Otherwise it remains on the current branch\&. .sp If \fB\fR is not specified, the upstream configured in \fBbranch\&.\&.remote\fR and \fBbranch\&.\&.merge\fR options will be used (see \fBgit-config\fR(1) for details) and the \fB\-\-fork\-point\fR option is assumed\&. If you are currently not on any branch or if the current branch does not have a configured upstream, the rebase will abort\&. .sp All changes made by commits in the current branch but that are not in \fB\fR are saved to a temporary area\&. This is the same set of commits that would be shown by \fBgit log \&.\&.HEAD\fR; or by \fBgit log \*(Aqfork_point\*(Aq\&.\&.HEAD\fR, if \fB\-\-fork\-point\fR is active (see the description on \fB\-\-fork\-point\fR below); or by \fBgit log HEAD\fR, if the \fB\-\-root\fR option is specified\&. .sp The current branch is reset to \fB\fR or \fB\fR if the \fB\-\-onto\fR option was supplied\&. This has the exact same effect as \fBgit reset \-\-hard \fR (or \fB\fR)\&. \fBORIG_HEAD\fR is set to point at the tip of the branch before the reset\&. .if n \{\ .sp .\} .RS 4 .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .ps +1 \fBNote\fR .ps -1 .br .sp \fBORIG_HEAD\fR is not guaranteed to still point to the previous branch tip at the end of the rebase if other commands that write that pseudo\-ref (e\&.g\&. \fBgit reset\fR) are used during the rebase\&. The previous branch tip, however, is accessible using the reflog of the current branch (i\&.e\&. \fB@{1}\fR, see \fBgitrevisions\fR(7))\&. .sp .5v .RE .sp The commits that were previously saved into the temporary area are then reapplied to the current branch, one by one, in order\&. Note that any commits in \fBHEAD\fR which introduce the same textual changes as a commit in \fBHEAD\&.\&.\fR are omitted (i\&.e\&., a patch already accepted upstream with a different commit message or timestamp will be skipped)\&. .sp It is possible that a merge failure will prevent this process from being completely automatic\&. You will have to resolve any such merge failure and run \fBgit rebase \-\-continue\fR\&. Another option is to bypass the commit that caused the merge failure with \fBgit rebase \-\-skip\fR\&. To check out the original \fB\fR and remove the \fB\&.git/rebase\-apply\fR working files, use the command \fBgit rebase \-\-abort\fR instead\&. .sp Assume the following history exists and the current branch is "topic": .sp .if n \{\ .RS 4 .\} .nf A\-\-\-B\-\-\-C topic / D\-\-\-E\-\-\-F\-\-\-G master .fi .if n \{\ .RE .\} .sp .sp From this point, the result of either of the following commands: .sp .if n \{\ .RS 4 .\} .nf git rebase master git rebase master topic .fi .if n \{\ .RE .\} .sp would be: .sp .if n \{\ .RS 4 .\} .nf A\*(Aq\-\-B\*(Aq\-\-C\*(Aq topic / D\-\-\-E\-\-\-F\-\-\-G master .fi .if n \{\ .RE .\} .sp .sp \fBNOTE:\fR The latter form is just a short\-hand of \fBgit checkout topic\fR followed by \fBgit rebase master\fR\&. When rebase exits \fBtopic\fR will remain the checked\-out branch\&. .sp 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 and warnings will be issued (if the \fImerge\fR backend is used)\&. For example, running \fBgit rebase master\fR on the following history (in which \fBA\*(Aq\fR and \fBA\fR introduce the same set of changes, but have different committer information): .sp .if n \{\ .RS 4 .\} .nf A\-\-\-B\-\-\-C topic / D\-\-\-E\-\-\-A\*(Aq\-\-\-F master .fi .if n \{\ .RE .\} .sp .sp will result in: .sp .if n \{\ .RS 4 .\} .nf B\*(Aq\-\-\-C\*(Aq topic / D\-\-\-E\-\-\-A\*(Aq\-\-\-F master .fi .if n \{\ .RE .\} .sp .sp 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 \fBrebase \-\-onto\fR\&. .sp First let\(cqs assume your \fItopic\fR is based on branch \fInext\fR\&. For example, a feature developed in \fItopic\fR depends on some functionality which is found in \fInext\fR\&. .sp .if n \{\ .RS 4 .\} .nf o\-\-\-o\-\-\-o\-\-\-o\-\-\-o master \e o\-\-\-o\-\-\-o\-\-\-o\-\-\-o next \e o\-\-\-o\-\-\-o topic .fi .if n \{\ .RE .\} .sp .sp We want to make \fItopic\fR forked from branch \fImaster\fR; for example, because the functionality on which \fItopic\fR depends was merged into the more stable \fImaster\fR branch\&. We want our tree to look like this: .sp .if n \{\ .RS 4 .\} .nf o\-\-\-o\-\-\-o\-\-\-o\-\-\-o master | \e | o\*(Aq\-\-o\*(Aq\-\-o\*(Aq topic \e o\-\-\-o\-\-\-o\-\-\-o\-\-\-o next .fi .if n \{\ .RE .\} .sp .sp We can get this using the following command: .sp .if n \{\ .RS 4 .\} .nf git rebase \-\-onto master next topic .fi .if n \{\ .RE .