From: sean Date: Wed, 26 Apr 2006 14:49:38 +0000 (-0400) Subject: Add --continue and --abort options to git-rebase. X-Git-Tag: v1.4.0-rc1~203^2 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=031321c654de3c19de45b2dacbdc990b5a694e34;p=git.git Add --continue and --abort options to git-rebase. git rebase [--onto ] [] git rebase --continue git rebase --abort Add "--continue" to restart the rebase process after manually resolving conflicts. The user is warned if there are still differences between the index and the working files. Add "--abort" to restore the original branch, and remove the .dotest working files. Some minor additions to the git-rebase documentation. [jc: fix that applies to the maintenance track has been dealt with separately.] Signed-off-by: Junio C Hamano --- diff --git a/Documentation/git-rebase.txt b/Documentation/git-rebase.txt index 4a7e67a4d..1b482abec 100644 --- a/Documentation/git-rebase.txt +++ b/Documentation/git-rebase.txt @@ -3,38 +3,54 @@ git-rebase(1) NAME ---- -git-rebase - Rebase local commits to new upstream head +git-rebase - Rebase local commits to a new head SYNOPSIS -------- 'git-rebase' [--onto ] [] +'git-rebase' --continue + +'git-rebase' --abort + DESCRIPTION ----------- -git-rebase applies to (or optionally to ) commits -from that do not appear in .
