used (auto by default).

       color.status.<slot>
           Use customized color for status colorization.  <slot> is one of
           header (the header text of the status message), added or updated
           (files which are added but not committed), changed (files which are
           changed but not added in the index), untracked (files which are not
           tracked by Git), branch (the current branch), nobranch (the color
           the no branch warning is shown in, defaulting to red), localBranch
           or remoteBranch (the local and remote branch names, respectively,
           when branch and tracking information is displayed in the status
           short-format), or unmerged (files which have unmerged changes).

       color.transport
           A boolean to enable/disable color when pushes are rejected. May be
           set to always, false (or never) or auto (or true), in which case
           colors are used only when the error output goes to a terminal. If
           unset, then the value of color.ui is used (auto by default).

       color.transport.rejected
           Use customized color when a push was rejected.

       color.ui
           This variable determines the default value for variables such as
           color.diff and color.grep that control the use of color per command
           family. Its scope will expand as more commands learn configuration
           to set a default for the --color option. Set it to false or never
           if you prefer Git commands not to use color unless enabled
           explicitly with some other configuration or the --color option. Set
           it to always if you want all output not intended for machine
           consumption to use color, to true or auto (this is the default
           since Git 1.8.4) if you want such output to use color when written
           to the terminal.

       column.ui
           Specify whether supported commands should output in columns. This
           variable consists of a list of tokens separated by spaces or
           commas:

           These options control when the feature should be enabled (defaults
           to never):

           always
               always show in columns

           never
               never show in columns

           auto
               show in columns if the output is to the terminal

           These options control layout (defaults to column). Setting any of
           these implies always if none of always, never, or auto are
           specified.

           column
               fill columns before rows

           row
               fill rows before columns

           plain
               show in one column

           Finally, these options can be combined with a layout option
           (defaults to nodense):

           dense
               make unequal size columns to utilize more space

           nodense
               make equal size columns

       column.branch
           Specify whether to output branch listing in git branch in columns.
           See column.ui for details.

       column.clean
           Specify the layout when list items in git clean -i, which always
           shows files and directories in columns. See column.ui for details.

       column.status
           Specify whether to output untracked files in git status in columns.
           See column.ui for details.

       column.tag
           Specify whether to output tag listing in git tag in columns. See
           column.ui for details.

       commit.cleanup
           This setting overrides the default of the --cleanup option in git
           commit. See git-commit(1) for details. Changing the default can be
           useful when you always want to keep lines that begin with comment
           character # in your log message, in which case you would do git
           config commit.cleanup whitespace (note that you will have to remove
           the help lines that begin with # in the commit log template
           yourself, if you do this).

       commit.gpgSign
           A boolean to specify whether all commits should be GPG signed. Use
           of this option when doing operations such as rebase can result in a
           large number of commits being signed. It may be convenient to use
           an agent to avoid typing your GPG passphrase several times.

       commit.status
           A boolean to enable/disable inclusion of status information in the
           commit message template when using an editor to prepare the commit
           message. Defaults to true.

       commit.template
           Specify the pathname of a file to use as the template for new
           commit messages.

       commit.verbose
           A boolean or int to specify the level of verbose with git commit.
           See git-commit(1).

       credential.helper
           Specify an external helper to be called when a username or password
           credential is needed; the helper may consult external storage to
           avoid prompting the user for the credentials. This is normally the
           name of a credential helper with possible arguments, but may also
           be an absolute path with arguments or, if preceded by !, shell
           commands.

           Note that multiple helpers may be defined. See gitcredentials(7)
           for details and examples.

       credential.useHttpPath
           When acquiring credentials, consider the "path" component of an
           http or https URL to be important. Defaults to false. See
           gitcredentials(7) for more information.

       credential.username
           If no username is set for a network authentication, use this
           username by default. See credential.<context>.* below, and
           gitcredentials(7).

       credential.<url>.*
           Any of the credential.* options above can be applied selectively to
           some credentials. For example
           "credential.https://example.com.username" would set the default
           username only for https connections to example.com. See
           gitcredentials(7) for details on how URLs are matched.

       credentialCache.ignoreSIGHUP
           Tell git-credential-cache--daemon to ignore SIGHUP, instead of
           quitting.

       completion.commands
           This is only used by git-completion.bash to add or remove commands
           from the list of completed commands. Normally only porcelain
           commands and a few select others are completed. You can add more
           commands, separated by space, in this variable. Prefixing the
           command with - will remove it from the existing list.

       diff.autoRefreshIndex
           When using git diff to compare with work tree files, do not
           consider stat-only change as changed. Instead, silently run git
           update-index --refresh to update the cached stat information for
           paths whose contents in the work tree match the contents in the
           index. This option defaults to true. Note that this affects only
           git diff Porcelain, and not lower level diff commands such as git
           diff-files.

       diff.dirstat
           A comma separated list of --dirstat parameters specifying the
           default behavior of the --dirstat option to git-diff(1) and
           friends. The defaults can be overridden on the command line (using
           --dirstat=<param1,param2,...>). The fallback defaults (when not
           changed by diff.dirstat) are changes,noncumulative,3. The following
           parameters are available:

           changes
               Compute the dirstat numbers by counting the lines that have
               been removed from the source, or added to the destination. This
               ignores the amount of pure code movements within a file. In
               other words, rearranging lines in a file is not counted as much
               as other changes. This is the default behavior when no
               parameter is given.

           lines
               Compute the dirstat numbers by doing the regular line-based
               diff analysis, and summing the removed/added line counts. (For
               binary files, count 64-byte chunks instead, since binary files
               have no natural concept of lines). This is a more expensive
               --dirstat behavior than the changes behavior, but it does count
               rearranged lines within a file as much as other changes. The
               resulting output is consistent with what you get from the other
               --*stat options.

           files
               Compute the dirstat numbers by counting the number of files
               changed. Each changed file counts equally in the dirstat
               analysis. This is the computationally cheapest --dirstat
               behavior, since it does not have to look at the file contents
               at all.

           cumulative
               Count changes in a child directory for the parent directory as
               well. Note that when using cumulative, the sum of the
               percentages reported may exceed 100%. The default
               (non-cumulative) behavior can be specified with the
               noncumulative parameter.

           <limit>
               An integer parameter specifies a cut-off percent (3% by
               default). Directories contributing less than this percentage of
               the changes are not shown in the output.

           Example: The following will count changed files, while ignoring
           directories with less than 10% of the total amount of changed
           files, and accumulating child directory counts in the parent
           directories: files,10,cumulative.

       diff.statGraphWidth
           Limit the width of the graph part in --stat output. If set, applies
           to all commands generating --stat output except format-patch.

       diff.context
           Generate diffs with <n> lines of context instead of the default of
           3. This value is overridden by the -U option.

       diff.interHunkContext
           Show the context between diff hunks, up to the specified number of
           lines, thereby fusing the hunks that are close to each other. This
           value serves as the default for the --inter-hunk-context command
           line option.

       diff.external
           If this config variable is set, diff generation is not performed
           using the internal diff machinery, but using the given command. Can
           be overridden with the 'GIT_EXTERNAL_DIFF' environment variable.
           The command is called with parameters as described under "git
           Diffs" in git(1). Note: if you want to use an external diff program
           only on a subset of your files, you might want to use
           gitattributes(5) instead.

       diff.ignoreSubmodules
           Sets the default value of --ignore-submodules. Note that this
           affects only git diff Porcelain, and not lower level diff commands
           such as git diff-files.  git checkout and git switch also honor
           this setting when reporting uncommitted changes. Setting it to all
           disables the submodule summary normally shown by git commit and git
           status when status.submoduleSummary is set unless it is overridden
           by using the --ignore-submodules command-line option. The git
           submodule commands are not affected by this setting.

       diff.mnemonicPrefix
           If set, git diff uses a prefix pair that is different from the
           standard "a/" and "b/" depending on what is being compared. When
           this configuration is in effect, reverse diff output also swaps the
           order of the prefixes:

           git diff
               compares the (i)ndex and the (w)ork tree;

           git diff HEAD
               compares a (c)ommit and the (w)ork tree;

           git diff --cached
               compares a (c)ommit and the (i)ndex;

           git diff HEAD:file1 file2
               compares an (o)bject and a (w)ork tree entity;

           git diff --no-index a b
               compares two non-git things (1) and (2).

       diff.noprefix
           If set, git diff does not show any source or destination prefix.

       diff.orderFile
           File indicating how to order files within a diff. See the -O option
           to git-diff(1) for details. If diff.orderFile is a relative
           pathname, it is treated as relative to the top of the working tree.

       diff.renameLimit
           The number of files to consider when performing the copy/rename
           detection; equivalent to the git diff option -l. This setting has
           no effect if rename detection is turned off.

       diff.renames
           Whether and how Git detects renames. If set to "false", rename
           detection is disabled. If set to "true", basic rename detection is
           enabled. If set to "copies" or "copy", Git will detect copies, as
           well. Defaults to true. Note that this affects only git diff
           Porcelain like git-diff(1) and git-log(1), and not lower level
           commands such as git-diff-files(1).

       diff.suppressBlankEmpty
           A boolean to inhibit the standard behavior of printing a space
           before each empty output line. Defaults to false.

       diff.submodule
           Specify the format in which differences in submodules are shown.
           The "short" format just shows the names of the commits at the
           beginning and end of the range. The "log" format lists the commits
           in the range like git-submodule(1) summary does. The "diff" format
           shows an inline diff of the changed contents of the submodule.
           Defaults to "short".

       diff.wordRegex
           A POSIX Extended Regular Expression used to determine what is a
           "word" when performing word-by-word difference calculations.
           Character sequences that match the regular expression are "words",
           all other characters are ignorable whitespace.

       diff.<driver>.command
           The custom diff driver command. See gitattributes(5) for details.

       diff.<driver>.xfuncname
           The regular expression that the diff driver should use to recognize
           the hunk header. A built-in pattern may also be used. See
           gitattributes(5) for details.

       diff.<driver>.binary
           Set this option to true to make the diff driver treat files as
           binary. See gitattributes(5) for details.

       diff.<driver>.textconv
           The command that the diff driver should call to generate the
           text-converted version of a file. The result of the conversion is
           used to generate a human-readable diff. See gitattributes(5) for
           details.

       diff.<driver>.wordRegex
           The regular expression that the diff driver should use to split
           words in a line. See gitattributes(5) for details.

       diff.<driver>.cachetextconv
           Set this option to true to make the diff driver cache the text
           conversion outputs. See gitattributes(5) for details.

       diff.tool
           Controls which diff tool is used by git-difftool(1). This variable
           overrides the value configured in merge.tool. The list below shows
           the valid built-in values. Any other value is treated as a custom
           diff tool and requires that a corresponding difftool.<tool>.cmd
           variable is defined.

       diff.guitool
           Controls which diff tool is used by git-difftool(1) when the
           -g/--gui flag is specified. This variable overrides the value
           configured in merge.guitool. The list below shows the valid
           built-in values. Any other value is treated as a custom diff tool
           and requires that a corresponding difftool.<guitool>.cmd variable
           is defined.

       diff.indentHeuristic
           Set this option to false to disable the default heuristics that
           shift diff hunk boundaries to make patches easier to read.

       diff.algorithm
           Choose a diff algorithm. The variants are as follows:

           default, myers
               The basic greedy diff algorithm. Currently, this is the
               default.

           minimal
               Spend extra time to make sure the smallest possible diff is
               produced.

           patience
               Use "patience diff" algorithm when generating patches.

           histogram
               This algorithm extends the patience algorithm to "support
               low-occurrence common elements".

       diff.wsErrorHighlight
           Highlight whitespace errors in the context, old or new lines of the
           diff. Multiple values are separated by comma, none resets previous
           values, default reset the list to new and all is a shorthand for
           old,new,context. The whitespace errors are colored with
           color.diff.whitespace. The command line option
           --ws-error-highlight=<kind> overrides this setting.

       diff.colorMoved
           If set to either a valid <mode> or a true value, moved lines in a
           diff are colored differently, for details of valid modes see
           --color-moved in git-diff(1). If simply set to true the default
           color mode will be used. When set to false, moved lines are not
           colored.

       diff.colorMovedWS
           When moved lines are colored using e.g. the diff.colorMoved
           setting, this option controls the <mode> how spaces are treated for
           details of valid modes see --color-moved-ws in git-diff(1).

       difftool.<tool>.path
           Override the path for the given tool. This is useful in case your
           tool is not in the PATH.

       difftool.<tool>.cmd
           Specify the command to invoke the specified diff tool. The
           specified command is evaluated in shell with the following
           variables available: LOCAL is set to the name of the temporary file
           containing the contents of the diff pre-image and REMOTE is set to
           the name of the temporary file containing the contents of the diff
           post-image.

       difftool.prompt
           Prompt before each invocation of the diff tool.

       fastimport.unpackLimit
           If the number of objects imported by git-fast-import(1) is below
           this limit, then the objects will be unpacked into loose object
           files. However if the number of imported objects equals or exceeds
           this limit then the pack will be stored as a pack. Storing the pack
           from a fast-import can make the import operation complete faster,
           especially on slow filesystems. If not set, the value of
           transfer.unpackLimit is used instead.

       feature.*
           The config settings that start with feature.  modify the defaults
           of a group of other config settings. These groups are created by
           the Git developer community as recommended defaults and are subject
           to change. In particular, new config options may be added with
           different defaults.

       feature.experimental
           Enable config options that are new to Git, and are being considered
           for future defaults. Config settings included here may be added or
           removed with each release, including minor version updates. These
           settings may have unintended interactions since they are so new.
           Please enable this setting if you are interested in providing
           feedback on experimental features. The new default values are:

           o   fetch.negotiationAlgorithm=skipping may improve fetch
               negotiation times by skipping more commits at a time, reducing
               the number of round trips.

           o   fetch.writeCommitGraph=true writes a commit-graph after every
               git fetch command that downloads a pack-file from a remote.
               Using the --split option, most executions will create a very
               small commit-graph file on top of the existing commit-graph
               file(s). Occasionally, these files will merge and the write may
               take longer. Having an updated commit-graph file helps
               performance of many Git commands, including git merge-base, git
               push -f, and git log --graph.

       feature.manyFiles
           Enable config options that optimize for repos with many files in
           the working directory. With many files, commands such as git status
           and git checkout may be slow and these new defaults improve
           performance:

           o   index.version=4 enables path-prefix compression in the index.

           o   core.untrackedCache=true enables the untracked cache. This
               setting assumes that mtime is working on your machine.

       fetch.recurseSubmodules
           This option controls whether git fetch (and the underlying fetch in
           git pull) will recursively fetch into populated submodules. This
           option can be set either to a boolean value or to on-demand.
           Setting it to a boolean changes the behavior of fetch and pull to
           recurse unconditionally into submodules when set to true or to not
           recurse at all when set to false. When set to on-demand, fetch and
           pull will only recurse into a populated submodule when its
           superproject retrieves a commit that updates the submodule's
           reference. Defaults to on-demand, or to the value of
           submodule.recurse if set.