\} .sp Another example of \-\-onto option is to rebase part of a branch\&. If we have the following situation: .sp .if n \{\ .RS 4 .\} .nf H\-\-\-I\-\-\-J topicB / E\-\-\-F\-\-\-G topicA / A\-\-\-B\-\-\-C\-\-\-D master .fi .if n \{\ .RE .\} .sp .sp then the command .sp .if n \{\ .RS 4 .\} .nf git rebase \-\-onto master topicA topicB .fi .if n \{\ .RE .\} .sp would result in: .sp .if n \{\ .RS 4 .\} .nf H\*(Aq\-\-I\*(Aq\-\-J\*(Aq topicB / | E\-\-\-F\-\-\-G topicA |/ A\-\-\-B\-\-\-C\-\-\-D master .fi .if n \{\ .RE .\} .sp .sp This is useful when topicB does not depend on topicA\&. .sp A range of commits could also be removed with rebase\&. If we have the following situation: .sp .if n \{\ .RS 4 .\} .nf E\-\-\-F\-\-\-G\-\-\-H\-\-\-I\-\-\-J topicA .fi .if n \{\ .RE .\} .sp .sp then the command .sp .if n \{\ .RS 4 .\} .nf git rebase \-\-onto topicA~5 topicA~3 topicA .fi .if n \{\ .RE .\} .sp would result in the removal of commits F and G: .sp .if n \{\ .RS 4 .\} .nf E\-\-\-H\*(Aq\-\-\-I\*(Aq\-\-\-J\*(Aq topicA .fi .if n \{\ .RE .\} .sp .sp This is useful if F and G were flawed in some way, or should not be part of topicA\&. Note that the argument to \fB\-\-onto\fR and the \fB\fR parameter can be any valid commit\-ish\&. .sp In case of conflict, \fBgit rebase\fR will stop at the first problematic commit and leave conflict markers in the tree\&. You can use \fBgit diff\fR to locate the markers (<<<<<<) and make edits to resolve the conflict\&. For each file you edit, you need to tell Git that the conflict has been resolved, typically this would be done with .sp .if n \{\ .RS 4 .\} .nf git add .fi .if n \{\ .RE .\} .sp After resolving the conflict manually and updating the index with the desired resolution, you can continue the rebasing process with .sp .if n \{\ .RS 4 .\} .nf git rebase \-\-continue .fi .if n \{\ .RE .\} .sp Alternatively, you can undo the \fIgit rebase\fR with .sp .if n \{\ .RS 4 .\} .nf git rebase \-\-abort .fi .if n \{\ .RE .\} .SH "MODE OPTIONS" .sp The options in this section cannot be used with any other option, including not with each other: .PP \-\-continue .RS 4 Restart the rebasing process after having resolved a merge conflict\&. .RE .PP \-\-skip .RS 4 Restart the rebasing process by skipping the current patch\&. .RE .PP \-\-abort .RS 4 Abort the rebase operation and reset HEAD to the original branch\&. If \fB\fR was provided when the rebase operation was started, then \fBHEAD\fR will be reset to \fB\fR\&. Otherwise \fBHEAD\fR will be reset to where it was when the rebase operation was started\&. .RE .PP \-\-quit .RS 4 Abort the rebase operation but \fBHEAD\fR is not reset back to the original branch\&. The index and working tree are also left unchanged as a result\&. If a temporary stash entry was created using \fB\-\-autostash\fR, it will be saved to the stash list\&. .RE .PP \-\-edit\-todo .RS 4 Edit the todo list during an interactive rebase\&. .RE .PP \-\-show\-current\-patch .RS 4 Show the current patch in an interactive rebase or when rebase is stopped because of conflicts\&. This is the equivalent of \fBgit show REBASE_HEAD\fR\&. .RE .SH "OPTIONS" .PP \-\-onto .RS 4 Starting point at which to create the new commits\&. If the \fB\-\-onto\fR option is not specified, the starting point is \fB\fR\&. May be any valid commit, and not just an existing branch name\&. .sp As a special case, you may use "A\&.\&.\&.B" as a shortcut for the merge base of A and B if there is exactly one merge base\&. You can leave out at most one of A and B, in which case it defaults to HEAD\&. .RE .PP \-\-keep\-base .RS 4 Set the starting point at which to create the new commits to the merge base of \fB\fR and \fB\fR\&. Running \fBgit rebase \-\-keep\-base \fR is equivalent to running \fBgit rebase \-\-reapply\-cherry\-picks \-\-no\-fork\-point \-\-onto \&.\&.\&. \fR\&. .sp This option is useful in the case where one is developing a feature on top of an upstream branch\&. While the feature is being worked on, the upstream branch may advance and it may not be the best idea to keep rebasing on top of the upstream but to keep the base commit as\-is\&. As the base commit is unchanged this option implies \fB\-\-reapply\-cherry\-picks\fR to avoid losing commits\&. .sp Although both this option and \fB\-\-fork\-point\fR find the merge base between \fB\fR and \fB\fR, this option uses the merge base as the \fIstarting point\fR on which new commits will be created, whereas \fB\-\-fork\-point\fR uses the merge base to determine the \fIset of commits\fR which will be