SYNOPSIS
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>
DESCRIPTION
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 "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 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 settinggc.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.