       fetch.fsckObjects
           If it is set to true, git-fetch-pack will check all fetched
           objects. See transfer.fsckObjects for what's checked. Defaults to
           false. If not set, the value of transfer.fsckObjects is used
           instead.

       fetch.fsck.<msg-id>
           Acts like fsck.<msg-id>, but is used by git-fetch-pack(1) instead
           of git-fsck(1). See the fsck.<msg-id> documentation for details.

       fetch.fsck.skipList
           Acts like fsck.skipList, but is used by git-fetch-pack(1) instead
           of git-fsck(1). See the fsck.skipList documentation for details.

       fetch.unpackLimit
           If the number of objects fetched over the Git native transfer is
           below this limit, then the objects will be unpacked into loose
           object files. However if the number of received objects equals or
           exceeds this limit then the received pack will be stored as a pack,
           after adding any missing delta bases. Storing the pack from a push
           can make the push operation complete faster, especially on slow
           filesystems. If not set, the value of transfer.unpackLimit is used
           instead.

       fetch.prune
           If true, fetch will automatically behave as if the --prune option
           was given on the command line. See also remote.<name>.prune and the
           PRUNING section of git-fetch(1).

       fetch.pruneTags
           If true, fetch will automatically behave as if the
           refs/tags/*:refs/tags/* refspec was provided when pruning, if not
           set already. This allows for setting both this option and
           fetch.prune to maintain a 1=1 mapping to upstream refs. See also
           remote.<name>.pruneTags and the PRUNING section of git-fetch(1).

       fetch.output
           Control how ref update status is printed. Valid values are full and
           compact. Default value is full. See section OUTPUT in git-fetch(1)
           for detail.

       fetch.negotiationAlgorithm
           Control how information about the commits in the local repository
           is sent when negotiating the contents of the packfile to be sent by
           the server. Set to "skipping" to use an algorithm that skips
           commits in an effort to converge faster, but may result in a
           larger-than-necessary packfile; The default is "default" which
           instructs Git to use the default algorithm that never skips commits
           (unless the server has acknowledged it or one of its descendants).
           If feature.experimental is enabled, then this setting defaults to
           "skipping". Unknown values will cause git fetch to error out.

           See also the --negotiation-tip option for git-fetch(1).

       fetch.showForcedUpdates
           Set to false to enable --no-show-forced-updates in git-fetch(1) and
           git-pull(1) commands. Defaults to true.

       fetch.parallel
           Specifies the maximal number of fetch operations to be run in
           parallel at a time (submodules, or remotes when the --multiple
           option of git-fetch(1) is in effect).

           A value of 0 will give some reasonable default. If unset, it
           defaults to 1.

           For submodules, this setting can be overridden using the
           submodule.fetchJobs config setting.

       fetch.writeCommitGraph
           Set to true to write a commit-graph after every git fetch command
           that downloads a pack-file from a remote. Using the --split option,
           most executions will create a very small commit-graph file on top
           of the existing commit-graph file(s). Occasionally, these files
           will merge and the write may take longer. Having an updated
           commit-graph file helps performance of many Git commands, including
           git merge-base, git push -f, and git log --graph. Defaults to
           false, unless feature.experimental is true.

       format.attach
           Enable multipart/mixed attachments as the default for format-patch.
           The value can also be a double quoted string which will enable
           attachments as the default and set the value as the boundary. See
           the --attach option in git-format-patch(1).

       format.from
           Provides the default value for the --from option to format-patch.
           Accepts a boolean value, or a name and email address. If false,
           format-patch defaults to --no-from, using commit authors directly
           in the "From:" field of patch mails. If true, format-patch defaults
           to --from, using your committer identity in the "From:" field of
           patch mails and including a "From:" field in the body of the patch
           mail if different. If set to a non-boolean value, format-patch uses
           that value instead of your committer identity. Defaults to false.

       format.numbered
           A boolean which can enable or disable sequence numbers in patch
           subjects. It defaults to "auto" which enables it only if there is
           more than one patch. It can be enabled or disabled for all messages
           by setting it to "true" or "false". See --numbered option in git-
           format-patch(1).

       format.headers
           Additional email headers to include in a patch to be submitted by
           mail. See git-format-patch(1).

       format.to, format.cc
           Additional recipients to include in a patch to be submitted by
           mail. See the --to and --cc options in git-format-patch(1).

       format.subjectPrefix
           The default for format-patch is to output files with the [PATCH]
           subject prefix. Use this variable to change that prefix.

       format.coverFromDescription
           The default mode for format-patch to determine which parts of the
           cover letter will be populated using the branch's description. See
           the --cover-from-description option in git-format-patch(1).

       format.signature
           The default for format-patch is to output a signature containing
           the Git version number. Use this variable to change that default.
           Set this variable to the empty string ("") to suppress signature
           generation.

       format.signatureFile
           Works just like format.signature except the contents of the file
           specified by this variable will be used as the signature.

       format.suffix
           The default for format-patch is to output files with the suffix
           .patch. Use this variable to change that suffix (make sure to
           include the dot if you want it).

       format.encodeEmailHeaders
           Encode email headers that have non-ASCII characters with
           "Q-encoding" (described in RFC 2047) for email transmission.
           Defaults to true.

       format.pretty
           The default pretty format for log/show/whatchanged command, See
           git-log(1), git-show(1), git-whatchanged(1).

       format.thread
           The default threading style for git format-patch. Can be a boolean
           value, or shallow or deep.  shallow threading makes every mail a
           reply to the head of the series, where the head is chosen from the
           cover letter, the --in-reply-to, and the first patch mail, in this
           order.  deep threading makes every mail a reply to the previous
           one. A true boolean value is the same as shallow, and a false value
           disables threading.

       format.signOff
           A boolean value which lets you enable the -s/--signoff option of
           format-patch by default.  Note: Adding the Signed-off-by: line to a
           patch should be a conscious act and means that you certify you have
           the rights to submit this work under the same open source license.
           Please see the SubmittingPatches document for further discussion.

       format.coverLetter
           A boolean that controls whether to generate a cover-letter when
           format-patch is invoked, but in addition can be set to "auto", to
           generate a cover-letter only when there's more than one patch.
           Default is false.

       format.outputDirectory
           Set a custom directory to store the resulting files instead of the
           current working directory. All directory components will be
           created.

       format.useAutoBase
           A boolean value which lets you enable the --base=auto option of
           format-patch by default.

       format.notes
           Provides the default value for the --notes option to format-patch.
           Accepts a boolean value, or a ref which specifies where to get
           notes. If false, format-patch defaults to --no-notes. If true,
           format-patch defaults to --notes. If set to a non-boolean value,
           format-patch defaults to --notes=<ref>, where ref is the
           non-boolean value. Defaults to false.

           If one wishes to use the ref ref/notes/true, please use that
           literal instead.

           This configuration can be specified multiple times in order to
           allow multiple notes refs to be included. In that case, it will
           behave similarly to multiple --[no-]notes[=] options passed in.
           That is, a value of true will show the default notes, a value of
           <ref> will also show notes from that notes ref and a value of false
           will negate previous configurations and not show notes.

           For example,

               [format]
                       notes = true
                       notes = foo
                       notes = false
                       notes = bar

           will only show notes from refs/notes/bar.

       filter.<driver>.clean
           The command which is used to convert the content of a worktree file
           to a blob upon checkin. See gitattributes(5) for details.

       filter.<driver>.smudge
           The command which is used to convert the content of a blob object
           to a worktree file upon checkout. See gitattributes(5) for details.

       fsck.<msg-id>
           During fsck git may find issues with legacy data which wouldn't be
           generated by current versions of git, and which wouldn't be sent
           over the wire if transfer.fsckObjects was set. This feature is
           intended to support working with legacy repositories containing
           such data.

           Setting fsck.<msg-id> will be picked up by git-fsck(1), but to
           accept pushes of such data set receive.fsck.<msg-id> instead, or to
           clone or fetch it set fetch.fsck.<msg-id>.

           The rest of the documentation discusses fsck.*  for brevity, but
           the same applies for the corresponding receive.fsck.*  and
           fetch.<msg-id>.*. variables.

           Unlike variables like color.ui and core.editor the
           receive.fsck.<msg-id> and fetch.fsck.<msg-id> variables will not
           fall back on the fsck.<msg-id> configuration if they aren't set. To
           uniformly configure the same fsck settings in different
           circumstances all three of them they must all set to the same
           values.

           When fsck.<msg-id> is set, errors can be switched to warnings and
           vice versa by configuring the fsck.<msg-id> setting where the
           <msg-id> is the fsck message ID and the value is one of error, warn
           or ignore. For convenience, fsck prefixes the error/warning with
           the message ID, e.g. "missingEmail: invalid author/committer line -
           missing email" means that setting fsck.missingEmail = ignore will
           hide that issue.

           In general, it is better to enumerate existing objects with
           problems with fsck.skipList, instead of listing the kind of
           breakages these problematic objects share to be ignored, as doing
           the latter will allow new instances of the same breakages go
           unnoticed.

           Setting an unknown fsck.<msg-id> value will cause fsck to die, but
           doing the same for receive.fsck.<msg-id> and fetch.fsck.<msg-id>
           will only cause git to warn.

       fsck.skipList
           The path to a list of object names (i.e. one unabbreviated SHA-1
           per line) that are known to be broken in a non-fatal way and should
           be ignored. On versions of Git 2.20 and later comments (#), empty
           lines, and any leading and trailing whitespace is ignored.
           Everything but a SHA-1 per line will error out on older versions.

           This feature is useful when an established project should be
           accepted despite early commits containing errors that can be safely
           ignored such as invalid committer email addresses. Note: corrupt
           objects cannot be skipped with this setting.

           Like fsck.<msg-id> this variable has corresponding
           receive.fsck.skipList and fetch.fsck.skipList variants.

           Unlike variables like color.ui and core.editor the
           receive.fsck.skipList and fetch.fsck.skipList variables will not
           fall back on the fsck.skipList configuration if they aren't set. To
           uniformly configure the same fsck settings in different
           circumstances all three of them they must all set to the same
           values.

           Older versions of Git (before 2.20) documented that the object
           names list should be sorted. This was never a requirement, the
           object names could appear in any order, but when reading the list
           we tracked whether the list was sorted for the purposes of an
           internal binary search implementation, which could save itself some
           work with an already sorted list. Unless you had a humongous list
           there was no reason to go out of your way to pre-sort the list.
           After Git version 2.20 a hash implementation is used instead, so
           there's now no reason to pre-sort the list.

       gc.aggressiveDepth
           The depth parameter used in the delta compression algorithm used by
           git gc --aggressive. This defaults to 50, which is the default for
           the --depth option when --aggressive isn't in use.

           See the documentation for the --depth option in git-repack(1) for
           more details.

       gc.aggressiveWindow
           The window size parameter used in the delta compression algorithm
           used by git gc --aggressive. This defaults to 250, which is a much
           more aggressive window size than the default --window of 10.

           See the documentation for the --window option in git-repack(1) for
           more details.

       gc.auto
           When there are approximately more than this many loose objects in
           the repository, git gc --auto will pack them. Some Porcelain
           commands use this command to perform a light-weight garbage
           collection from time to time. The default value is 6700.

           Setting this to 0 disables not only automatic packing based on the
           number of loose objects, but any other heuristic git gc --auto will
           otherwise use to determine if there's work to do, such as
           gc.autoPackLimit.

       gc.autoPackLimit
           When there are more than this many packs that are not marked with
           *.keep file in the repository, git gc --auto consolidates them into
           one larger pack. The default value is 50. Setting this to 0
           disables it. Setting gc.auto to 0 will also disable this.

           See the gc.bigPackThreshold configuration variable below. When in
           use, it'll affect how the auto pack limit works.

       gc.autoDetach
           Make git gc --auto return immediately and run in background if the
           system supports it. Default is true.

       gc.bigPackThreshold
           If non-zero, all packs larger than this limit are kept when git gc
           is run. This is very similar to --keep-base-pack except that all
           packs that meet the threshold are kept, not just the base pack.
           Defaults to zero. Common unit suffixes of k, m, or g are supported.

           Note that if the number of kept packs is more than
           gc.autoPackLimit, this configuration variable is ignored, all packs
           except the base pack will be repacked. After this the number of
           packs should go below gc.autoPackLimit and gc.bigPackThreshold
           should be respected again.

           If the amount of memory estimated for git repack to run smoothly is
           not available and gc.bigPackThreshold is not set, the largest pack
           will also be excluded (this is the equivalent of running git gc
           with --keep-base-pack).

       gc.writeCommitGraph
           If true, then gc will rewrite the commit-graph file when git-gc(1)
           is run. When using git gc --auto the commit-graph will be updated
           if housekeeping is required. Default is true. See git-commit-
           graph(1) for details.

       gc.logExpiry
           If the file gc.log exists, then git gc --auto will print its
           content and exit with status zero instead of running unless that
           file is more than gc.logExpiry old. Default is "1.day". See
           gc.pruneExpire for more ways to specify its value.

       gc.packRefs
           Running git pack-refs in a repository renders it unclonable by Git
           versions prior to 1.5.1.2 over dumb transports such as HTTP. This
           variable determines whether git gc runs git pack-refs. This can be
           set to notbare to enable it within all non-bare repos or it can be
           set to a boolean value. The default is true.

       gc.pruneExpire
           When git gc is run, it will call prune --expire 2.weeks.ago.
           Override the grace period with this config variable. The value
           "now" may be used to disable this grace period and always prune
           unreachable objects immediately, or "never" may be used to suppress
           pruning. This feature helps prevent corruption when git gc runs
           concurrently with another process writing to the repository; see
           the "NOTES" section of git-gc(1).

       gc.worktreePruneExpire
           When git gc is run, it calls git worktree prune --expire
           3.months.ago. This config variable can be used to set a different
           grace period. The value "now" may be used to disable the grace
           period and prune $GIT_DIR/worktrees immediately, or "never" may be
           used to suppress pruning.

       gc.reflogExpire, gc.<pattern>.reflogExpire
           git reflog expire removes reflog entries older than this time;
           defaults to 90 days. The value "now" expires all entries
           immediately, and "never" suppresses expiration altogether. With
           "<pattern>" (e.g. "refs/stash") in the middle the setting applies
           only to the refs that match the <pattern>.

       gc.reflogExpireUnreachable, gc.<pattern>.reflogExpireUnreachable
           git reflog expire removes reflog entries older than this time and
           are not reachable from the current tip; defaults to 30 days. The
           value "now" expires all entries immediately, and "never" suppresses
           expiration altogether. With "<pattern>" (e.g. "refs/stash") in the
           middle, the setting applies only to the refs that match the
           <pattern>.

