     git-reflog - Manage reflog information

     git reflog <subcommand> <options>

     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-

     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
     gitrevisions(5) 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}").

         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.

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

         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

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

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

         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.