rebased\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP .RS 4 Upstream branch to compare against\&. May be any valid commit, not just an existing branch name\&. Defaults to the configured upstream for the current branch\&. .RE .PP .RS 4 Working branch; defaults to \fBHEAD\fR\&. .RE .PP \-\-apply .RS 4 Use applying strategies to rebase (calling \fBgit\-am\fR internally)\&. This option may become a no\-op in the future once the merge backend handles everything the apply one does\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-empty=(drop|keep|ask) .RS 4 How to handle commits that are not empty to start and are not clean cherry\-picks of any upstream commit, but which become empty after rebasing (because they contain a subset of already upstream changes)\&. With drop (the default), commits that become empty are dropped\&. With keep, such commits are kept\&. With ask (implied by \fB\-\-interactive\fR), the rebase will halt when an empty commit is applied allowing you to choose whether to drop it, edit files more, or just commit the empty changes\&. Other options, like \fB\-\-exec\fR, will use the default of drop unless \fB\-i\fR/\fB\-\-interactive\fR is explicitly specified\&. .sp Note that commits which start empty are kept (unless \fB\-\-no\-keep\-empty\fR is specified), and commits which are clean cherry\-picks (as determined by \fBgit log \-\-cherry\-mark \&.\&.\&.\fR) are detected and dropped as a preliminary step (unless \fB\-\-reapply\-cherry\-picks\fR or \fB\-\-keep\-base\fR is passed)\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-no\-keep\-empty, \-\-keep\-empty .RS 4 Do not keep commits that start empty before the rebase (i\&.e\&. that do not change anything from its parent) in the result\&. The default is to keep commits which start empty, since creating such commits requires passing the \fB\-\-allow\-empty\fR override flag to \fBgit commit\fR, signifying that a user is very intentionally creating such a commit and thus wants to keep it\&. .sp Usage of this flag will probably be rare, since you can get rid of commits that start empty by just firing up an interactive rebase and removing the lines corresponding to the commits you don\(cqt want\&. This flag exists as a convenient shortcut, such as for cases where external tools generate many empty commits and you want them all removed\&. .sp For commits which do not start empty but become empty after rebasing, see the \fB\-\-empty\fR flag\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-reapply\-cherry\-picks, \-\-no\-reapply\-cherry\-picks .RS 4 Reapply all clean cherry\-picks of any upstream commit instead of preemptively dropping them\&. (If these commits then become empty after rebasing, because they contain a subset of already upstream changes, the behavior towards them is controlled by the \fB\-\-empty\fR flag\&.) .sp In the absence of \fB\-\-keep\-base\fR (or if \fB\-\-no\-reapply\-cherry\-picks\fR is given), these commits will be automatically dropped\&. Because this necessitates reading all upstream commits, this can be expensive in repositories with a large number of upstream commits that need to be read\&. When using the \fImerge\fR backend, warnings will be issued for each dropped commit (unless \fB\-\-quiet\fR is given)\&. Advice will also be issued unless \fBadvice\&.skippedCherryPicks\fR is set to false (see \fBgit-config\fR(1))\&. .sp \fB\-\-reapply\-cherry\-picks\fR allows rebase to forgo reading all upstream commits, potentially improving performance\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-allow\-empty\-message .RS 4 No\-op\&. Rebasing commits with an empty message used to fail and this option would override that behavior, allowing commits with empty messages to be rebased\&. Now commits with an empty message do not cause rebasing to halt\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-m, \-\-merge .RS 4 Using merging strategies to rebase (default)\&. .sp Note that a rebase merge works by replaying each commit from the working branch on top of the \fB\fR branch\&. Because of this, when a merge conflict happens, the side reported as \fIours\fR is the so\-far rebased series, starting with \fB\fR, and \fItheirs\fR is the working branch\&. In other words, the sides are swapped\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-s , \-\-strategy= .RS 4 Use the given merge strategy, instead of the default \fBort\fR\&. This implies \fB\-\-merge\fR\&. .sp Because \fBgit rebase\fR replays each commit from the working branch on top of the \fB\fR branch using the given