           These types of entries are generally created as a result of using
           git commit --amend or git rebase and are the commits prior to the
           amend or rebase occurring. Since these changes are not part of the
           current project most users will want to expire them sooner, which
           is why the default is more aggressive than gc.reflogExpire.

       gc.rerereResolved
           Records of conflicted merge you resolved earlier are kept for this
           many days when git rerere gc is run. You can also use more
           human-readable "1.month.ago", etc. The default is 60 days. See git-
           rerere(1).

       gc.rerereUnresolved
           Records of conflicted merge you have not resolved are kept for this
           many days when git rerere gc is run. You can also use more
           human-readable "1.month.ago", etc. The default is 15 days. See git-
           rerere(1).

       gitcvs.commitMsgAnnotation
           Append this string to each commit message. Set to empty string to
           disable this feature. Defaults to "via git-CVS emulator".

       gitcvs.enabled
           Whether the CVS server interface is enabled for this repository.
           See git-cvsserver(1).

       gitcvs.logFile
           Path to a log file where the CVS server interface well... logs
           various stuff. See git-cvsserver(1).

       gitcvs.usecrlfattr
           If true, the server will look up the end-of-line conversion
           attributes for files to determine the -k modes to use. If the
           attributes force Git to treat a file as text, the -k mode will be
           left blank so CVS clients will treat it as text. If they suppress
           text conversion, the file will be set with -kb mode, which
           suppresses any newline munging the client might otherwise do. If
           the attributes do not allow the file type to be determined, then
           gitcvs.allBinary is used. See gitattributes(5).

       gitcvs.allBinary
           This is used if gitcvs.usecrlfattr does not resolve the correct -kb
           mode to use. If true, all unresolved files are sent to the client
           in mode -kb. This causes the client to treat them as binary files,
           which suppresses any newline munging it otherwise might do.
           Alternatively, if it is set to "guess", then the contents of the
           file are examined to decide if it is binary, similar to
           core.autocrlf.

       gitcvs.dbName
           Database used by git-cvsserver to cache revision information
           derived from the Git repository. The exact meaning depends on the
           used database driver, for SQLite (which is the default driver) this
           is a filename. Supports variable substitution (see git-cvsserver(1)
           for details). May not contain semicolons (;). Default:
           %Ggitcvs.%m.sqlite

       gitcvs.dbDriver
           Used Perl DBI driver. You can specify any available driver for this
           here, but it might not work. git-cvsserver is tested with
           DBD::SQLite, reported to work with DBD::Pg, and reported not to
           work with DBD::mysql. Experimental feature. May not contain double
           colons (:). Default: SQLite. See git-cvsserver(1).

       gitcvs.dbUser, gitcvs.dbPass
           Database user and password. Only useful if setting gitcvs.dbDriver,
           since SQLite has no concept of database users and/or passwords.
           gitcvs.dbUser supports variable substitution (see git-cvsserver(1)
           for details).

       gitcvs.dbTableNamePrefix
           Database table name prefix. Prepended to the names of any database
           tables used, allowing a single database to be used for several
           repositories. Supports variable substitution (see git-cvsserver(1)
           for details). Any non-alphabetic characters will be replaced with
           underscores.

       All gitcvs variables except for gitcvs.usecrlfattr and gitcvs.allBinary
       can also be specified as gitcvs.<access_method>.<varname> (where
       access_method is one of "ext" and "pserver") to make them apply only
       for the given access method.

       gitweb.category, gitweb.description, gitweb.owner, gitweb.url
           See gitweb(1) for description.

       gitweb.avatar, gitweb.blame, gitweb.grep, gitweb.highlight,
       gitweb.patches, gitweb.pickaxe, gitweb.remote_heads, gitweb.showSizes,
       gitweb.snapshot
           See gitweb.conf(5) for description.

       grep.lineNumber
           If set to true, enable -n option by default.

       grep.column
           If set to true, enable the --column option by default.

       grep.patternType
           Set the default matching behavior. Using a value of basic,
           extended, fixed, or perl will enable the --basic-regexp,
           --extended-regexp, --fixed-strings, or --perl-regexp option
           accordingly, while the value default will return to the default
           matching behavior.

       grep.extendedRegexp
           If set to true, enable --extended-regexp option by default. This
           option is ignored when the grep.patternType option is set to a
           value other than default.

       grep.threads
           Number of grep worker threads to use. See grep.threads in git-
           grep(1) for more information.

       grep.fallbackToNoIndex
           If set to true, fall back to git grep --no-index if git grep is
           executed outside of a git repository. Defaults to false.

       gpg.program
           Use this custom program instead of "gpg" found on $PATH when making
           or verifying a PGP signature. The program must support the same
           command-line interface as GPG, namely, to verify a detached
           signature, "gpg --verify $signature - <$file" is run, and the
           program is expected to signal a good signature by exiting with code
           0, and to generate an ASCII-armored detached signature, the
           standard input of "gpg -bsau $key" is fed with the contents to be
           signed, and the program is expected to send the result to its
           standard output.

       gpg.format
           Specifies which key format to use when signing with --gpg-sign.
           Default is "openpgp" and another possible value is "x509".

       gpg.<format>.program
           Use this to customize the program used for the signing format you
           chose. (see gpg.program and gpg.format) gpg.program can still be
           used as a legacy synonym for gpg.openpgp.program. The default value
           for gpg.x509.program is "gpgsm".

       gpg.minTrustLevel
           Specifies a minimum trust level for signature verification. If this
           option is unset, then signature verification for merge operations
           require a key with at least marginal trust. Other operations that
           perform signature verification require a key with at least
           undefined trust. Setting this option overrides the required
           trust-level for all operations. Supported values, in increasing
           order of significance:

           o   undefined

           o   never

           o   marginal

           o   fully

           o   ultimate

       gui.commitMsgWidth
           Defines how wide the commit message window is in the git-gui(1).
           "75" is the default.

       gui.diffContext
           Specifies how many context lines should be used in calls to diff
           made by the git-gui(1). The default is "5".

       gui.displayUntracked
           Determines if git-gui(1) shows untracked files in the file list.
           The default is "true".

       gui.encoding
           Specifies the default encoding to use for displaying of file
           contents in git-gui(1) and gitk(1). It can be overridden by setting
           the encoding attribute for relevant files (see gitattributes(5)).
           If this option is not set, the tools default to the locale
           encoding.

       gui.matchTrackingBranch
           Determines if new branches created with git-gui(1) should default
           to tracking remote branches with matching names or not. Default:
           "false".

       gui.newBranchTemplate
           Is used as suggested name when creating new branches using the git-
           gui(1).

       gui.pruneDuringFetch
           "true" if git-gui(1) should prune remote-tracking branches when
           performing a fetch. The default value is "false".

       gui.trustmtime
           Determines if git-gui(1) should trust the file modification
           timestamp or not. By default the timestamps are not trusted.

       gui.spellingDictionary
           Specifies the dictionary used for spell checking commit messages in
           the git-gui(1). When set to "none" spell checking is turned off.

       gui.fastCopyBlame
           If true, git gui blame uses -C instead of -C -C for original
           location detection. It makes blame significantly faster on huge
           repositories at the expense of less thorough copy detection.

       gui.copyBlameThreshold
           Specifies the threshold to use in git gui blame original location
           detection, measured in alphanumeric characters. See the git-
           blame(1) manual for more information on copy detection.

       gui.blamehistoryctx
           Specifies the radius of history context in days to show in gitk(1)
           for the selected commit, when the Show History Context menu item is
           invoked from git gui blame. If this variable is set to zero, the
           whole history is shown.

       guitool.<name>.cmd
           Specifies the shell command line to execute when the corresponding
           item of the git-gui(1) Tools menu is invoked. This option is
           mandatory for every tool. The command is executed from the root of
           the working directory, and in the environment it receives the name
           of the tool as GIT_GUITOOL, the name of the currently selected file
           as FILENAME, and the name of the current branch as CUR_BRANCH (if
           the head is detached, CUR_BRANCH is empty).

       guitool.<name>.needsFile
           Run the tool only if a diff is selected in the GUI. It guarantees
           that FILENAME is not empty.

       guitool.<name>.noConsole
           Run the command silently, without creating a window to display its
           output.

       guitool.<name>.noRescan
           Don't rescan the working directory for changes after the tool
           finishes execution.

       guitool.<name>.confirm
           Show a confirmation dialog before actually running the tool.

       guitool.<name>.argPrompt
           Request a string argument from the user, and pass it to the tool
           through the ARGS environment variable. Since requesting an argument
           implies confirmation, the confirm option has no effect if this is
           enabled. If the option is set to true, yes, or 1, the dialog uses a
           built-in generic prompt; otherwise the exact value of the variable
           is used.

       guitool.<name>.revPrompt
           Request a single valid revision from the user, and set the REVISION
           environment variable. In other aspects this option is similar to
           argPrompt, and can be used together with it.

       guitool.<name>.revUnmerged
           Show only unmerged branches in the revPrompt subdialog. This is
           useful for tools similar to merge or rebase, but not for things
           like checkout or reset.

       guitool.<name>.title
           Specifies the title to use for the prompt dialog. The default is
           the tool name.

       guitool.<name>.prompt
           Specifies the general prompt string to display at the top of the
           dialog, before subsections for argPrompt and revPrompt. The default
           value includes the actual command.

       help.browser
           Specify the browser that will be used to display help in the web
           format. See git-help(1).

       help.format
           Override the default help format used by git-help(1). Values man,
           info, web and html are supported.  man is the default.  web and
           html are the same.

       help.autoCorrect
           Automatically correct and execute mistyped commands after waiting
           for the given number of deciseconds (0.1 sec). If more than one
           command can be deduced from the entered text, nothing will be
           executed. If the value of this option is negative, the corrected
           command will be executed immediately. If the value is 0 - the
           command will be just shown but not executed. This is the default.

       help.htmlPath
           Specify the path where the HTML documentation resides. File system
           paths and URLs are supported. HTML pages will be prefixed with this
           path when help is displayed in the web format. This defaults to the
           documentation path of your Git installation.

       http.proxy
           Override the HTTP proxy, normally configured using the http_proxy,
           https_proxy, and all_proxy environment variables (see curl(1)). In
           addition to the syntax understood by curl, it is possible to
           specify a proxy string with a user name but no password, in which
           case git will attempt to acquire one in the same way it does for
           other credentials. See gitcredentials(7) for more information. The
           syntax thus is [protocol://][user[:password]@]proxyhost[:port].
           This can be overridden on a per-remote basis; see
           remote.<name>.proxy

       http.proxyAuthMethod
           Set the method with which to authenticate against the HTTP proxy.
           This only takes effect if the configured proxy string contains a
           user name part (i.e. is of the form user@host or user@host:port).
           This can be overridden on a per-remote basis; see
           remote.<name>.proxyAuthMethod. Both can be overridden by the
           GIT_HTTP_PROXY_AUTHMETHOD environment variable. Possible values
           are:

           o   anyauth - Automatically pick a suitable authentication method.
               It is assumed that the proxy answers an unauthenticated request
               with a 407 status code and one or more Proxy-authenticate
               headers with supported authentication methods. This is the
               default.

           o   basic - HTTP Basic authentication

           o   digest - HTTP Digest authentication; this prevents the password
               from being transmitted to the proxy in clear text

           o   negotiate - GSS-Negotiate authentication (compare the
               --negotiate option of curl(1))

           o   ntlm - NTLM authentication (compare the --ntlm option of
               curl(1))

       http.proxySSLCert
           The pathname of a file that stores a client certificate to use to
           authenticate with an HTTPS proxy. Can be overridden by the
           GIT_PROXY_SSL_CERT environment variable.

       http.proxySSLKey
           The pathname of a file that stores a private key to use to
           authenticate with an HTTPS proxy. Can be overridden by the
           GIT_PROXY_SSL_KEY environment variable.

       http.proxySSLCertPasswordProtected
           Enable Git's password prompt for the proxy SSL certificate.
           Otherwise OpenSSL will prompt the user, possibly many times, if the
           certificate or private key is encrypted. Can be overriden by the
           GIT_PROXY_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.proxySSLCAInfo
           Pathname to the file containing the certificate bundle that should
           be used to verify the proxy with when using an HTTPS proxy. Can be
           overriden by the GIT_PROXY_SSL_CAINFO environment variable.

       http.emptyAuth
           Attempt authentication without seeking a username or password. This
           can be used to attempt GSS-Negotiate authentication without
           specifying a username in the URL, as libcurl normally requires a
           username for authentication.

       http.delegation
           Control GSSAPI credential delegation. The delegation is disabled by
           default in libcurl since version 7.21.7. Set parameter to tell the
           server what it is allowed to delegate when it comes to user
           credentials. Used with GSS/kerberos. Possible values are:

           o   none - Don't allow any delegation.

           o   policy - Delegates if and only if the OK-AS-DELEGATE flag is
               set in the Kerberos service ticket, which is a matter of realm
               policy.

           o   always - Unconditionally allow the server to delegate.

       http.extraHeader
           Pass an additional HTTP header when communicating with a server. If
           more than one such entry exists, all of them are added as extra
           headers. To allow overriding the settings inherited from the system
           config, an empty value will reset the extra headers to the empty
           list.

       http.cookieFile
           The pathname of a file containing previously stored cookie lines,
           which should be used in the Git http session, if they match the
           server. The file format of the file to read cookies from should be
           plain HTTP headers or the Netscape/Mozilla cookie file format (see
           curl(1)). NOTE that the file specified with http.cookieFile is used
           only as input unless http.saveCookies is set.

       http.saveCookies
           If set, store cookies received during requests to the file
           specified by http.cookieFile. Has no effect if http.cookieFile is
           unset.

       http.version
           Use the specified HTTP protocol version when communicating with a
           server. If you want to force the default. The available and default
           version depend on libcurl. Currently the possible values of this
           option are:

           o   HTTP/2

           o   HTTP/1.1

       http.sslVersion
           The SSL version to use when negotiating an SSL connection, if you
           want to force the default. The available and default version depend
           on whether libcurl was built against NSS or OpenSSL and the
           particular configuration of the crypto library in use. Internally
           this sets the CURLOPT_SSL_VERSION option; see the libcurl
           documentation for more details on the format of this option and for
           the ssl version supported. Currently the possible values of this
           option are:

           o   sslv2

           o   sslv3

           o   tlsv1

           o   tlsv1.0

           o   tlsv1.1

           o   tlsv1.2

           o   tlsv1.3

           Can be overridden by the GIT_SSL_VERSION environment variable. To
           force git to use libcurl's default ssl version and ignore any
           explicit http.sslversion option, set GIT_SSL_VERSION to the empty
           string.

       http.sslCipherList
           A list of SSL ciphers to use when negotiating an SSL connection.
           The available ciphers depend on whether libcurl was built against
           NSS or OpenSSL and the particular configuration of the crypto
           library in use. Internally this sets the CURLOPT_SSL_CIPHER_LIST
           option; see the libcurl documentation for more details on the
           format of this list.

