               [--dry-run | -n] [--verbose] <ref>@{<specifier>}...
       git reflog exists <ref>

DESCRIPTION         top

       This command manages the information recorded in the reflogs.

       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.

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

       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 "list" subcommand lists all refs which have a corresponding
       reflog.

       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         top

   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.
