INCOMPATIBLE OPTIONS
--------------------
-git-rebase has many flags that are incompatible with each other,
-predominantly due to the fact that it has three different underlying
-implementations:
-
- * one based on linkgit:git-am[1] (the default)
- * one based on git-merge-recursive (merge backend)
- * one based on linkgit:git-cherry-pick[1] (interactive backend)
-
-Flags only understood by the am backend:
+The following options:
* --committer-date-is-author-date
* --ignore-date
* --ignore-whitespace
* -C
-Flags understood by both merge and interactive backends:
+are incompatible with the following options:
* --merge
* --strategy
* --strategy-option
* --allow-empty-message
-
-Flags only understood by the interactive backend:
-
* --[no-]autosquash
* --rebase-merges
* --preserve-merges
* --edit-todo
* --root when used in combination with --onto
-Other incompatible flag pairs:
+In addition, the following pairs of options are incompatible:
* --preserve-merges and --interactive
* --preserve-merges and --signoff