           Can be overridden by the GIT_SSL_CIPHER_LIST environment variable.
           To force git to use libcurl's default cipher list and ignore any
           explicit http.sslCipherList option, set GIT_SSL_CIPHER_LIST to the
           empty string.

       http.sslVerify
           Whether to verify the SSL certificate when fetching or pushing over
           HTTPS. Defaults to true. Can be overridden by the GIT_SSL_NO_VERIFY
           environment variable.

       http.sslCert
           File containing the SSL certificate when fetching or pushing over
           HTTPS. Can be overridden by the GIT_SSL_CERT environment variable.

       http.sslKey
           File containing the SSL private key when fetching or pushing over
           HTTPS. Can be overridden by the GIT_SSL_KEY environment variable.

       http.sslCertPasswordProtected
           Enable Git's password prompt for the SSL certificate. Otherwise
           OpenSSL will prompt the user, possibly many times, if the
           certificate or private key is encrypted. Can be overridden by the
           GIT_SSL_CERT_PASSWORD_PROTECTED environment variable.

       http.sslCAInfo
           File containing the certificates to verify the peer with when
           fetching or pushing over HTTPS. Can be overridden by the
           GIT_SSL_CAINFO environment variable.

       http.sslCAPath
           Path containing files with the CA certificates to verify the peer
           with when fetching or pushing over HTTPS. Can be overridden by the
           GIT_SSL_CAPATH environment variable.

       http.sslBackend
           Name of the SSL backend to use (e.g. "openssl" or "schannel"). This
           option is ignored if cURL lacks support for choosing the SSL
           backend at runtime.

       http.schannelCheckRevoke
           Used to enforce or disable certificate revocation checks in cURL
           when http.sslBackend is set to "schannel". Defaults to true if
           unset. Only necessary to disable this if Git consistently errors
           and the message is about checking the revocation status of a
           certificate. This option is ignored if cURL lacks support for
           setting the relevant SSL option at runtime.

       http.schannelUseSSLCAInfo
           As of cURL v7.60.0, the Secure Channel backend can use the
           certificate bundle provided via http.sslCAInfo, but that would
           override the Windows Certificate Store. Since this is not desirable
           by default, Git will tell cURL not to use that bundle by default
           when the schannel backend was configured via http.sslBackend,
           unless http.schannelUseSSLCAInfo overrides this behavior.

       http.pinnedpubkey
           Public key of the https service. It may either be the filename of a
           PEM or DER encoded public key file or a string starting with
           sha256// followed by the base64 encoded sha256 hash of the public
           key. See also libcurl CURLOPT_PINNEDPUBLICKEY. git will exit with
           an error if this option is set but not supported by cURL.

       http.sslTry
           Attempt to use AUTH SSL/TLS and encrypted data transfers when
           connecting via regular FTP protocol. This might be needed if the
           FTP server requires it for security reasons or you wish to connect
           securely whenever remote FTP server supports it. Default is false
           since it might trigger certificate verification errors on
           misconfigured servers.

       http.maxRequests
           How many HTTP requests to launch in parallel. Can be overridden by
           the GIT_HTTP_MAX_REQUESTS environment variable. Default is 5.

       http.minSessions
           The number of curl sessions (counted across slots) to be kept
           across requests. They will not be ended with curl_easy_cleanup()
           until http_cleanup() is invoked. If USE_CURL_MULTI is not defined,
           this value will be capped at 1. Defaults to 1.

       http.postBuffer
           Maximum size in bytes of the buffer used by smart HTTP transports
           when POSTing data to the remote system. For requests larger than
           this buffer size, HTTP/1.1 and Transfer-Encoding: chunked is used
           to avoid creating a massive pack file locally. Default is 1 MiB,
           which is sufficient for most requests.

           Note that raising this limit is only effective for disabling
           chunked transfer encoding and therefore should be used only where
           the remote server or a proxy only supports HTTP/1.0 or is
           noncompliant with the HTTP standard. Raising this is not, in
           general, an effective solution for most push problems, but can
           increase memory consumption significantly since the entire buffer
           is allocated even for small pushes.

       http.lowSpeedLimit, http.lowSpeedTime
           If the HTTP transfer speed is less than http.lowSpeedLimit for
           longer than http.lowSpeedTime seconds, the transfer is aborted. Can
           be overridden by the GIT_HTTP_LOW_SPEED_LIMIT and
           GIT_HTTP_LOW_SPEED_TIME environment variables.

       http.noEPSV
           A boolean which disables using of EPSV ftp command by curl. This
           can helpful with some "poor" ftp servers which don't support EPSV
           mode. Can be overridden by the GIT_CURL_FTP_NO_EPSV environment
           variable. Default is false (curl will use EPSV).

       http.userAgent
           The HTTP USER_AGENT string presented to an HTTP server. The default
           value represents the version of the client Git such as git/1.7.1.
           This option allows you to override this value to a more common
           value such as Mozilla/4.0. This may be necessary, for instance, if
           connecting through a firewall that restricts HTTP connections to a
           set of common USER_AGENT strings (but not including those like
           git/1.7.1). Can be overridden by the GIT_HTTP_USER_AGENT
           environment variable.

       http.followRedirects
           Whether git should follow HTTP redirects. If set to true, git will
           transparently follow any redirect issued by a server it encounters.
           If set to false, git will treat all redirects as errors. If set to
           initial, git will follow redirects only for the initial request to
           a remote, but not for subsequent follow-up HTTP requests. Since git
           uses the redirected URL as the base for the follow-up requests,
           this is generally sufficient. The default is initial.

       http.<url>.*
           Any of the http.* options above can be applied selectively to some
           URLs. For a config key to match a URL, each element of the config
           key is compared to that of the URL, in the following order:

            1. Scheme (e.g., https in https://example.com/). This field must
               match exactly between the config key and the URL.

            2. Host/domain name (e.g., example.com in https://example.com/).
               This field must match between the config key and the URL. It is
               possible to specify a * as part of the host name to match all
               subdomains at this level.  https://*.example.com/ for example
               would match https://foo.example.com/, but not
               https://foo.bar.example.com/.

            3. Port number (e.g., 8080 in http://example.com:8080/). This
               field must match exactly between the config key and the URL.
               Omitted port numbers are automatically converted to the correct
               default for the scheme before matching.

            4. Path (e.g., repo.git in https://example.com/repo.git). The path
               field of the config key must match the path field of the URL
               either exactly or as a prefix of slash-delimited path elements.
               This means a config key with path foo/ matches URL path
               foo/bar. A prefix can only match on a slash (/) boundary.
               Longer matches take precedence (so a config key with path
               foo/bar is a better match to URL path foo/bar than a config key
               with just path foo/).

            5. User name (e.g., user in https://user@example.com/repo.git). If
               the config key has a user name it must match the user name in
               the URL exactly. If the config key does not have a user name,
               that config key will match a URL with any user name (including
               none), but at a lower precedence than a config key with a user
               name.

           The list above is ordered by decreasing precedence; a URL that
           matches a config key's path is preferred to one that matches its
           user name. For example, if the URL is
           https://user@example.com/foo/bar a config key match of
           https://example.com/foo will be preferred over a config key match
           of https://user@example.com.

           All URLs are normalized before attempting any matching (the
           password part, if embedded in the URL, is always ignored for
           matching purposes) so that equivalent URLs that are simply spelled
           differently will match properly. Environment variable settings
           always override any matches. The URLs that are matched against are
           those given directly to Git commands. This means any URLs visited
           as a result of a redirection do not participate in matching.

       i18n.commitEncoding
           Character encoding the commit messages are stored in; Git itself
           does not care per se, but this information is necessary e.g. when
           importing commits from emails or in the gitk graphical history
           browser (and possibly at other places in the future or in other
           porcelains). See e.g.  git-mailinfo(1). Defaults to utf-8.

       i18n.logOutputEncoding
           Character encoding the commit messages are converted to when
           running git log and friends.

       imap.folder
           The folder to drop the mails into, which is typically the Drafts
           folder. For example: "INBOX.Drafts", "INBOX/Drafts" or
           "[Gmail]/Drafts". Required.

       imap.tunnel
           Command used to setup a tunnel to the IMAP server through which
           commands will be piped instead of using a direct network connection
           to the server. Required when imap.host is not set.

       imap.host
           A URL identifying the server. Use an imap:// prefix for non-secure
           connections and an imaps:// prefix for secure connections. Ignored
           when imap.tunnel is set, but required otherwise.

       imap.user
           The username to use when logging in to the server.

       imap.pass
           The password to use when logging in to the server.

       imap.port
           An integer port number to connect to on the server. Defaults to 143
           for imap:// hosts and 993 for imaps:// hosts. Ignored when
           imap.tunnel is set.

       imap.sslverify
           A boolean to enable/disable verification of the server certificate
           used by the SSL/TLS connection. Default is true. Ignored when
           imap.tunnel is set.

       imap.preformattedHTML
           A boolean to enable/disable the use of html encoding when sending a
           patch. An html encoded patch will be bracketed with <pre> and have
           a content type of text/html. Ironically, enabling this option
           causes Thunderbird to send the patch as a plain/text, format=fixed
           email. Default is false.

       imap.authMethod
           Specify authenticate method for authentication with IMAP server. If
           Git was built with the NO_CURL option, or if your curl version is
           older than 7.34.0, or if you're running git-imap-send with the
           --no-curl option, the only supported method is CRAM-MD5. If this is
           not set then git imap-send uses the basic IMAP plaintext LOGIN
           command.

       index.recordEndOfIndexEntries
           Specifies whether the index file should include an "End Of Index
           Entry" section. This reduces index load time on multiprocessor
           machines but produces a message "ignoring EOIE extension" when
           reading the index using Git versions before 2.20. Defaults to true
           if index.threads has been explicitly enabled, false otherwise.

       index.recordOffsetTable
           Specifies whether the index file should include an "Index Entry
           Offset Table" section. This reduces index load time on
           multiprocessor machines but produces a message "ignoring IEOT
           extension" when reading the index using Git versions before 2.20.
           Defaults to true if index.threads has been explicitly enabled,
           false otherwise.

       index.threads
           Specifies the number of threads to spawn when loading the index.
           This is meant to reduce index load time on multiprocessor machines.
           Specifying 0 or true will cause Git to auto-detect the number of
           CPU's and set the number of threads accordingly. Specifying 1 or
           false will disable multithreading. Defaults to true.

       index.version
           Specify the version with which new index files should be
           initialized. This does not affect existing repositories. If
           feature.manyFiles is enabled, then the default is 4.

       init.templateDir
           Specify the directory from which templates will be copied. (See the
           "TEMPLATE DIRECTORY" section of git-init(1).)

       instaweb.browser
           Specify the program that will be used to browse your working
           repository in gitweb. See git-instaweb(1).

       instaweb.httpd
           The HTTP daemon command-line to start gitweb on your working
           repository. See git-instaweb(1).

       instaweb.local
           If true the web server started by git-instaweb(1) will be bound to
           the local IP (127.0.0.1).

       instaweb.modulePath
           The default module path for git-instaweb(1) to use instead of
           /usr/lib/apache2/modules. Only used if httpd is Apache.

       instaweb.port
           The port number to bind the gitweb httpd to. See git-instaweb(1).

       interactive.singleKey
           In interactive commands, allow the user to provide one-letter input
           with a single key (i.e., without hitting enter). Currently this is
           used by the --patch mode of git-add(1), git-checkout(1), git-
           restore(1), git-commit(1), git-reset(1), and git-stash(1). Note
           that this setting is silently ignored if portable keystroke input
           is not available; requires the Perl module Term::ReadKey.

       interactive.diffFilter
           When an interactive command (such as git add --patch) shows a
           colorized diff, git will pipe the diff through the shell command
           defined by this configuration variable. The command may mark up the
           diff further for human consumption, provided that it retains a
           one-to-one correspondence with the lines in the original diff.
           Defaults to disabled (no filtering).

       log.abbrevCommit
           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
           assume --abbrev-commit. You may override this option with
           --no-abbrev-commit.

       log.date
           Set the default date-time mode for the log command. Setting a value
           for log.date is similar to using git log's --date option. See git-
           log(1) for details.

       log.decorate
           Print out the ref names of any commits that are shown by the log
           command. If short is specified, the ref name prefixes refs/heads/,
           refs/tags/ and refs/remotes/ will not be printed. If full is
           specified, the full ref name (including prefix) will be printed. If
           auto is specified, then if the output is going to a terminal, the
           ref names are shown as if short were given, otherwise no ref names
           are shown. This is the same as the --decorate option of the git
           log.

       log.excludeDecoration
           Exclude the specified patterns from the log decorations. This is
           similar to the --decorate-refs-exclude command-line option, but the
           config option can be overridden by the --decorate-refs option.

       log.follow
           If true, git log will act as if the --follow option was used when a
           single <path> is given. This has the same limitations as --follow,
           i.e. it cannot be used to follow multiple files and does not work
           well on non-linear history.

       log.graphColors
           A list of colors, separated by commas, that can be used to draw
           history lines in git log --graph.

       log.showRoot
           If true, the initial commit will be shown as a big creation event.
           This is equivalent to a diff against an empty tree. Tools like git-
           log(1) or git-whatchanged(1), which normally hide the root commit
           will now show it. True by default.

       log.showSignature
           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
           assume --show-signature.

       log.mailmap
           If true, makes git-log(1), git-show(1), and git-whatchanged(1)
           assume --use-mailmap, otherwise assume --no-use-mailmap. True by
           default.

       mailinfo.scissors
           If true, makes git-mailinfo(1) (and therefore git-am(1)) act by
           default as if the --scissors option was provided on the
           command-line. When active, this features removes everything from
           the message body before a scissors line (i.e. consisting mainly of
           ">8", "8<" and "-").

       mailmap.file
           The location of an augmenting mailmap file. The default mailmap,
           located in the root of the repository, is loaded first, then the
           mailmap file pointed to by this variable. The location of the
           mailmap file may be in a repository subdirectory, or somewhere
           outside of the repository itself. See git-shortlog(1) and git-
           blame(1).

       mailmap.blob
           Like mailmap.file, but consider the value as a reference to a blob
           in the repository. If both mailmap.file and mailmap.blob are given,
           both are parsed, with entries from mailmap.file taking precedence.
           In a bare repository, this defaults to HEAD:.mailmap. In a non-bare
           repository, it defaults to empty.

       man.viewer
           Specify the programs that may be used to display help in the man
           format. See git-help(1).

