OPTIONS
-------
--keep-empty::
Keep the commits that do not change anything from its
parents in the result.
++
+See also INCOMPATIBLE OPTIONS below.
--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.
++
+See also INCOMPATIBLE OPTIONS below.
--skip::
Restart the rebasing process by skipping the current patch.
conflict happens, the side reported as 'ours' is the so-far rebased
series, starting with <upstream>, and 'theirs' is the working branch. In
other words, the sides are swapped.
++
+See also INCOMPATIBLE OPTIONS below.
-s <strategy>::
--strategy=<strategy>::
+
Because 'git rebase' replays each commit from the working branch
on top of the <upstream> branch using the given strategy, using
-the 'ours' strategy simply discards all patches from the <branch>,
+the 'ours' strategy simply empties all patches from the <branch>,
which makes little sense.
++
+See also INCOMPATIBLE OPTIONS below.
-X <strategy-option>::
--strategy-option=<strategy-option>::
This implies `--merge` and, if no strategy has been
specified, `-s recursive`. Note the reversal of 'ours' and
'theirs' as noted above for the `-m` option.
++
+See also INCOMPATIBLE OPTIONS below.
+
+--rerere-autoupdate::
+--no-rerere-autoupdate::
+ Allow the rerere mechanism to update the index with the
+ result of auto-conflict resolution if possible.
-S[<keyid>]::
--gpg-sign[=<keyid>]::
and after each change. When fewer lines of surrounding
context exist they all must match. By default no context is
ever ignored.
++
+See also INCOMPATIBLE OPTIONS below.
--f::
+--no-ff::
--force-rebase::
- Force a rebase even if the current branch is up to date and
- the command without `--force` would return without doing anything.
+-f::
+ Individually replay all rebased commits instead of fast-forwarding
+ over the unchanged ones. This ensures that the entire history of
+ the rebased branch is composed of new commits.
+
-You may find this (or --no-ff with an interactive rebase) helpful after
-reverting a topic branch merge, as this option recreates the topic branch with
-fresh commits so it can be remerged successfully without needing to "revert
-the reversion" (see the
-link:howto/revert-a-faulty-merge.html[revert-a-faulty-merge How-To] for details).

These flags are passed to 'git am' to easily change the dates
of the rebased commits (see linkgit:git-am[1]).
- Incompatible with the --interactive option.
++
+See also INCOMPATIBLE OPTIONS below.
--signoff::
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

-i::
--interactive::
The commit list format can be changed by setting the configuration option
rebase.instructionFormat. A customized instruction format will automatically
have the long commit hash prepended to the format.
++
+See also INCOMPATIBLE OPTIONS below.
-r::
--rebase-merges[=(rebase-cousins|no-rebase-cousins)]::
+
By default, or when `no-rebase-cousins` was specified, commits which do not
have `<upstream>` as direct ancestor will keep their original branch point,
-i.e. commits that would be excluded by gitlink:git-log[1]'s
+i.e. commits that would be excluded by linkgit:git-log[1]'s
`--ancestry-path` option will keep their original ancestry by default. If
the `rebase-cousins` mode is turned on, such commits are instead rebased
onto `<upstream>` (or `<onto>`, if specified).
+
-The `--rebase-merges` mode is similar in spirit to `--preserve-merges`, but
-in contrast to that option works well in interactive rebases: commits can be

It is currently only possible to recreate the merge commits using the
`recursive` merge strategy; Different merge strategies can be used only via
explicit `exec git merge -s <strategy> [...]` commands.

--preserve-merges::
- Recreate merge commits instead of flattening the history by replaying

+ instead of flattening the history by replaying commits a merge commit

This uses the `--interactive` machinery internally, but combining it
with the `--interactive` option explicitly is generally not a good
idea unless you know what you are doing (see BUGS below).

-x <cmd>::
--exec <cmd>::
+
This uses the `--interactive` machinery internally, but it can be run
without an explicit `--interactive`.
++
+See also INCOMPATIBLE OPTIONS below.
--root::
Rebase all commits reachable from <branch>, instead of
When used together with both --onto and --preserve-merges,
'all' root commits will be rewritten to have <newbase> as parent
instead.

too. The recommended way to create fixup/squash commits is by using
the `--fixup`/`--squash` options of linkgit:git-commit[1].
+
-This option is only valid when the `--interactive` option is used.
-+
If the `--autosquash` option is enabled by default using the
configuration variable `rebase.autoSquash`, this option can be
used to override and disable this setting.
++
+See also INCOMPATIBLE OPTIONS below.
--autostash::
--no-autostash::
with care: the final stash application after a successful
rebase might result in non-trivial conflicts.
---no-ff::
- With --interactive, cherry-pick all rebased commits instead of
- fast-forwarding over the unchanged ones. This ensures that the
- entire history of the rebased branch is composed of new commits.

-Without --interactive, this is a synonym for --force-rebase.

+BEHAVIORAL DIFFERENCES
+-----------------------
+
+There are some subtle differences how the backends behave.
+
+Empty commits
+~~~~~~~~~~~~~
+
+The am backend drops any "empty" commits, regardless of whether the
+commit started empty (had no changes relative to its parent to
+start with) or ended empty (all changes were already applied
+upstream in other commits).
+
+The interactive backend drops commits by default that
+started empty and halts if it hits a commit that ended up empty.
+The `--keep-empty` option exists for the interactive backend to allow
+it to keep commits that started empty.
+
+Directory rename detection
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Directory rename heuristics are enabled in the merge and interactive
+backends. Due to the lack of accurate tree information, directory
+rename detection is disabled in the am backend.

the files and/or the commit message, amend the commit, and continue
rebasing.
+To interrupt the rebase (just like an "edit" command would do, but without
+cherry-picking any commit first), use the "break" command.

If you just want to edit the commit message for a commit, replace the
command "pick" with the command "reword".

refuses to overwrite untracked files. If the `reset` command fails, it is
rescheduled immediately, with a helpful message how to edit the todo list

list manually and contains a typo).

this, an `exec` command can be used to call `git merge` explicitly,
using the fact that the labels are worktree-local refs (the ref
`refs/rewritten/onto` would correspond to the label `onto`, for example).
BUGS
----

-represent the topology of the revision graph. Editing commits and
-rewording their commit messages should work fine, but attempts to
-reorder commits tend to produce counterintuitive results. Use
-`--rebase-merges` in such scenarios instead.
