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.
