GIT-REFLOG(1)                     Git Manual                     GIT-REFLOG(1)

NAME
       git-reflog - Manage reflog information

SYNOPSIS
       git reflog <subcommand> <options>

DESCRIPTION
       The command takes various subcommands, and different options depending
       on the subcommand:

           git reflog [show] [log-options] [<ref>]
           git reflog expire [--expire=<time>] [--expire-unreachable=<time>]
                   [--rewrite] [--updateref] [--stale-fix]
                   [--dry-run | -n] [--verbose] [--all [--single-worktree] | <refs>...]
           git reflog delete [--rewrite] [--updateref]
                   [--dry-run | -n] [--verbose] ref@{specifier}...
           git reflog exists <ref>

       Reference logs, or "reflogs", record when the tips of branches and
       other references were updated in the local repository. Reflogs are
       useful in various Git commands, to specify the old value of a
       reference. For example, HEAD@{2} means "where HEAD used to be two moves
       ago", master@{one.week.ago} means "where master used to point to one
       week ago in this local repository", and so on. See gitrevisions(7) for
       more details.

       This command manages the information recorded in the reflogs.

       The "show" subcommand (which is also the default, in the absence of any
       subcommands) shows the log of the reference provided in the
       command-line (or HEAD, by default). The reflog covers all recent
       actions, and in addition the HEAD reflog records branch switching. git
       reflog show is an alias for git log -g --abbrev-commit
       --pretty=oneline; see git-log(1) for more information.

       The "expire" subcommand prunes older reflog entries. Entries older than
       expire time, or entries older than expire-unreachable time and not
       reachable from the current tip, are removed from the reflog. This is
       typically not used directly by end users -- instead, see git-gc(1).

       The "delete" subcommand deletes single entries from the reflog. Its
       argument must be an exact entry (e.g. "git reflog delete master@{2}").
       This subcommand is also typically not used directly by end users.

       The "exists" subcommand checks whether a ref has a reflog. It exits
       with zero status if the reflog exists, and non-zero status if it does
       not.

OPTIONS
   Options for show
       git reflog show accepts any of the options accepted by git log.

   Options for expire
       --all
           Process the reflogs of all references.

       --single-worktree
           By default when --all is specified, reflogs from all working trees
           are processed. This option limits the processing to reflogs from
           the current working tree only.

       --expire=<time>
           Prune entries older than the specified time. If this option is not
           specified, the expiration time is taken from the configuration
           setting gc.reflogExpire, which in turn defaults to 90 days.
           --expire=all prunes entries regardless of their age; --expire=never
           turns off pruning of reachable entries (but see
           --expire-unreachable).

       --expire-unreachable=<time>
           Prune entries older than <time> that are not reachable from the
           current tip of the branch. If this option is not specified, the
           expiration time is taken from the configuration setting
           gc.reflogExpireUnreachable, which in turn defaults to 30 days.
           --expire-unreachable=all prunes unreachable entries regardless of
           their age; --expire-unreachable=never turns off early pruning of
           unreachable entries (but see --expire).

       --updateref
           Update the reference to the value of the top reflog entry (i.e.
           <ref>@{0}) if the previous top entry was pruned. (This option is
           ignored for symbolic references.)

       --rewrite
           If a reflog entry's predecessor is pruned, adjust its "old" SHA-1
           to be equal to the "new" SHA-1 field of the entry that now precedes
           it.

       --stale-fix
           Prune any reflog entries that point to "broken commits". A broken
           commit is a commit that is not reachable from any of the reference
           tips and that refers, directly or indirectly, to a missing commit,
           tree, or blob object.

           This computation involves traversing all the reachable objects,
           i.e. it has the same cost as git prune. It is primarily intended to
           fix corruption caused by garbage collecting using older versions of
           Git, which didn't protect objects referred to by reflogs.

       -n, --dry-run
           Do not actually prune any entries; just show what would have been
           pruned.

       --verbose
           Print extra information on screen.

   Options for delete
       git reflog delete accepts options --updateref, --rewrite, -n,
       --dry-run, and --verbose, with the same meanings as when they are used
       with expire.
