DESCRIPTION
`git reset --hard <upstream>` (or <newbase>).
The commits that were previously saved into the temporary area are
-then reapplied to the current branch, one by one, in order.
+then reapplied to the current branch, one by one, in order. Note that
+any commits in HEAD which introduce the same textual changes as a commit
+in HEAD..<upstream> are omitted (i.e., a patch already accepted upstream
+with a different commit message or timestamp will be skipped).
It is possible that a merge failure will prevent this process from being
completely automatic. You will have to resolve any such merge failure
The latter form is just a short-hand of `git checkout topic`
followed by `git rebase master`.
+If the upstream branch already contains a change you have made (e.g.,
+because you mailed a patch which was applied upstream), then that commit
+will be skipped. For example, running `git-rebase master` on the
+following history (in which A' and A introduce the same set of changes,
+but have different committer information):
+
+------------
+ A---B---C topic
+ /
+ D---E---A'---F master
+------------
+
+will result in:
+
+------------
+ B'---C' topic
+ /
+ D---E---A'---F master
+------------
+
Here is how you would transplant a topic branch based on one
branch to another, to pretend that you forked the topic branch
from the latter branch, using `rebase --onto`.
--skip::
Restart the rebasing process by skipping the current patch.
---merge::
+-m, \--merge::
Use merging strategies to rebase. When the recursive (default) merge
strategy is used, this allows rebase to be aware of renames on the
upstream side.
context exist they all must match. By default no context is
ever ignored.
+--whitespace=<nowarn|warn|error|error-all|strip>::
+ This flag is passed to the `git-apply` program
+ (see gitlink:git-apply[1]) that applies the patch.
+
-i, \--interactive::
Make a list of the commits which are about to be rebased. Let the
- user edit that list before rebasing.
+ user edit that list before rebasing. This mode can also be used to
+ split commits (see SPLITTING COMMITS below).
-p, \--preserve-merges::
Instead of ignoring merges, try to recreate them. This option
If you want to fold two or more commits into one, replace the command
"pick" with "squash" for the second and subsequent commit. If the
commits had different authors, it will attribute the squashed commit to
-the author of the last commit.
+the author of the first commit.
In both cases, or when a "pick" does not succeed (because of merge
errors), the loop will stop to let you fix things, and you can continue
$ git rebase -i -p --onto Q O

+SPLITTING COMMITS
+-----------------
+
+In interactive mode, you can mark commits with the action "edit". However,
+this does not necessarily mean that 'git rebase' expects the result of this
+edit to be exactly one commit. Indeed, you can undo the commit, or you can
+add other commits. This can be used to split a commit into two:
+
+- Start an interactive rebase with 'git rebase -i <commit>^', where
+ <commit> is the commit you want to split. In fact, any commit range
+ will do, as long as it contains that commit.
+
+- Mark the commit you want to split with the action "edit".
+
+- When it comes to editing that commit, execute 'git reset HEAD^'. The
+ effect is that the HEAD is rewound by one, and the index follows suit.
+ However, the working tree stays the same.
+
+- Now add the changes to the index that you want to have in the first
+ commit. You can use gitlink:git-add[1] (possibly interactively) and/or
+ gitlink:git-gui[1] to do that.
+
+- Commit the now-current index with whatever commit message is appropriate
+ now.
+
+- Repeat the last two steps until your working tree is clean.
+
+- Continue the rebase with 'git rebase --continue'.
+
+If you are not absolutely sure that the intermediate revisions are
+consistent (they compile, pass the testsuite, etc.) you should use
+gitlink:git-stash[1] to stash away the not-yet-committed changes
+after each commit, test, and amend the commit if fixes are necessary.
