DESCRIPTION
-----------
Keep the commits that do not change anything from its
parents in the result.
+--allow-empty-message::
+ By default, rebasing commits with an empty message will fail.
+ This option overrides that behavior, allowing commits with empty
+ messages to be rebased.
+
--skip::
Restart the rebasing process by skipping the current patch.
--edit-todo::
Edit the todo list during an interactive rebase.
+--show-current-patch::
+ Show the current patch in an interactive rebase or when rebase
+ is stopped because of conflicts. This is the equivalent of
+ `git show REBASE_HEAD`.
+
-m::
--merge::
Use merging strategies to rebase. When the recursive (default) merge
Incompatible with the --interactive option.
--signoff::
- This flag is passed to 'git am' to sign off all the rebased
- commits (see linkgit:git-am[1]). Incompatible with the
- --interactive option.
+ Add a Signed-off-by: trailer to all the rebased commits. Note
+ that if `--interactive` is given then only commits marked to be
+ picked, edited or reworded will have the trailer added. Incompatible
+ with the `--preserve-merges` option.
