6 git-rebase - Forward-port local commits to the updated upstream head
10 'git-rebase' [-v] [--merge] [-C<n>] [--onto <newbase>] <upstream> [<branch>]
12 'git-rebase' --continue | --skip | --abort
16 If <branch> is specified, git-rebase will perform an automatic
17 `git checkout <branch>` before doing anything else. Otherwise
18 it remains on the current branch.
20 All changes made by commits in the current branch but that are not
21 in <upstream> are saved to a temporary area. This is the same set
22 of commits that would be shown by `git log <upstream>..HEAD`.
24 The current branch is reset to <upstream>, or <newbase> if the
25 --onto option was supplied. This has the exact same effect as
26 `git reset --hard <upstream>` (or <newbase>).
28 The commits that were previously saved into the temporary area are
29 then reapplied to the current branch, one by one, in order.
31 It is possible that a merge failure will prevent this process from being
32 completely automatic. You will have to resolve any such merge failure
33 and run `git rebase --continue`. Another option is to bypass the commit
34 that caused the merge failure with `git rebase --skip`. To restore the
35 original <branch> and remove the .dotest working files, use the command
36 `git rebase --abort` instead.
38 Assume the following history exists and the current branch is "topic":
46 From this point, the result of either of the following commands:
50 git-rebase master topic
60 The latter form is just a short-hand of `git checkout topic`
61 followed by `git rebase master`.
63 Here is how you would transplant a topic branch based on one
64 branch to another, to pretend that you forked the topic branch
65 from the latter branch, using `rebase --onto`.
67 First let's assume your 'topic' is based on branch 'next'.
68 For example feature developed in 'topic' depends on some
69 functionality which is found in 'next'.
72 o---o---o---o---o master
74 o---o---o---o---o next
79 We would want to make 'topic' forked from branch 'master',
80 for example because the functionality 'topic' branch depend on
81 got merged into more stable 'master' branch, like this:
84 o---o---o---o---o master
88 o---o---o---o---o next
91 We can get this using the following command:
93 git-rebase --onto master next topic
96 Another example of --onto option is to rebase part of a
97 branch. If we have the following situation:
109 git-rebase --onto master topicA topicB
121 This is useful when topicB does not depend on topicA.
123 A range of commits could also be removed with rebase. If we have
124 the following situation:
127 E---F---G---H---I---J topicA
132 git-rebase --onto topicA~5 topicA~2 topicA
134 would result in the removal of commits F and G:
137 E---H'---I'---J' topicA
140 This is useful if F and G were flawed in some way, or should not be
141 part of topicA. Note that the argument to --onto and the <upstream>
142 parameter can be any valid commit-ish.
144 In case of conflict, git-rebase will stop at the first problematic commit
145 and leave conflict markers in the tree. You can use git diff to locate
146 the markers (<<<<<<) and make edits to resolve the conflict. For each
147 file you edit, you need to tell git that the conflict has been resolved,
148 typically this would be done with
151 git update-index <filename>
154 After resolving the conflict manually and updating the index with the
155 desired resolution, you can continue the rebasing process with
158 git rebase --continue
161 Alternatively, you can undo the git-rebase with
169 Starting point at which to create the new commits. If the
170 --onto option is not specified, the starting point is
171 <upstream>. May be any valid commit, and not just an
172 existing branch name.
175 Upstream branch to compare against. May be any valid commit,
176 not just an existing branch name.
179 Working branch; defaults to HEAD.
182 Restart the rebasing process after having resolved a merge conflict.
185 Restore the original branch and abort the rebase operation.
188 Restart the rebasing process by skipping the current patch.
191 Use merging strategies to rebase. When the recursive (default) merge
192 strategy is used, this allows rebase to be aware of renames on the
195 -s <strategy>, \--strategy=<strategy>::
196 Use the given merge strategy; can be supplied more than
197 once to specify them in the order they should be tried.
198 If there is no `-s` option, a built-in list of strategies
199 is used instead (`git-merge-recursive` when merging a single
200 head, `git-merge-octopus` otherwise). This implies --merge.
203 Display a diffstat of what changed upstream since the last rebase.
206 Ensure at least <n> lines of surrounding context match before
207 and after each change. When fewer lines of surrounding
208 context exist they all must match. By default no context is

215 When you rebase a branch, you are changing its history in a way that
216 will cause problems for anyone who already has a copy of the branch
217 in their repository and tries to pull updates from you. You should
218 understand the implications of using 'git rebase' on a repository that
221 When the git rebase command is run, it will first execute a "pre-rebase"
222 hook if one exists. You can use this hook to do sanity checks and
223 reject the rebase if it isn't appropriate. Please see the template
224 pre-rebase hook script for an example.
226 You must be in the top directory of your project to start (or continue)
227 a rebase. Upon completion, <branch> will be the current branch.
