NAME
git-init - Create an empty Git repository or reinitialize an existing
one
SYNOPSIS
git init [-q | --quiet] [--bare] [--template=<template_directory>]
[--separate-git-dir <git dir>] [--object-format=<format]
[--shared[=<permissions>]] [directory]
DESCRIPTION
This command creates an empty Git repository - basically a .git
directory with subdirectories for objects, refs/heads, refs/tags, and
template files. An initial HEAD file that references the HEAD of the
master branch is also created.
If the $GIT_DIR environment variable is set then it specifies a path to
use instead of ./.git for the base of the repository.
If the object storage directory is specified via the
$GIT_OBJECT_DIRECTORY environment variable then the sha1 directories
are created underneath - otherwise the default $GIT_DIR/objects
directory is used.
Running git init in an existing repository is safe. It will not
overwrite things that are already there. The primary reason for
rerunning git init is to pick up newly added templates (or to move the
repository to another place if --separate-git-dir is given).
OPTIONS
-q, --quiet
Only print error and warning messages; all other output will be
suppressed.
--bare
Create a bare repository. If GIT_DIR environment is not set, it is
set to the current working directory.
--object-format=<format>
Specify the given object format (hash algorithm) for the
repository. The valid values are sha1 and (if enabled) sha256.
sha1 is the default.
--template=<template_directory>
Specify the directory from which templates will be used. (See the
"TEMPLATE DIRECTORY" section below.)
--separate-git-dir=<git dir>
Instead of initializing the repository as a directory to either
$GIT_DIR or ./.git/, create a text file there containing the path
to the actual repository. This file acts as filesystem-agnostic Git
symbolic link to the repository.
If this is reinitialization, the repository will be moved to the
specified path.
--shared[=(false|true|umask|group|all|world|everybody|0xxx)]
Specify that the Git repository is to be shared amongst several
users. This allows users belonging to the same group to push into
that repository. When specified, the config variable
"core.sharedRepository" is set so that files and directories under
$GIT_DIR are created with the requested permissions. When not
specified, Git will use permissions reported by umask(2).
The option can have the following values, defaulting to group if no
value is given:
umask (or false)
Use permissions reported by umask(2). The default, when
--shared is not specified.
group (or true)
Make the repository group-writable, (and g+sx, since the git
group may be not the primary group of all users). This is used
to loosen the permissions of an otherwise safe umask(2) value.
Note that the umask still applies to the other permission bits
(e.g. if umask is 0022, using group will not remove read
privileges from other (non-group) users). See 0xxx for how to
exactly specify the repository permissions.
all (or world or everybody)
Same as group, but make the repository readable by all users.
0xxx
0xxx is an octal number and each file will have mode 0xxx.
0xxx will override users' umask(2) value (and not only loosen
permissions as group and all does). 0640 will create a
repository which is group-readable, but not group-writable or
accessible to others. 0660 will create a repo that is readable
and writable to the current user and group, but inaccessible to
others.
By default, the configuration flag receive.denyNonFastForwards is
enabled in shared repositories, so that you cannot force a non
fast-forwarding push into it.
If you provide a directory, the command is run inside it. If this
directory does not exist, it will be created.
TEMPLATE DIRECTORY
Files and directories in the template directory whose name do not start
with a dot will be copied to the $GIT_DIR after it is created.
The template directory will be one of the following (in order):
o the argument given with the --template option;
o the contents of the $GIT_TEMPLATE_DIR environment variable;
o the init.templateDir configuration variable; or
o the default template directory: /usr/share/git-core/templates.
The default template directory includes some directory structure,
suggested "exclude patterns" (see gitignore(5)), and sample hook files.
The sample hooks are all disabled by default. To enable one of the
sample hooks rename it by removing its .sample suffix.
See githooks(5) for more general info on hook execution.
EXAMPLES
Start a new Git repository for an existing code base
$ cd /path/to/my/codebase
$ git init (1)
$ git add . (2)
$ git commit (3)
1. Create a /path/to/my/codebase/.git directory.
2. Add all existing files to the index.
3. Record the pristine state as the first commit in the history.