       man.<tool>.cmd
           Specify the command to invoke the specified man viewer. The
           specified command is evaluated in shell with the man page passed as
           argument. (See git-help(1).)

       man.<tool>.path
           Override the path for the given tool that may be used to display
           help in the man format. See git-help(1).

       merge.conflictStyle
           Specify the style in which conflicted hunks are written out to
           working tree files upon merge. The default is "merge", which shows
           a <<<<<<< conflict marker, changes made by one side, a =======
           marker, changes made by the other side, and then a >>>>>>> marker.
           An alternate style, "diff3", adds a ||||||| marker and the original
           text before the ======= marker.

       merge.defaultToUpstream
           If merge is called without any commit argument, merge the upstream
           branches configured for the current branch by using their last
           observed values stored in their remote-tracking branches. The
           values of the branch.<current branch>.merge that name the branches
           at the remote named by branch.<current branch>.remote are
           consulted, and then they are mapped via remote.<remote>.fetch to
           their corresponding remote-tracking branches, and the tips of these
           tracking branches are merged.

       merge.ff
           By default, Git does not create an extra merge commit when merging
           a commit that is a descendant of the current commit. Instead, the
           tip of the current branch is fast-forwarded. When set to false,
           this variable tells Git to create an extra merge commit in such a
           case (equivalent to giving the --no-ff option from the command
           line). When set to only, only such fast-forward merges are allowed
           (equivalent to giving the --ff-only option from the command line).

       merge.verifySignatures
           If true, this is equivalent to the --verify-signatures command line
           option. See git-merge(1) for details.

       merge.branchdesc
           In addition to branch names, populate the log message with the
           branch description text associated with them. Defaults to false.

       merge.log
           In addition to branch names, populate the log message with at most
           the specified number of one-line descriptions from the actual
           commits that are being merged. Defaults to false, and true is a
           synonym for 20.

       merge.renameLimit
           The number of files to consider when performing rename detection
           during a merge; if not specified, defaults to the value of
           diff.renameLimit. This setting has no effect if rename detection is
           turned off.

       merge.renames
           Whether Git detects renames. If set to "false", rename detection is
           disabled. If set to "true", basic rename detection is enabled.
           Defaults to the value of diff.renames.

       merge.directoryRenames
           Whether Git detects directory renames, affecting what happens at
           merge time to new files added to a directory on one side of history
           when that directory was renamed on the other side of history. If
           merge.directoryRenames is set to "false", directory rename
           detection is disabled, meaning that such new files will be left
           behind in the old directory. If set to "true", directory rename
           detection is enabled, meaning that such new files will be moved
           into the new directory. If set to "conflict", a conflict will be
           reported for such paths. If merge.renames is false,
           merge.directoryRenames is ignored and treated as false. Defaults to
           "conflict".

       merge.renormalize
           Tell Git that canonical representation of files in the repository
           has changed over time (e.g. earlier commits record text files with
           CRLF line endings, but recent ones use LF line endings). In such a
           repository, Git can convert the data recorded in commits to a
           canonical form before performing a merge to reduce unnecessary
           conflicts. For more information, see section "Merging branches with
           differing checkin/checkout attributes" in gitattributes(5).

       merge.stat
           Whether to print the diffstat between ORIG_HEAD and the merge
           result at the end of the merge. True by default.

       merge.autoStash
           When set to true, automatically create a temporary stash entry
           before the operation begins, and apply it after the operation ends.
           This means that you can run merge on a dirty worktree. However, use
           with care: the final stash application after a successful merge
           might result in non-trivial conflicts. This option can be
           overridden by the --no-autostash and --autostash options of git-
           merge(1). Defaults to false.

       merge.tool
           Controls which merge tool is used by git-mergetool(1). The list
           below shows the valid built-in values. Any other value is treated
           as a custom merge tool and requires that a corresponding
           mergetool.<tool>.cmd variable is defined.

       merge.guitool
           Controls which merge tool is used by git-mergetool(1) when the
           -g/--gui flag is specified. The list below shows the valid built-in
           values. Any other value is treated as a custom merge tool and
           requires that a corresponding mergetool.<guitool>.cmd variable is
           defined.

       merge.verbosity
           Controls the amount of output shown by the recursive merge
           strategy. Level 0 outputs nothing except a final error message if
           conflicts were detected. Level 1 outputs only conflicts, 2 outputs
           conflicts and file changes. Level 5 and above outputs debugging
           information. The default is level 2. Can be overridden by the
           GIT_MERGE_VERBOSITY environment variable.

       merge.<driver>.name
           Defines a human-readable name for a custom low-level merge driver.
           See gitattributes(5) for details.

       merge.<driver>.driver
           Defines the command that implements a custom low-level merge
           driver. See gitattributes(5) for details.

       merge.<driver>.recursive
           Names a low-level merge driver to be used when performing an
           internal merge between common ancestors. See gitattributes(5) for
           details.

       mergetool.<tool>.path
           Override the path for the given tool. This is useful in case your
           tool is not in the PATH.

       mergetool.<tool>.cmd
           Specify the command to invoke the specified merge tool. The
           specified command is evaluated in shell with the following
           variables available: BASE is the name of a temporary file
           containing the common base of the files to be merged, if available;
           LOCAL is the name of a temporary file containing the contents of
           the file on the current branch; REMOTE is the name of a temporary
           file containing the contents of the file from the branch being
           merged; MERGED contains the name of the file to which the merge
           tool should write the results of a successful merge.

       mergetool.<tool>.trustExitCode
           For a custom merge command, specify whether the exit code of the
           merge command can be used to determine whether the merge was
           successful. If this is not set to true then the merge target file
           timestamp is checked and the merge assumed to have been successful
           if the file has been updated, otherwise the user is prompted to
           indicate the success of the merge.

       mergetool.meld.hasOutput
           Older versions of meld do not support the --output option. Git will
           attempt to detect whether meld supports --output by inspecting the
           output of meld --help. Configuring mergetool.meld.hasOutput will
           make Git skip these checks and use the configured value instead.
           Setting mergetool.meld.hasOutput to true tells Git to
           unconditionally use the --output option, and false avoids using
           --output.

       mergetool.keepBackup
           After performing a merge, the original file with conflict markers
           can be saved as a file with a .orig extension. If this variable is
           set to false then this file is not preserved. Defaults to true
           (i.e. keep the backup files).

       mergetool.keepTemporaries
           When invoking a custom merge tool, Git uses a set of temporary
           files to pass to the tool. If the tool returns an error and this
           variable is set to true, then these temporary files will be
           preserved, otherwise they will be removed after the tool has
           exited. Defaults to false.

       mergetool.writeToTemp
           Git writes temporary BASE, LOCAL, and REMOTE versions of
           conflicting files in the worktree by default. Git will attempt to
           use a temporary directory for these files when set true. Defaults
           to false.

       mergetool.prompt
           Prompt before each invocation of the merge resolution program.

       notes.mergeStrategy
           Which merge strategy to choose by default when resolving notes
           conflicts. Must be one of manual, ours, theirs, union, or
           cat_sort_uniq. Defaults to manual. See "NOTES MERGE STRATEGIES"
           section of git-notes(1) for more information on each strategy.

       notes.<name>.mergeStrategy
           Which merge strategy to choose when doing a notes merge into
           refs/notes/<name>. This overrides the more general
           "notes.mergeStrategy". See the "NOTES MERGE STRATEGIES" section in
           git-notes(1) for more information on the available strategies.

       notes.displayRef
           The (fully qualified) refname from which to show notes when showing
           commit messages. The value of this variable can be set to a glob,
           in which case notes from all matching refs will be shown. You may
           also specify this configuration variable several times. A warning
           will be issued for refs that do not exist, but a glob that does not
           match any refs is silently ignored.

           This setting can be overridden with the GIT_NOTES_DISPLAY_REF
           environment variable, which must be a colon separated list of refs
           or globs.

           The effective value of "core.notesRef" (possibly overridden by
           GIT_NOTES_REF) is also implicitly added to the list of refs to be
           displayed.

       notes.rewrite.<command>
           When rewriting commits with <command> (currently amend or rebase)
           and this variable is set to true, Git automatically copies your
           notes from the original to the rewritten commit. Defaults to true,
           but see "notes.rewriteRef" below.

       notes.rewriteMode
           When copying notes during a rewrite (see the
           "notes.rewrite.<command>" option), determines what to do if the
           target commit already has a note. Must be one of overwrite,
           concatenate, cat_sort_uniq, or ignore. Defaults to concatenate.

           This setting can be overridden with the GIT_NOTES_REWRITE_MODE
           environment variable.

       notes.rewriteRef
           When copying notes during a rewrite, specifies the (fully
           qualified) ref whose notes should be copied. The ref may be a glob,
           in which case notes in all matching refs will be copied. You may
           also specify this configuration several times.

           Does not have a default value; you must configure this variable to
           enable note rewriting. Set it to refs/notes/commits to enable
           rewriting for the default commit notes.

           This setting can be overridden with the GIT_NOTES_REWRITE_REF
           environment variable, which must be a colon separated list of refs
           or globs.

       pack.window
           The size of the window used by git-pack-objects(1) when no window
           size is given on the command line. Defaults to 10.

       pack.depth
           The maximum delta depth used by git-pack-objects(1) when no maximum
           depth is given on the command line. Defaults to 50. Maximum value
           is 4095.

       pack.windowMemory
           The maximum size of memory that is consumed by each thread in git-
           pack-objects(1) for pack window memory when no limit is given on
           the command line. The value can be suffixed with "k", "m", or "g".
           When left unconfigured (or set explicitly to 0), there will be no
           limit.

       pack.compression
           An integer -1..9, indicating the compression level for objects in a
           pack file. -1 is the zlib default. 0 means no compression, and 1..9
           are various speed/size tradeoffs, 9 being slowest. If not set,
           defaults to core.compression. If that is not set, defaults to -1,
           the zlib default, which is "a default compromise between speed and
           compression (currently equivalent to level 6)."

           Note that changing the compression level will not automatically
           recompress all existing objects. You can force recompression by
           passing the -F option to git-repack(1).

       pack.allowPackReuse
           When true, and when reachability bitmaps are enabled, pack-objects
           will try to send parts of the bitmapped packfile verbatim. This can
           reduce memory and CPU usage to serve fetches, but might result in
           sending a slightly larger pack. Defaults to true.

       pack.island
           An extended regular expression configuring a set of delta islands.
           See "DELTA ISLANDS" in git-pack-objects(1) for details.

       pack.islandCore
           Specify an island name which gets to have its objects be packed
           first. This creates a kind of pseudo-pack at the front of one pack,
           so that the objects from the specified island are hopefully faster
           to copy into any pack that should be served to a user requesting
           these objects. In practice this means that the island specified
           should likely correspond to what is the most commonly cloned in the
           repo. See also "DELTA ISLANDS" in git-pack-objects(1).

       pack.deltaCacheSize
           The maximum memory in bytes used for caching deltas in git-pack-
           objects(1) before writing them out to a pack. This cache is used to
           speed up the writing object phase by not having to recompute the
           final delta result once the best match for all objects is found.
           Repacking large repositories on machines which are tight with
           memory might be badly impacted by this though, especially if this
           cache pushes the system into swapping. A value of 0 means no limit.
           The smallest size of 1 byte may be used to virtually disable this
           cache. Defaults to 256 MiB.

       pack.deltaCacheLimit
           The maximum size of a delta, that is cached in git-pack-objects(1).
           This cache is used to speed up the writing object phase by not
           having to recompute the final delta result once the best match for
           all objects is found. Defaults to 1000. Maximum value is 65535.

       pack.threads
           Specifies the number of threads to spawn when searching for best
           delta matches. This requires that git-pack-objects(1) be compiled
           with pthreads otherwise this option is ignored with a warning. This
           is meant to reduce packing time on multiprocessor machines. The
           required amount of memory for the delta search window is however
           multiplied by the number of threads. Specifying 0 will cause Git to
           auto-detect the number of CPU's and set the number of threads
           accordingly.

       pack.indexVersion
           Specify the default pack index version. Valid values are 1 for
           legacy pack index used by Git versions prior to 1.5.2, and 2 for
           the new pack index with capabilities for packs larger than 4 GB as
           well as proper protection against the repacking of corrupted packs.
           Version 2 is the default. Note that version 2 is enforced and this
           config option ignored whenever the corresponding pack is larger
           than 2 GB.

           If you have an old Git that does not understand the version 2 *.idx
           file, cloning or fetching over a non native protocol (e.g. "http")
           that will copy both *.pack file and corresponding *.idx file from
           the other side may give you a repository that cannot be accessed
           with your older version of Git. If the *.pack file is smaller than
           2 GB, however, you can use git-index-pack(1) on the *.pack file to
           regenerate the *.idx file.

       pack.packSizeLimit
           The maximum size of a pack. This setting only affects packing to a
           file when repacking, i.e. the git:// protocol is unaffected. It can
           be overridden by the --max-pack-size option of git-repack(1).
           Reaching this limit results in the creation of multiple packfiles;
           which in turn prevents bitmaps from being created. The minimum size
           allowed is limited to 1 MiB. The default is unlimited. Common unit
           suffixes of k, m, or g are supported.

       pack.useBitmaps
           When true, git will use pack bitmaps (if available) when packing to
           stdout (e.g., during the server side of a fetch). Defaults to true.
           You should not generally need to turn this off unless you are
           debugging pack bitmaps.

       pack.useSparse
           When true, git will default to using the --sparse option in git
           pack-objects when the --revs option is present. This algorithm only
           walks trees that appear in paths that introduce new objects. This
           can have significant performance benefits when computing a pack to
           send a small change. However, it is possible that extra objects are
           added to the pack-file if the included commits contain certain
           types of direct renames. Default is true.

       pack.writeBitmaps (deprecated)
           This is a deprecated synonym for repack.writeBitmaps.

       pack.writeBitmapHashCache
           When true, git will include a "hash cache" section in the bitmap
           index (if one is written). This cache can be used to feed git's
           delta heuristics, potentially leading to better deltas between
           bitmapped and non-bitmapped objects (e.g., when serving a fetch
           between an older, bitmapped pack and objects that have been pushed
           since the last gc). The downside is that it consumes 4 bytes per
           object of disk space. Defaults to true.

       pager.<cmd>
           If the value is boolean, turns on or off pagination of the output
           of a particular Git subcommand when writing to a tty. Otherwise,
           turns on pagination for the subcommand using the pager specified by
           the value of pager.<cmd>. If --paginate or --no-pager is specified
           on the command line, it takes precedence over this option. To
           disable pagination for all commands, set core.pager or GIT_PAGER to
           cat.

       pretty.<name>
           Alias for a --pretty= format string, as specified in git-log(1).
           Any aliases defined here can be used just as the built-in pretty
           formats could. For example, running git config pretty.changelog
           "format:* %H %s" would cause the invocation git log
           --pretty=changelog to be equivalent to running git log
           "--pretty=format:* %H %s". Note that an alias with the same name as
           a built-in format will be silently ignored.

       protocol.allow
           If set, provide a user defined default policy for all protocols
           which don't explicitly have a policy (protocol.<name>.allow). By
           default, if unset, known-safe protocols (http, https, git, ssh,
           file) have a default policy of always, known-dangerous protocols
           (ext) have a default policy of never, and all other protocols have
           a default policy of user. Supported policies:

           o   always - protocol is always able to be used.

           o   never - protocol is never able to be used.

           o   user - protocol is only able to be used when
               GIT_PROTOCOL_FROM_USER is either unset or has a value of 1.
               This policy should be used when you want a protocol to be
               directly usable by the user but don't want it used by commands
               which execute clone/fetch/push commands without user input,
               e.g. recursive submodule initialization.

       protocol.<name>.allow
           Set a policy to be used by protocol <name> with clone/fetch/push
           commands. See protocol.allow above for the available policies.

