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

       Reflog is a mechanism to record when the tip of branches are updated. This command is to manage the information recorded in it.

       The subcommand "expire" is used to prune 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 the end users -- instead,
       see git-gc(1).

       The subcommand "show" (which is also the default, in the absence of any subcommands) will take all the normal log options, and show the log
       of the reference provided in the command-line (or HEAD, by default). The reflog will cover all recent actions (HEAD reflog records branch
       switching as well). It is an alias for git log -g --abbrev-commit --pretty=oneline; see git-log(1).

       The reflog is 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", and so on. See git-rev-parse(1) for more
       details.

       To delete single entries from the reflog, use the subcommand "delete" and specify the exact entry (e.g. "git reflog delete master@{2}").

OPTIONS

       --stale-fix
	   This revamps the logic -- the definition of "broken commit" becomes: a commit that is not reachable from any of the refs and there is a
	   missing object among the commit, tree, or blob objects reachable from it that is not reachable from any of the refs.

	   This computation involves traversing all the reachable objects, i.e. it has the same cost as git prune. Fortunately, once this is run,
	   we should not have to ever worry about missing objects, because the current prune and pack-objects know about reflogs and protect
	   objects referred by them.

       --expire=<time>
	   Entries older than this time are pruned. Without the option it is taken from configuration gc.reflogExpire, which in turn defaults to
	   90 days.

       --expire-unreachable=<time>
	   Entries older than this time and not reachable from the current tip of the branch are pruned. Without the option it is taken from
	   configuration gc.reflogExpireUnreachable, which in turn defaults to 30 days.

       --all
	   Instead of listing <refs> explicitly, prune all refs.

       --updateref
	   Update the ref with the sha1 of the top reflog entry (i.e. <ref>@{0}) after expiring or deleting.

       --rewrite
	   While expiring or deleting, adjust each reflog entry to ensure that the old sha1 field points to the new sha1 field of the previous
	   entry.

       --verbose
	   Print extra information on screen.
