| git-reflog(1) |
| ============= |
| |
| NAME |
| ---- |
| git-reflog - Manage reflog information |
| |
| |
| SYNOPSIS |
| -------- |
| [verse] |
| 'git reflog' <subcommand> <options> |
| |
| DESCRIPTION |
| ----------- |
| The command takes various subcommands, and different options |
| depending on the subcommand: |
| |
| [verse] |
| '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 linkgit: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 linkgit: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 linkgit:gitrevisions[7] 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. |