           The protocol names currently used by git are:

           o   file: any local file-based path (including file:// URLs, or
               local paths)

           o   git: the anonymous git protocol over a direct TCP connection
               (or proxy, if configured)

           o   ssh: git over ssh (including host:path syntax, ssh://, etc).

           o   http: git over http, both "smart http" and "dumb http". Note
               that this does not include https; if you want to configure
               both, you must do so individually.

           o   any external helpers are named by their protocol (e.g., use hg
               to allow the git-remote-hg helper)

       protocol.version
           If set, clients will attempt to communicate with a server using the
           specified protocol version. If the server does not support it,
           communication falls back to version 0. If unset, the default is 0.
           Supported versions:

           o   0 - the original wire protocol.

           o   1 - the original wire protocol with the addition of a version
               string in the initial response from the server.

           o   2 - wire protocol version 2[2].

       pull.ff
           By default, Git does not create an extra merge commit when merging
           a commit that is a descendant of the current commit. Instead, the
           tip of the current branch is fast-forwarded. When set to false,
           this variable tells Git to create an extra merge commit in such a
           case (equivalent to giving the --no-ff option from the command
           line). When set to only, only such fast-forward merges are allowed
           (equivalent to giving the --ff-only option from the command line).
           This setting overrides merge.ff when pulling.

       pull.rebase
           When true, rebase branches on top of the fetched branch, instead of
           merging the default branch from the default remote when "git pull"
           is run. See "branch.<name>.rebase" for setting this on a per-branch
           basis.

           When merges (or just m), pass the --rebase-merges option to git
           rebase so that the local merge commits are included in the rebase
           (see git-rebase(1) for details).

           When preserve (or just p, deprecated in favor of merges), also pass
           --preserve-merges along to git rebase so that locally committed
           merge commits will not be flattened by running git pull.

           When the value is interactive (or just i), the rebase is run in
           interactive mode.

           NOTE: this is a possibly dangerous operation; do not use it unless
           you understand the implications (see git-rebase(1) for details).

       pull.octopus
           The default merge strategy to use when pulling multiple branches at
           once.

       pull.twohead
           The default merge strategy to use when pulling a single branch.

       push.default
           Defines the action git push should take if no refspec is given
           (whether from the command-line, config, or elsewhere). Different
           values are well-suited for specific workflows; for instance, in a
           purely central workflow (i.e. the fetch source is equal to the push
           destination), upstream is probably what you want. Possible values
           are:

           o   nothing - do not push anything (error out) unless a refspec is
               given. This is primarily meant for people who want to avoid
               mistakes by always being explicit.

           o   current - push the current branch to update a branch with the
               same name on the receiving end. Works in both central and
               non-central workflows.

           o   upstream - push the current branch back to the branch whose
               changes are usually integrated into the current branch (which
               is called @{upstream}). This mode only makes sense if you are
               pushing to the same repository you would normally pull from
               (i.e. central workflow).

           o   tracking - This is a deprecated synonym for upstream.

           o   simple - in centralized workflow, work like upstream with an
               added safety to refuse to push if the upstream branch's name is
               different from the local one.

               When pushing to a remote that is different from the remote you
               normally pull from, work as current. This is the safest option
               and is suited for beginners.

               This mode has become the default in Git 2.0.

           o   matching - push all branches having the same name on both ends.
               This makes the repository you are pushing to remember the set
               of branches that will be pushed out (e.g. if you always push
               maint and master there and no other branches, the repository
               you push to will have these two branches, and your local maint
               and master will be pushed there).

               To use this mode effectively, you have to make sure all the
               branches you would push out are ready to be pushed out before
               running git push, as the whole point of this mode is to allow
               you to push all of the branches in one go. If you usually
               finish work on only one branch and push out the result, while
               other branches are unfinished, this mode is not for you. Also
               this mode is not suitable for pushing into a shared central
               repository, as other people may add new branches there, or
               update the tip of existing branches outside your control.

               This used to be the default, but not since Git 2.0 (simple is
               the new default).

       push.followTags
           If set to true enable --follow-tags option by default. You may
           override this configuration at time of push by specifying
           --no-follow-tags.

       push.gpgSign
           May be set to a boolean value, or the string if-asked. A true value
           causes all pushes to be GPG signed, as if --signed is passed to
           git-push(1). The string if-asked causes pushes to be signed if the
           server supports it, as if --signed=if-asked is passed to git push.
           A false value may override a value from a lower-priority config
           file. An explicit command-line flag always overrides this config
           option.

       push.pushOption
           When no --push-option=<option> argument is given from the command
           line, git push behaves as if each <value> of this variable is given
           as --push-option=<value>.

           This is a multi-valued variable, and an empty value can be used in
           a higher priority configuration file (e.g.  .git/config in a
           repository) to clear the values inherited from a lower priority
           configuration files (e.g.  $HOME/.gitconfig).

               Example:

               /etc/gitconfig
                 push.pushoption = a
                 push.pushoption = b

               ~/.gitconfig
                 push.pushoption = c

               repo/.git/config
                 push.pushoption =
                 push.pushoption = b

               This will result in only b (a and c are cleared).

       push.recurseSubmodules
           Make sure all submodule commits used by the revisions to be pushed
           are available on a remote-tracking branch. If the value is check
           then Git will verify that all submodule commits that changed in the
           revisions to be pushed are available on at least one remote of the
           submodule. If any commits are missing, the push will be aborted and
           exit with non-zero status. If the value is on-demand then all
           submodules that changed in the revisions to be pushed will be
           pushed. If on-demand was not able to push all necessary revisions
           it will also be aborted and exit with non-zero status. If the value
           is no then default behavior of ignoring submodules when pushing is
           retained. You may override this configuration at time of push by
           specifying --recurse-submodules=check|on-demand|no. If not set, no
           is used by default, unless submodule.recurse is set (in which case
           a true value means on-demand).

       rebase.useBuiltin
           Unused configuration variable. Used in Git versions 2.20 and 2.21
           as an escape hatch to enable the legacy shellscript implementation
           of rebase. Now the built-in rewrite of it in C is always used.
           Setting this will emit a warning, to alert any remaining users that
           setting this now does nothing.

       rebase.backend
           Default backend to use for rebasing. Possible choices are apply or
           merge. In the future, if the merge backend gains all remaining
           capabilities of the apply backend, this setting may become unused.

       rebase.stat
           Whether to show a diffstat of what changed upstream since the last
           rebase. False by default.

       rebase.autoSquash
           If set to true enable --autosquash option by default.

       rebase.autoStash
           When set to true, automatically create a temporary stash entry
           before the operation begins, and apply it after the operation ends.
           This means that you can run rebase on a dirty worktree. However,
           use with care: the final stash application after a successful
           rebase might result in non-trivial conflicts. This option can be
           overridden by the --no-autostash and --autostash options of git-
           rebase(1). Defaults to false.

       rebase.missingCommitsCheck
           If set to "warn", git rebase -i will print a warning if some
           commits are removed (e.g. a line was deleted), however the rebase
           will still proceed. If set to "error", it will print the previous
           warning and stop the rebase, git rebase --edit-todo can then be
           used to correct the error. If set to "ignore", no checking is done.
           To drop a commit without warning or error, use the drop command in
           the todo list. Defaults to "ignore".

       rebase.instructionFormat
           A format string, as specified in git-log(1), to be used for the
           todo list during an interactive rebase. The format will
           automatically have the long commit hash prepended to the format.

       rebase.abbreviateCommands
           If set to true, git rebase will use abbreviated command names in
           the todo list resulting in something like this:

                       p deadbee The oneline of the commit
                       p fa1afe1 The oneline of the next commit
                       ...

           instead of:

                       pick deadbee The oneline of the commit
                       pick fa1afe1 The oneline of the next commit
                       ...

           Defaults to false.

       rebase.rescheduleFailedExec
           Automatically reschedule exec commands that failed. This only makes
           sense in interactive mode (or when an --exec option was provided).
           This is the same as specifying the --reschedule-failed-exec option.

       receive.advertiseAtomic
           By default, git-receive-pack will advertise the atomic push
           capability to its clients. If you don't want to advertise this
           capability, set this variable to false.

       receive.advertisePushOptions
           When set to true, git-receive-pack will advertise the push options
           capability to its clients. False by default.

       receive.autogc
           By default, git-receive-pack will run "git-gc --auto" after
           receiving data from git-push and updating refs. You can stop it by
           setting this variable to false.

       receive.certNonceSeed
           By setting this variable to a string, git receive-pack will accept
           a git push --signed and verifies it by using a "nonce" protected by
           HMAC using this string as a secret key.

       receive.certNonceSlop
           When a git push --signed sent a push certificate with a "nonce"
           that was issued by a receive-pack serving the same repository
           within this many seconds, export the "nonce" found in the
           certificate to GIT_PUSH_CERT_NONCE to the hooks (instead of what
           the receive-pack asked the sending side to include). This may allow
           writing checks in pre-receive and post-receive a bit easier.
           Instead of checking GIT_PUSH_CERT_NONCE_SLOP environment variable
           that records by how many seconds the nonce is stale to decide if
           they want to accept the certificate, they only can check
           GIT_PUSH_CERT_NONCE_STATUS is OK.

       receive.fsckObjects
           If it is set to true, git-receive-pack will check all received
           objects. See transfer.fsckObjects for what's checked. Defaults to
           false. If not set, the value of transfer.fsckObjects is used
           instead.

       receive.fsck.<msg-id>
           Acts like fsck.<msg-id>, but is used by git-receive-pack(1) instead
           of git-fsck(1). See the fsck.<msg-id> documentation for details.

       receive.fsck.skipList
           Acts like fsck.skipList, but is used by git-receive-pack(1) instead
           of git-fsck(1). See the fsck.skipList documentation for details.

       receive.keepAlive
           After receiving the pack from the client, receive-pack may produce
           no output (if --quiet was specified) while processing the pack,
           causing some networks to drop the TCP connection. With this option
           set, if receive-pack does not transmit any data in this phase for
           receive.keepAlive seconds, it will send a short keepalive packet.
           The default is 5 seconds; set to 0 to disable keepalives entirely.

       receive.unpackLimit
           If the number of objects received in a push is below this limit
           then the objects will be unpacked into loose object files. However
           if the number of received objects equals or exceeds this limit then
           the received pack will be stored as a pack, after adding any
           missing delta bases. Storing the pack from a push can make the push
           operation complete faster, especially on slow filesystems. If not
           set, the value of transfer.unpackLimit is used instead.

       receive.maxInputSize
           If the size of the incoming pack stream is larger than this limit,
           then git-receive-pack will error out, instead of accepting the pack
           file. If not set or set to 0, then the size is unlimited.

       receive.denyDeletes
           If set to true, git-receive-pack will deny a ref update that
           deletes the ref. Use this to prevent such a ref deletion via a
           push.

       receive.denyDeleteCurrent
           If set to true, git-receive-pack will deny a ref update that
           deletes the currently checked out branch of a non-bare repository.

       receive.denyCurrentBranch
           If set to true or "refuse", git-receive-pack will deny a ref update
           to the currently checked out branch of a non-bare repository. Such
           a push is potentially dangerous because it brings the HEAD out of
           sync with the index and working tree. If set to "warn", print a
           warning of such a push to stderr, but allow the push to proceed. If
           set to false or "ignore", allow such pushes with no message.
           Defaults to "refuse".

           Another option is "updateInstead" which will update the working
           tree if pushing into the current branch. This option is intended
           for synchronizing working directories when one side is not easily
           accessible via interactive ssh (e.g. a live web site, hence the
           requirement that the working directory be clean). This mode also
           comes in handy when developing inside a VM to test and fix code on
           different Operating Systems.

           By default, "updateInstead" will refuse the push if the working
           tree or the index have any difference from the HEAD, but the
           push-to-checkout hook can be used to customize this. See
           githooks(5).

       receive.denyNonFastForwards
           If set to true, git-receive-pack will deny a ref update which is
           not a fast-forward. Use this to prevent such an update via a push,
           even if that push is forced. This configuration variable is set
           when initializing a shared repository.

       receive.hideRefs
           This variable is the same as transfer.hideRefs, but applies only to
           receive-pack (and so affects pushes, but not fetches). An attempt
           to update or delete a hidden ref by git push is rejected.

       receive.updateServerInfo
           If set to true, git-receive-pack will run git-update-server-info
           after receiving data from git-push and updating refs.

       receive.shallowUpdate
           If set to true, .git/shallow can be updated when new refs require
           new shallow roots. Otherwise those refs are rejected.

       remote.pushDefault
           The remote to push to by default. Overrides branch.<name>.remote
           for all branches, and is overridden by branch.<name>.pushRemote for
           specific branches.

       remote.<name>.url
           The URL of a remote repository. See git-fetch(1) or git-push(1).

       remote.<name>.pushurl
           The push URL of a remote repository. See git-push(1).

       remote.<name>.proxy
           For remotes that require curl (http, https and ftp), the URL to the
           proxy to use for that remote. Set to the empty string to disable
           proxying for that remote.

       remote.<name>.proxyAuthMethod
           For remotes that require curl (http, https and ftp), the method to
           use for authenticating against the proxy in use (probably set in
           remote.<name>.proxy). See http.proxyAuthMethod.

       remote.<name>.fetch
           The default set of "refspec" for git-fetch(1). See git-fetch(1).

       remote.<name>.push
           The default set of "refspec" for git-push(1). See git-push(1).

       remote.<name>.mirror
           If true, pushing to this remote will automatically behave as if the
           --mirror option was given on the command line.

       remote.<name>.skipDefaultUpdate
           If true, this remote will be skipped by default when updating using
           git-fetch(1) or the update subcommand of git-remote(1).

       remote.<name>.skipFetchAll
           If true, this remote will be skipped by default when updating using
           git-fetch(1) or the update subcommand of git-remote(1).

       remote.<name>.receivepack
           The default program to execute on the remote side when pushing. See
           option --receive-pack of git-push(1).

       remote.<name>.uploadpack
           The default program to execute on the remote side when fetching.
           See option --upload-pack of git-fetch-pack(1).

       remote.<name>.tagOpt
           Setting this value to --no-tags disables automatic tag following
           when fetching from remote <name>. Setting it to --tags will fetch
           every tag from remote <name>, even if they are not reachable from
           remote branch heads. Passing these flags directly to git-fetch(1)
           can override this setting. See options --tags and --no-tags of git-
           fetch(1).

       remote.<name>.vcs
           Setting this to a value <vcs> will cause Git to interact with the
           remote with the git-remote-<vcs> helper.

       remote.<name>.prune
           When set to true, fetching from this remote by default will also
           remove any remote-tracking references that no longer exist on the
           remote (as if the --prune option was given on the command line).
           Overrides fetch.prune settings, if any.

       remote.<name>.pruneTags
           When set to true, fetching from this remote by default will also
           remove any local tags that no longer exist on the remote if pruning
           is activated in general via remote.<name>.prune, fetch.prune or
           --prune. Overrides fetch.pruneTags settings, if any.

