31 git-reflog \- Manage reflog information
35 \fIgit reflog\fR <subcommand> <options>
40 The command takes various subcommands, and different options depending on the subcommand:
46 \fIgit reflog\fR [\fIshow\fR] [log\-options] [<ref>]
47 \fIgit reflog expire\fR [\-\-expire=<time>] [\-\-expire\-unreachable=<time>]
48 [\-\-rewrite] [\-\-updateref] [\-\-stale\-fix]
49 [\-\-dry\-run | \-n] [\-\-verbose] [\-\-all [\-\-single\-worktree] | <refs>\&...]
50 \fIgit reflog delete\fR [\-\-rewrite] [\-\-updateref]
51 [\-\-dry\-run | \-n] [\-\-verbose] ref@{specifier}\&...
52 \fIgit reflog exists\fR <ref>
59 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, \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\&.
61 This command manages the information recorded in the reflogs\&.
63 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\&.
65 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)\&.
67 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\&.
69 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\&.
71 .SS "Options for \fBshow\fR"
73 \fBgit reflog show\fR accepts any of the options accepted by \fBgit log\fR\&.
74 .SS "Options for \fBexpire\fR"
78 Process the reflogs of all references\&.
85 is specified, reflogs from all working trees are processed\&. This option limits the processing to reflogs from the current working tree only\&.
90 Prune entries older than the specified time\&. If this option is not specified, the expiration time is taken from the configuration setting
91 \fBgc\&.reflogExpire\fR, which in turn defaults to 90 days\&.
93 prunes entries regardless of their age;
94 \fB\-\-expire=never\fR
95 turns off pruning of reachable entries (but see
96 \fB\-\-expire\-unreachable\fR)\&.
99 \-\-expire\-unreachable=<time>
101 Prune entries older than
103 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
104 \fBgc\&.reflogExpireUnreachable\fR, which in turn defaults to 30 days\&.
105 \fB\-\-expire\-unreachable=all\fR
106 prunes unreachable entries regardless of their age;
107 \fB\-\-expire\-unreachable=never\fR
108 turns off early pruning of unreachable entries (but see
114 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\&.)
119 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\&.
124 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\&.
126 This computation involves traversing all the reachable objects, i\&.e\&. it has the same cost as
127 \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\&.
132 Do not actually prune any entries; just show what would have been pruned\&.
137 Print extra information on screen\&.
139 .SS "Options for \fBdelete\fR"
141 \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\&.
