5 # SHORT DESCRIPTION
7 # This script makes it easy to fix up commits in the middle of a series,
8 # and rearrange commits.
10 # The original idea comes from Eric W. Biederman, in
11 # http://article.gmane.org/gmane.comp.version-control.git/22407

14 OPTIONS_SPEC="\
15 git-rebase [-i] [options] [--] <upstream> [<branch>]
16 git-rebase [-i] (--continue | --abort | --skip)
18 Available options are
19 v,verbose display a diffstat of what changed upstream
20 onto= rebase onto given branch instead of upstream
21 p,preserve-merges try to recreate merges instead of ignoring them
22 s,strategy= use the given merge strategy
23 m,merge always used (no-op)
24 i,interactive always used (no-op)
25 Actions:
26 continue continue rebasing process
27 abort abort rebasing process and restore original branch
28 skip skip current patch and continue rebasing process
29 no-verify override pre-rebase hook from stopping the operation
30 root rebase all reachable commmits up to the root(s)