           See also remote.<name>.prune and the PRUNING section of git-
           fetch(1).

       remote.<name>.promisor
           When set to true, this remote will be used to fetch promisor
           objects.

       remote.<name>.partialclonefilter
           The filter that will be applied when fetching from this promisor
           remote.

       remotes.<group>
           The list of remotes which are fetched by "git remote update
           <group>". See git-remote(1).

       repack.useDeltaBaseOffset
           By default, git-repack(1) creates packs that use delta-base offset.
           If you need to share your repository with Git older than version
           1.4.4, either directly or via a dumb protocol such as http, then
           you need to set this option to "false" and repack. Access from old
           Git versions over the native protocol are unaffected by this
           option.

       repack.packKeptObjects
           If set to true, makes git repack act as if --pack-kept-objects was
           passed. See git-repack(1) for details. Defaults to false normally,
           but true if a bitmap index is being written (either via
           --write-bitmap-index or repack.writeBitmaps).

       repack.useDeltaIslands
           If set to true, makes git repack act as if --delta-islands was
           passed. Defaults to false.

       repack.writeBitmaps
           When true, git will write a bitmap index when packing all objects
           to disk (e.g., when git repack -a is run). This index can speed up
           the "counting objects" phase of subsequent packs created for clones
           and fetches, at the cost of some disk space and extra time spent on
           the initial repack. This has no effect if multiple packfiles are
           created. Defaults to true on bare repos, false otherwise.

       rerere.autoUpdate
           When set to true, git-rerere updates the index with the resulting
           contents after it cleanly resolves conflicts using previously
           recorded resolution. Defaults to false.

       rerere.enabled
           Activate recording of resolved conflicts, so that identical
           conflict hunks can be resolved automatically, should they be
           encountered again. By default, git-rerere(1) is enabled if there is
           an rr-cache directory under the $GIT_DIR, e.g. if "rerere" was
           previously used in the repository.

       reset.quiet
           When set to true, git reset will default to the --quiet option.

       sendemail.identity
           A configuration identity. When given, causes values in the
           sendemail.<identity> subsection to take precedence over values in
           the sendemail section. The default identity is the value of
           sendemail.identity.

       sendemail.smtpEncryption
           See git-send-email(1) for description. Note that this setting is
           not subject to the identity mechanism.

       sendemail.smtpssl (deprecated)
           Deprecated alias for sendemail.smtpEncryption = ssl.

       sendemail.smtpsslcertpath
           Path to ca-certificates (either a directory or a single file). Set
           it to an empty string to disable certificate verification.

       sendemail.<identity>.*
           Identity-specific versions of the sendemail.*  parameters found
           below, taking precedence over those when this identity is selected,
           through either the command-line or sendemail.identity.

       sendemail.aliasesFile, sendemail.aliasFileType, sendemail.annotate,
       sendemail.bcc, sendemail.cc, sendemail.ccCmd, sendemail.chainReplyTo,
       sendemail.confirm, sendemail.envelopeSender, sendemail.from,
       sendemail.multiEdit, sendemail.signedoffbycc, sendemail.smtpPass,
       sendemail.suppresscc, sendemail.suppressFrom, sendemail.to,
       sendemail.tocmd, sendemail.smtpDomain, sendemail.smtpServer,
       sendemail.smtpServerPort, sendemail.smtpServerOption,
       sendemail.smtpUser, sendemail.thread, sendemail.transferEncoding,
       sendemail.validate, sendemail.xmailer
           See git-send-email(1) for description.

       sendemail.signedoffcc (deprecated)
           Deprecated alias for sendemail.signedoffbycc.

       sendemail.smtpBatchSize
           Number of messages to be sent per connection, after that a relogin
           will happen. If the value is 0 or undefined, send all messages in
           one connection. See also the --batch-size option of git-send-
           email(1).

       sendemail.smtpReloginDelay
           Seconds wait before reconnecting to smtp server. See also the
           --relogin-delay option of git-send-email(1).

       sequence.editor
           Text editor used by git rebase -i for editing the rebase
           instruction file. The value is meant to be interpreted by the shell
           when it is used. It can be overridden by the GIT_SEQUENCE_EDITOR
           environment variable. When not configured the default commit
           message editor is used instead.

       showBranch.default
           The default set of branches for git-show-branch(1). See git-show-
           branch(1).

       splitIndex.maxPercentChange
           When the split index feature is used, this specifies the percent of
           entries the split index can contain compared to the total number of
           entries in both the split index and the shared index before a new
           shared index is written. The value should be between 0 and 100. If
           the value is 0 then a new shared index is always written, if it is
           100 a new shared index is never written. By default the value is
           20, so a new shared index is written if the number of entries in
           the split index would be greater than 20 percent of the total
           number of entries. See git-update-index(1).

       splitIndex.sharedIndexExpire
           When the split index feature is used, shared index files that were
           not modified since the time this variable specifies will be removed
           when a new shared index file is created. The value "now" expires
           all entries immediately, and "never" suppresses expiration
           altogether. The default value is "2.weeks.ago". Note that a shared
           index file is considered modified (for the purpose of expiration)
           each time a new split-index file is either created based on it or
           read from it. See git-update-index(1).

       ssh.variant
           By default, Git determines the command line arguments to use based
           on the basename of the configured SSH command (configured using the
           environment variable GIT_SSH or GIT_SSH_COMMAND or the config
           setting core.sshCommand). If the basename is unrecognized, Git will
           attempt to detect support of OpenSSH options by first invoking the
           configured SSH command with the -G (print configuration) option and
           will subsequently use OpenSSH options (if that is successful) or no
           options besides the host and remote command (if it fails).

           The config variable ssh.variant can be set to override this
           detection. Valid values are ssh (to use OpenSSH options), plink,
           putty, tortoiseplink, simple (no options except the host and remote
           command). The default auto-detection can be explicitly requested
           using the value auto. Any other value is treated as ssh. This
           setting can also be overridden via the environment variable
           GIT_SSH_VARIANT.

           The current command-line parameters used for each variant are as
           follows:

           o   ssh - [-p port] [-4] [-6] [-o option] [username@]host command

           o   simple - [username@]host command

           o   plink or putty - [-P port] [-4] [-6] [username@]host command

           o   tortoiseplink - [-P port] [-4] [-6] -batch [username@]host
               command

           Except for the simple variant, command-line parameters are likely
           to change as git gains new features.

       status.relativePaths
           By default, git-status(1) shows paths relative to the current
           directory. Setting this variable to false shows paths relative to
           the repository root (this was the default for Git prior to v1.5.4).

       status.short
           Set to true to enable --short by default in git-status(1). The
           option --no-short takes precedence over this variable.

       status.branch
           Set to true to enable --branch by default in git-status(1). The
           option --no-branch takes precedence over this variable.

       status.aheadBehind
           Set to true to enable --ahead-behind and false to enable
           --no-ahead-behind by default in git-status(1) for non-porcelain
           status formats. Defaults to true.

       status.displayCommentPrefix
           If set to true, git-status(1) will insert a comment prefix before
           each output line (starting with core.commentChar, i.e.  # by
           default). This was the behavior of git-status(1) in Git 1.8.4 and
           previous. Defaults to false.

       status.renameLimit
           The number of files to consider when performing rename detection in
           git-status(1) and git-commit(1). Defaults to the value of
           diff.renameLimit.

       status.renames
           Whether and how Git detects renames in git-status(1) and git-
           commit(1) . If set to "false", rename detection is disabled. If set
           to "true", basic rename detection is enabled. If set to "copies" or
           "copy", Git will detect copies, as well. Defaults to the value of
           diff.renames.

       status.showStash
           If set to true, git-status(1) will display the number of entries
           currently stashed away. Defaults to false.

       status.showUntrackedFiles
           By default, git-status(1) and git-commit(1) show files which are
           not currently tracked by Git. Directories which contain only
           untracked files, are shown with the directory name only. Showing
           untracked files means that Git needs to lstat() all the files in
           the whole repository, which might be slow on some systems. So, this
           variable controls how the commands displays the untracked files.
           Possible values are:

           o   no - Show no untracked files.

           o   normal - Show untracked files and directories.

           o   all - Show also individual files in untracked directories.

           If this variable is not specified, it defaults to normal. This
           variable can be overridden with the -u|--untracked-files option of
           git-status(1) and git-commit(1).

       status.submoduleSummary
           Defaults to false. If this is set to a non zero number or true
           (identical to -1 or an unlimited number), the submodule summary
           will be enabled and a summary of commits for modified submodules
           will be shown (see --summary-limit option of git-submodule(1)).
           Please note that the summary output command will be suppressed for
           all submodules when diff.ignoreSubmodules is set to all or only for
           those submodules where submodule.<name>.ignore=all. The only
           exception to that rule is that status and commit will show staged
           submodule changes. To also view the summary for ignored submodules
           you can either use the --ignore-submodules=dirty command-line
           option or the git submodule summary command, which shows a similar
           output but does not honor these settings.

       stash.useBuiltin
           Unused configuration variable. Used in Git versions 2.22 to 2.26 as
           an escape hatch to enable the legacy shellscript implementation of
           stash. Now the built-in rewrite of it in C is always used. Setting
           this will emit a warning, to alert any remaining users that setting
           this now does nothing.

       stash.showPatch
           If this is set to true, the git stash show command without an
           option will show the stash entry in patch form. Defaults to false.
           See description of show command in git-stash(1).

       stash.showStat
           If this is set to true, the git stash show command without an
           option will show diffstat of the stash entry. Defaults to true. See
           description of show command in git-stash(1).

       submodule.<name>.url
           The URL for a submodule. This variable is copied from the
           .gitmodules file to the git config via git submodule init. The user
           can change the configured URL before obtaining the submodule via
           git submodule update. If neither submodule.<name>.active or
           submodule.active are set, the presence of this variable is used as
           a fallback to indicate whether the submodule is of interest to git
           commands. See git-submodule(1) and gitmodules(5) for details.

       submodule.<name>.update
           The method by which a submodule is updated by git submodule update,
           which is the only affected command, others such as git checkout
           --recurse-submodules are unaffected. It exists for historical
           reasons, when git submodule was the only command to interact with
           submodules; settings like submodule.active and pull.rebase are more
           specific. It is populated by git submodule init from the
           gitmodules(5) file. See description of update command in git-
           submodule(1).

       submodule.<name>.branch
           The remote branch name for a submodule, used by git submodule
           update --remote. Set this option to override the value found in the
           .gitmodules file. See git-submodule(1) and gitmodules(5) for
           details.

       submodule.<name>.fetchRecurseSubmodules
           This option can be used to control recursive fetching of this
           submodule. It can be overridden by using the
           --[no-]recurse-submodules command-line option to "git fetch" and
           "git pull". This setting will override that from in the
           gitmodules(5) file.

       submodule.<name>.ignore
           Defines under what circumstances "git status" and the diff family
           show a submodule as modified. When set to "all", it will never be
           considered modified (but it will nonetheless show up in the output
           of status and commit when it has been staged), "dirty" will ignore
           all changes to the submodules work tree and takes only differences
           between the HEAD of the submodule and the commit recorded in the
           superproject into account. "untracked" will additionally let
           submodules with modified tracked files in their work tree show up.
           Using "none" (the default when this option is not set) also shows
           submodules that have untracked files in their work tree as changed.
           This setting overrides any setting made in .gitmodules for this
           submodule, both settings can be overridden on the command line by
           using the "--ignore-submodules" option. The git submodule commands
           are not affected by this setting.

       submodule.<name>.active
           Boolean value indicating if the submodule is of interest to git
           commands. This config option takes precedence over the
           submodule.active config option. See gitsubmodules(7) for details.

       submodule.active
           A repeated field which contains a pathspec used to match against a
           submodule's path to determine if the submodule is of interest to
           git commands. See gitsubmodules(7) for details.

       submodule.recurse
           Specifies if commands recurse into submodules by default. This
           applies to all commands that have a --recurse-submodules option
           (checkout, fetch, grep, pull, push, read-tree, reset, restore and
           switch) except clone and ls-files. Defaults to false. When set to
           true, it can be deactivated via the --no-recurse-submodules option.
           Note that some Git commands lacking this option may call some of
           the above commands affected by submodule.recurse; for instance git
           remote update will call git fetch but does not have a
           --no-recurse-submodules option. For these commands a workaround is
           to temporarily change the configuration value by using git -c
           submodule.recurse=0.

       submodule.fetchJobs
           Specifies how many submodules are fetched/cloned at the same time.
           A positive integer allows up to that number of submodules fetched
           in parallel. A value of 0 will give some reasonable default. If
           unset, it defaults to 1.

       submodule.alternateLocation
           Specifies how the submodules obtain alternates when submodules are
           cloned. Possible values are no, superproject. By default no is
           assumed, which doesn't add references. When the value is set to
           superproject the submodule to be cloned computes its alternates
           location relative to the superprojects alternate.

       submodule.alternateErrorStrategy
           Specifies how to treat errors with the alternates for a submodule
           as computed via submodule.alternateLocation. Possible values are
           ignore, info, die. Default is die. Note that if set to ignore or
           info, and if there is an error with the computed alternate, the
           clone proceeds as if no alternate was specified.

       tag.forceSignAnnotated
           A boolean to specify whether annotated tags created should be GPG
           signed. If --annotate is specified on the command line, it takes
           precedence over this option.

       tag.sort
           This variable controls the sort ordering of tags when displayed by
           git-tag(1). Without the "--sort=<value>" option provided, the value
           of this variable will be used as the default.

       tag.gpgSign
           A boolean to specify whether all tags should be GPG signed. Use of
           this option when running in an automated script can result in a
           large number of tags being signed. It is therefore convenient to
           use an agent to avoid typing your gpg passphrase several times.
           Note that this option doesn't affect tag signing behavior enabled
           by "-u <keyid>" or "--local-user=<keyid>" options.

       tar.umask
           This variable can be used to restrict the permission bits of tar
           archive entries. The default is 0002, which turns off the world
           write bit. The special value "user" indicates that the archiving
           user's umask will be used instead. See umask(2) and git-archive(1).

