Reflogs are useful in various Git commands, to specify the old value of a reference\&. For example, \fBHEAD@{2}\fR means "where HEAD used to be two moves ago", \fBmaster@{one\&.week\&.ago}\fR means "where master used to point to one week ago in this local repository", and so on\&. See \fBgitrevisions\fR(7) for more details\&. .sp This command manages the information recorded in the reflogs\&. .sp 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 \fBHEAD\fR, by default)\&. The reflog covers all recent actions, and in addition the \fBHEAD\fR reflog records branch switching\&. \fBgit reflog show\fR is an alias for \fBgit log \-g \-\-abbrev\-commit \-\-pretty=oneline\fR; see \fBgit-log\fR(1) for more information\&. .sp The "expire" subcommand prunes older reflog entries\&. Entries older than \fBexpire\fR time, or entries older than \fBexpire\-unreachable\fR time and not reachable from the current tip, are removed from the reflog\&. This is typically not used directly by end users \(em instead, see \fBgit-gc\fR(1)\&. .sp The "delete" subcommand deletes single entries from the reflog\&. Its argument must be an \fIexact\fR entry (e\&.g\&. "\fBgit reflog delete master@{2}\fR")\&. This subcommand is also typically not used directly by end users\&. .sp 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\&. .SH "OPTIONS" .SS "Options for \fBshow\fR" .sp \fBgit reflog show\fR accepts any of the options accepted by \fBgit log\fR\&. .SS "Options for \fBexpire\fR" .PP \-\-all .RS 4 Process the reflogs of all references\&. .RE .PP \-\-expire=<time> .RS 4 Prune entries older than the specified time\&. If this option is not specified, the expiration time is taken from the configuration setting \fBgc\&.reflogExpire\fR, which in turn defaults to 90 days\&. \fB\-\-expire=all\fR prunes entries regardless of their age; \fB\-\-expire=never\fR turns off pruning of reachable entries (but see \fB\-\-expire\-unreachable\fR)\&. .RE .PP \-\-expire\-unreachable=<time> .RS 4 Prune entries older than \fB<time>\fR 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 \fBgc\&.reflogExpireUnreachable\fR, which in turn defaults to 30 days\&. \fB\-\-expire\-unreachable=all\fR prunes unreachable entries regardless of their age; \fB\-\-expire\-unreachable=never\fR turns off early pruning of unreachable entries (but see \fB\-\-expire\fR)\&. .RE .PP \-\-updateref .RS 4 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\&.) .RE .PP \-\-rewrite .RS 4 If a reflog entry\(cqs predecessor is pruned, adjust its "old" SHA\-1 to be equal to the "new" SHA\-1 field of the entry that now precedes it\&. .RE .PP \-\-stale\-fix .RS 4 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\&. .sp This computation involves traversing all the reachable objects, i\&.e\&. it has the same cost as \fIgit prune\fR\&. It is primarily intended to fix corruption caused by garbage collecting using older versions of Git, which didn\(cqt protect objects referred to by reflogs\&. .RE .PP \-n, \-\-dry\-run .RS 4 Do not actually prune any entries; just show what would have been pruned\&. .RE .PP \-\-verbose .RS 4 Print extra information on screen\&. .RE .SS "Options for \fBdelete\fR" .sp \fBgit reflog delete\fR accepts options \fB\-\-updateref\fR, \fB\-\-rewrite\fR, \fB\-n\fR, \fB\-\-dry\-run\fR, and \fB\-\-verbose\fR, with the same meanings as when they are used with \fBexpire\fR\&. .SH "GIT" .sp Part of the \fBgit\fR(1) suite
