bffd750a | 6 | USAGE='[--interactive | -i] [-v] [--force-rebase | -f] [--no-ff] [--onto <newbase>] (<upstream>|--root) [<branch>] [--quiet | -q]' |
031321c6 SE |
7 | LONG_USAGE='git-rebase replaces <branch> with a new branch of the |
8 | same name. When the --onto option is provided the new branch starts | |
9 | out with a HEAD equal to <newbase>, otherwise it is equal to <upstream> | |
10 | It then attempts to create a new commit for each commit from the original | |
11 | <branch> that does not exist in the <upstream> branch. | |

031321c6 SE |
13 | It is possible that a merge failure will prevent this process from being |
14 | completely automatic. You will have to resolve any such merge failure | |
cc120056 SE |
15 | and run git rebase --continue. Another option is to bypass the commit |
16 | that caused the merge failure with git rebase --skip. To restore the | |
51ef1daa JS |
17 | original <branch> and remove the .git/rebase-apply working files, use the |
18 | command git rebase --abort instead. | |
69a60af5 | 19 | |
031321c6 | 20 | Note that if <branch> is not specified on the command line, the |
702088af | 21 | currently checked out branch is used. |
