The new name for an existing branch. The same restrictions as for
<branchname> apply.
+<count>::
+ By default the command shows all refs that match
+ `<pattern>`. This option makes it stop after showing
+ that many refs.
+
+<key>::
+ A field name to sort on. Prefix `-` to sort in descending
+ order of the value. When unspecified, `refname` is used. You
+ may use the --sort=<key> option multiple times, in which case
+ the last key becomes the primary key. See
+ linkgit:for-each-ref[1] for field name details.
