Reflog is a mechanism to record when the tip of branches are
updated. This command is to manage the information recorded in it.
Entries older than `expire` time, or entries older than
`expire-unreachable` time and are not reachable from the current
tip, are removed from the reflog. This is typically not used
-directly by the end users -- instead, see gitlink:git-gc[1].
+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
-`HEAD`, which will cover all recent actions, including branch switches.
-It is basically an alias for 'git log -g --abbrev-commit
---pretty=oneline', see gitlink:git-log[1].

+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`;

+
+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: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
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
+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.
--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.