       Trace2 config settings are only read from the system and global config
       files; repository local and worktree config files and -c command line
       arguments are not respected.

       trace2.normalTarget
           This variable controls the normal target destination. It may be
           overridden by the GIT_TRACE2 environment variable. The following
           table shows possible values.

       trace2.perfTarget
           This variable controls the performance target destination. It may
           be overridden by the GIT_TRACE2_PERF environment variable. The
           following table shows possible values.

       trace2.eventTarget
           This variable controls the event target destination. It may be
           overridden by the GIT_TRACE2_EVENT environment variable. The
           following table shows possible values.

           o   0 or false - Disables the target.

           o   1 or true - Writes to STDERR.

           o   [2-9] - Writes to the already opened file descriptor.

           o   <absolute-pathname> - Writes to the file in append mode. If the
               target already exists and is a directory, the traces will be
               written to files (one per process) underneath the given
               directory.

           o   af_unix:[<socket_type>:]<absolute-pathname> - Write to a Unix
               DomainSocket (on platforms that support them). Socket type can
               be either stream or dgram; if omitted Git will try both.

       trace2.normalBrief
           Boolean. When true time, filename, and line fields are omitted from
           normal output. May be overridden by the GIT_TRACE2_BRIEF
           environment variable. Defaults to false.

       trace2.perfBrief
           Boolean. When true time, filename, and line fields are omitted from
           PERF output. May be overridden by the GIT_TRACE2_PERF_BRIEF
           environment variable. Defaults to false.

       trace2.eventBrief
           Boolean. When true time, filename, and line fields are omitted from
           event output. May be overridden by the GIT_TRACE2_EVENT_BRIEF
           environment variable. Defaults to false.

       trace2.eventNesting
           Integer. Specifies desired depth of nested regions in the event
           output. Regions deeper than this value will be omitted. May be
           overridden by the GIT_TRACE2_EVENT_NESTING environment variable.
           Defaults to 2.

       trace2.configParams
           A comma-separated list of patterns of "important" config settings
           that should be recorded in the trace2 output. For example,
           core.*,remote.*.url would cause the trace2 output to contain events
           listing each configured remote. May be overridden by the
           GIT_TRACE2_CONFIG_PARAMS environment variable. Unset by default.

       trace2.envVars
           A comma-separated list of "important" environment variables that
           should be recorded in the trace2 output. For example,
           GIT_HTTP_USER_AGENT,GIT_CONFIG would cause the trace2 output to
           contain events listing the overrides for HTTP user agent and the
           location of the Git configuration file (assuming any are set). May
           be overriden by the GIT_TRACE2_ENV_VARS environment variable. Unset
           by default.

       trace2.destinationDebug
           Boolean. When true Git will print error messages when a trace
           target destination cannot be opened for writing. By default, these
           errors are suppressed and tracing is silently disabled. May be
           overridden by the GIT_TRACE2_DST_DEBUG environment variable.

       trace2.maxFiles
           Integer. When writing trace files to a target directory, do not
           write additional traces if we would exceed this many files.
           Instead, write a sentinel file that will block further tracing to
           this directory. Defaults to 0, which disables this check.

       transfer.fsckObjects
           When fetch.fsckObjects or receive.fsckObjects are not set, the
           value of this variable is used instead. Defaults to false.

           When set, the fetch or receive will abort in the case of a
           malformed object or a link to a nonexistent object. In addition,
           various other issues are checked for, including legacy issues (see
           fsck.<msg-id>), and potential security issues like the existence of
           a .GIT directory or a malicious .gitmodules file (see the release
           notes for v2.2.1 and v2.17.1 for details). Other sanity and
           security checks may be added in future releases.

           On the receiving side, failing fsckObjects will make those objects
           unreachable, see "QUARANTINE ENVIRONMENT" in git-receive-pack(1).
           On the fetch side, malformed objects will instead be left
           unreferenced in the repository.

           Due to the non-quarantine nature of the fetch.fsckObjects
           implementation it cannot be relied upon to leave the object store
           clean like receive.fsckObjects can.

           As objects are unpacked they're written to the object store, so
           there can be cases where malicious objects get introduced even
           though the "fetch" failed, only to have a subsequent "fetch"
           succeed because only new incoming objects are checked, not those
           that have already been written to the object store. That difference
           in behavior should not be relied upon. In the future, such objects
           may be quarantined for "fetch" as well.

           For now, the paranoid need to find some way to emulate the
           quarantine environment if they'd like the same protection as
           "push". E.g. in the case of an internal mirror do the mirroring in
           two steps, one to fetch the untrusted objects, and then do a second
           "push" (which will use the quarantine) to another internal repo,
           and have internal clients consume this pushed-to repository, or
           embargo internal fetches and only allow them once a full "fsck" has
           run (and no new fetches have happened in the meantime).

       transfer.hideRefs
           String(s) receive-pack and upload-pack use to decide which refs to
           omit from their initial advertisements. Use more than one
           definition to specify multiple prefix strings. A ref that is under
           the hierarchies listed in the value of this variable is excluded,
           and is hidden when responding to git push or git fetch. See
           receive.hideRefs and uploadpack.hideRefs for program-specific
           versions of this config.

           You may also include a !  in front of the ref name to negate the
           entry, explicitly exposing it, even if an earlier entry marked it
           as hidden. If you have multiple hideRefs values, later entries
           override earlier ones (and entries in more-specific config files
           override less-specific ones).

           If a namespace is in use, the namespace prefix is stripped from
           each reference before it is matched against transfer.hiderefs
           patterns. For example, if refs/heads/master is specified in
           transfer.hideRefs and the current namespace is foo, then
           refs/namespaces/foo/refs/heads/master is omitted from the
           advertisements but refs/heads/master and
           refs/namespaces/bar/refs/heads/master are still advertised as
           so-called "have" lines. In order to match refs before stripping,
           add a ^ in front of the ref name. If you combine !  and ^, !  must
           be specified first.

           Even if you hide refs, a client may still be able to steal the
           target objects via the techniques described in the "SECURITY"
           section of the gitnamespaces(7) man page; it's best to keep private
           data in a separate repository.

       transfer.unpackLimit
           When fetch.unpackLimit or receive.unpackLimit are not set, the
           value of this variable is used instead. The default value is 100.

       uploadarchive.allowUnreachable
           If true, allow clients to use git archive --remote to request any
           tree, whether reachable from the ref tips or not. See the
           discussion in the "SECURITY" section of git-upload-archive(1) for
           more details. Defaults to false.

       uploadpack.hideRefs
           This variable is the same as transfer.hideRefs, but applies only to
           upload-pack (and so affects only fetches, not pushes). An attempt
           to fetch a hidden ref by git fetch will fail. See also
           uploadpack.allowTipSHA1InWant.

       uploadpack.allowTipSHA1InWant
           When uploadpack.hideRefs is in effect, allow upload-pack to accept
           a fetch request that asks for an object at the tip of a hidden ref
           (by default, such a request is rejected). See also
           uploadpack.hideRefs. Even if this is false, a client may be able to
           steal objects via the techniques described in the "SECURITY"
           section of the gitnamespaces(7) man page; it's best to keep private
           data in a separate repository.

       uploadpack.allowReachableSHA1InWant
           Allow upload-pack to accept a fetch request that asks for an object
           that is reachable from any ref tip. However, note that calculating
           object reachability is computationally expensive. Defaults to
           false. Even if this is false, a client may be able to steal objects
           via the techniques described in the "SECURITY" section of the
           gitnamespaces(7) man page; it's best to keep private data in a
           separate repository.

       uploadpack.allowAnySHA1InWant
           Allow upload-pack to accept a fetch request that asks for any
           object at all. Defaults to false.

       uploadpack.keepAlive
           When upload-pack has started pack-objects, there may be a quiet
           period while pack-objects prepares the pack. Normally it would
           output progress information, but if --quiet was used for the fetch,
           pack-objects will output nothing at all until the pack data begins.
           Some clients and networks may consider the server to be hung and
           give up. Setting this option instructs upload-pack to send an empty
           keepalive packet every uploadpack.keepAlive seconds. Setting this
           option to 0 disables keepalive packets entirely. The default is 5
           seconds.

       uploadpack.packObjectsHook
           If this option is set, when upload-pack would run git pack-objects
           to create a packfile for a client, it will run this shell command
           instead. The pack-objects command and arguments it would have run
           (including the git pack-objects at the beginning) are appended to
           the shell command. The stdin and stdout of the hook are treated as
           if pack-objects itself was run. I.e., upload-pack will feed input
           intended for pack-objects to the hook, and expects a completed
           packfile on stdout.

           Note that this configuration variable is ignored if it is seen in
           the repository-level config (this is a safety measure against
           fetching from untrusted repositories).

       uploadpack.allowFilter
           If this option is set, upload-pack will support partial clone and
           partial fetch object filtering.

       uploadpack.allowRefInWant
           If this option is set, upload-pack will support the ref-in-want
           feature of the protocol version 2 fetch command. This feature is
           intended for the benefit of load-balanced servers which may not
           have the same view of what OIDs their refs point to due to
           replication delay.

       url.<base>.insteadOf
           Any URL that starts with this value will be rewritten to start,
           instead, with <base>. In cases where some site serves a large
           number of repositories, and serves them with multiple access
           methods, and some users need to use different access methods, this
           feature allows people to specify any of the equivalent URLs and
           have Git automatically rewrite the URL to the best alternative for
           the particular user, even for a never-before-seen repository on the
           site. When more than one insteadOf strings match a given URL, the
           longest match is used.

           Note that any protocol restrictions will be applied to the
           rewritten URL. If the rewrite changes the URL to use a custom
           protocol or remote helper, you may need to adjust the
           protocol.*.allow config to permit the request. In particular,
           protocols you expect to use for submodules must be set to always
           rather than the default of user. See the description of
           protocol.allow above.

       url.<base>.pushInsteadOf
           Any URL that starts with this value will not be pushed to; instead,
           it will be rewritten to start with <base>, and the resulting URL
           will be pushed to. In cases where some site serves a large number
           of repositories, and serves them with multiple access methods, some
           of which do not allow push, this feature allows people to specify a
           pull-only URL and have Git automatically use an appropriate URL to
           push, even for a never-before-seen repository on the site. When
           more than one pushInsteadOf strings match a given URL, the longest
           match is used. If a remote has an explicit pushurl, Git will ignore
           this setting for that remote.

       user.name, user.email, author.name, author.email, committer.name,
       committer.email
           The user.name and user.email variables determine what ends up in
           the author and committer field of commit objects. If you need the
           author or committer to be different, the author.name, author.email,
           committer.name or committer.email variables can be set. Also, all
           of these can be overridden by the GIT_AUTHOR_NAME,
           GIT_AUTHOR_EMAIL, GIT_COMMITTER_NAME, GIT_COMMITTER_EMAIL and EMAIL
           environment variables.

           Note that the name forms of these variables conventionally refer to
           some form of a personal name. See git-commit(1) and the environment
           variables section of git(1) for more information on these settings
           and the credential.username option if you're looking for
           authentication credentials instead.

       user.useConfigOnly
           Instruct Git to avoid trying to guess defaults for user.email and
           user.name, and instead retrieve the values only from the
           configuration. For example, if you have multiple email addresses
           and would like to use a different one for each repository, then
           with this configuration option set to true in the global config
           along with a name, Git will prompt you to set up an email before
           making new commits in a newly cloned repository. Defaults to false.

       user.signingKey
           If git-tag(1) or git-commit(1) is not selecting the key you want it
           to automatically when creating a signed tag or commit, you can
           override the default selection with this variable. This option is
           passed unchanged to gpg's --local-user parameter, so you may
           specify a key using any method that gpg supports.

       versionsort.prereleaseSuffix (deprecated)
           Deprecated alias for versionsort.suffix. Ignored if
           versionsort.suffix is set.

       versionsort.suffix
           Even when version sort is used in git-tag(1), tagnames with the
           same base version but different suffixes are still sorted
           lexicographically, resulting e.g. in prerelease tags appearing
           after the main release (e.g. "1.0-rc1" after "1.0"). This variable
           can be specified to determine the sorting order of tags with
           different suffixes.

           By specifying a single suffix in this variable, any tagname
           containing that suffix will appear before the corresponding main
           release. E.g. if the variable is set to "-rc", then all "1.0-rcX"
           tags will appear before "1.0". If specified multiple times, once
           per suffix, then the order of suffixes in the configuration will
           determine the sorting order of tagnames with those suffixes. E.g.
           if "-pre" appears before "-rc" in the configuration, then all
           "1.0-preX" tags will be listed before any "1.0-rcX" tags. The
           placement of the main release tag relative to tags with various
           suffixes can be determined by specifying the empty suffix among
           those other suffixes. E.g. if the suffixes "-rc", "", "-ck" and
           "-bfs" appear in the configuration in this order, then all
           "v4.8-rcX" tags are listed first, followed by "v4.8", then
           "v4.8-ckX" and finally "v4.8-bfsX".

           If more than one suffixes match the same tagname, then that tagname
           will be sorted according to the suffix which starts at the earliest
           position in the tagname. If more than one different matching
           suffixes start at that earliest position, then that tagname will be
           sorted according to the longest of those suffixes. The sorting
           order between different suffixes is undefined if they are in
           multiple config files.

       web.browser
           Specify a web browser that may be used by some commands. Currently
           only git-instaweb(1) and git-help(1) may use it.

       worktree.guessRemote
           If no branch is specified and neither -b nor -B nor --detach is
           used, then git worktree add defaults to creating a new branch from
           HEAD. If worktree.guessRemote is set to true, worktree add tries to
           find a remote-tracking branch whose name uniquely matches the new
           branch name. If such a branch exists, it is checked out and set as
           "upstream" for the new branch. If no such match can be found, it
           falls back to creating a new branch from the current HEAD.

BUGS
       When using the deprecated [section.subsection] syntax, changing a value
       will result in adding a multi-line key instead of a change, if the
       subsection is given with at least one uppercase character. For example
       when the config looks like

             [section.subsection]
               key = value1

       and running git config section.Subsection.key value2 will result in

             [section.subsection]
               key = value1
               key = value2