strategy, using the \fBours\fR strategy simply empties all patches from the \fB\fR, which makes little sense\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-X , \-\-strategy\-option= .RS 4 Pass the through to the merge strategy\&. This implies \fB\-\-merge\fR and, if no strategy has been specified, \fB\-s ort\fR\&. Note the reversal of \fIours\fR and \fItheirs\fR as noted above for the \fB\-m\fR option\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-rerere\-autoupdate, \-\-no\-rerere\-autoupdate .RS 4 After the rerere mechanism reuses a recorded resolution on the current conflict to update the files in the working tree, allow it to also update the index with the result of resolution\&. \fB\-\-no\-rerere\-autoupdate\fR is a good way to double\-check what \fBrerere\fR did and catch potential mismerges, before committing the result to the index with a separate \fBgit add\fR\&. .RE .PP \-S[], \-\-gpg\-sign[=], \-\-no\-gpg\-sign .RS 4 GPG\-sign commits\&. The \fBkeyid\fR argument is optional and defaults to the committer identity; if specified, it must be stuck to the option without a space\&. \fB\-\-no\-gpg\-sign\fR is useful to countermand both \fBcommit\&.gpgSign\fR configuration variable, and earlier \fB\-\-gpg\-sign\fR\&. .RE .PP \-q, \-\-quiet .RS 4 Be quiet\&. Implies \fB\-\-no\-stat\fR\&. .RE .PP \-v, \-\-verbose .RS 4 Be verbose\&. Implies \fB\-\-stat\fR\&. .RE .PP \-\-stat .RS 4 Show a diffstat of what changed upstream since the last rebase\&. The diffstat is also controlled by the configuration option rebase\&.stat\&. .RE .PP \-n, \-\-no\-stat .RS 4 Do not show a diffstat as part of the rebase process\&. .RE .PP \-\-no\-verify .RS 4 This option bypasses the pre\-rebase hook\&. See also \fBgithooks\fR(5)\&. .RE .PP \-\-verify .RS 4 Allows the pre\-rebase hook to run, which is the default\&. This option can be used to override \fB\-\-no\-verify\fR\&. See also \fBgithooks\fR(5)\&. .RE .PP \-C .RS 4 Ensure at least \fB\fR lines of surrounding context match before and after each change\&. When fewer lines of surrounding context exist they all must match\&. By default no context is ever ignored\&. Implies \fB\-\-apply\fR\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-no\-ff, \-\-force\-rebase, \-f .RS 4 Individually replay all rebased commits instead of fast\-forwarding over the unchanged ones\&. This ensures that the entire history of the rebased branch is composed of new commits\&. .sp You may find this helpful after reverting a topic branch merge, as this option recreates the topic branch with fresh commits so it can be remerged successfully without needing to "revert the reversion" (see the \m[blue]\fBrevert\-a\-faulty\-merge How\-To\fR\m[]\&\s-2\u[1]\d\s+2 for details)\&. .RE .PP \-\-fork\-point, \-\-no\-fork\-point .RS 4 Use reflog to find a better common ancestor between \fB\fR and \fB\fR when calculating which commits have been introduced by \fB\fR\&. .sp When \fB\-\-fork\-point\fR is active, \fIfork_point\fR will be used instead of \fB\fR to calculate the set of commits to rebase, where \fIfork_point\fR is the result of \fBgit merge\-base \-\-fork\-point \fR command (see \fBgit-merge-base\fR(1))\&. If \fIfork_point\fR ends up being empty, the \fB\fR will be used as a fallback\&. .sp If \fB\fR or \fB\-\-keep\-base\fR is given on the command line, then the default is \fB\-\-no\-fork\-point\fR, otherwise the default is \fB\-\-fork\-point\fR\&. See also \fBrebase\&.forkpoint\fR in \fBgit-config\fR(1)\&. .sp If your branch was based on \fB\fR but \fB\fR was rewound and your branch contains commits which were dropped, this option can be used with \fB\-\-keep\-base\fR in order to drop those commits from your branch\&. .sp See also INCOMPATIBLE OPTIONS below\&. .RE .PP \-\-ignore\-whitespace .RS 4 Ignore whitespace differences when trying to reconcile differences\&. Currently, each backend implements an approximation of this behavior: .PP apply backend .RS 4 When applying a patch, ignore changes in whitespace in context lines\&. Unfortunately, this means that if the "old" lines being replaced by the patch differ only in whitespace from the existing file, you will get a merge conflict instead of a successful patch application\&. .RE .PP merge backend .RS 4 Treat lines with only whitespace changes as unchanged when merging\&. Unfortunately, this means that any patch hunks that were intended to modify whitespace and nothing else will be dropped, even if the other side had no changes that conflicted\&. .RE .RE .PP \-\-whitespace=
