| after plenty of "a"s and "b"s, by rearranging and editing | |
| commits, and squashing multiple commits into one.</p></div> | |
| <div class="paragraph"><p>Start it with the last commit you want to retain as-is:</p></div> | |

| </div></div> | |
| <div class="paragraph"><p>An editor will be fired up with all the commits in your current branch | |
| (ignoring merge commits), which come after the given commit. You can | |
| reorder the commits in this list to your heart’s content, and you can | |
| remove them. The list looks more or less like this:</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |
| <pre><code>pick deadbee The oneline of this commit | |
| pick fa1afe1 The oneline of the next commit | |
| ...</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>The oneline descriptions are purely for your pleasure; <em>git rebase</em> will | |
| not look at them but at the commit names ("deadbee" and "fa1afe1" in this | |
| example), so do not delete or edit the names.</p></div> | |
| <div class="paragraph"><p>By replacing the command "pick" with the command "edit", you can tell | |
| <em>git rebase</em> to stop after applying that commit, so that you can edit | |
| the files and/or the commit message, amend the commit, and continue | |
| rebasing.</p></div> | |
| <div class="paragraph"><p>If you just want to edit the commit message for a commit, replace the | |
| command "pick" with the command "reword".</p></div> | |
| <div class="paragraph"><p>If you want to fold two or more commits into one, replace the command | |
| "pick" for the second and subsequent commits with "squash" or "fixup". | |
| If the commits had different authors, the folded commit will be | |
| attributed to the author of the first commit. The suggested commit | |
| message for the folded commit is the concatenation of the commit | |
| messages of the first commit and of those with the "squash" command, | |
| but omits the commit messages of commits with the "fixup" command.</p></div> | |
| <div class="paragraph"><p><em>git rebase</em> will stop when "pick" has been replaced with "edit" or | |
| when a command fails due to merge errors. When you are done editing | |
| and/or resolving conflicts you can continue with <code>git rebase --continue</code>.</p></div> | |
| <div class="paragraph"><p>For example, if you want to reorder the last 5 commits, such that what | |
| was HEAD~4 becomes the new HEAD. To achieve that, you would call | |
| <em>git rebase</em> like this:</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |
| <pre><code>$ git rebase -i HEAD~5</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>And move the first patch to the end of the list.</p></div> | |
| <div class="paragraph"><p>You might want to preserve merges, if you have a history like this:</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |
| <pre><code> X | |
| \ | |
| A---M---B | |
| / | |
| ---o---O---P---Q</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>Suppose you want to rebase the side branch starting at "A" to "Q". Make | |
| sure that the current HEAD is "B", and call</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |
| <pre><code>$ git rebase -i -p --onto Q O</code></pre> | |
| </div></div> | |
| <div class="paragraph"><p>Reordering and editing commits usually creates untested intermediate | |
| steps. You may want to check that your history editing did not break | |
| anything by running a test, or at least recompiling at intermediate | |
| points in history by using the "exec" command (shortcut "x"). You may | |
| do so by creating a todo list like this one:</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |
| <pre><code>pick deadbee Implement feature XXX | |
| fixup f1a5c00 Fix to feature XXX | |

| edit deadbab The oneline of the commit after | |
| exec cd subdir; make test | |
| ...</code></pre> | |

| <div class="paragraph"><p>The interactive rebase will stop when a command fails (i.e. exits with | |
| non-0 status) to give you an opportunity to fix the problem. You can | |
| continue with <code>git rebase --continue</code>.</p></div> | |
| <div class="paragraph"><p>The "exec" command launches the command in a shell (the one specified | |
| in <code>$SHELL</code>, or the default shell if <code>$SHELL</code> is not set), so you can | |
| use shell features (like "cd", ">", ";" …). The command is run from | |
| the root of the working tree.</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |

| <h2 id="_splitting_commits">SPLITTING COMMITS</h2> | |
| <div class="sectionbody"> | |
| <div class="paragraph"><p>In interactive mode, you can mark commits with the action "edit". However, | |
| this does not necessarily mean that <em>git rebase</em> 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:</p></div> | |
| <div class="ulist"><ul> | |
| <li> | |
| <p> | |
| Start an interactive rebase with <code>git rebase -i <commit>^</code>, where | |
| <commit> is the commit you want to split. In fact, any commit range | |
| will do, as long as it contains that commit. | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| Mark the commit you want to split with the action "edit". | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| When it comes to editing that commit, execute <code>git reset HEAD^</code>. The | |
| effect is that the HEAD is rewound by one, and the index follows suit. | |
| However, the working tree stays the same. | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| Now add the changes to the index that you want to have in the first | |
| commit. You can use <code>git add</code> (possibly interactively) or | |
| <em>git gui</em> (or both) to do that. | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| Commit the now-current index with whatever commit message is appropriate | |
| now. | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| Repeat the last two steps until your working tree is clean. | |
| </p> | |
| </li> | |
| <li> | |
| <p> | |
| Continue the rebase with <code>git rebase --continue</code>. | |
| </p> | |
| </li> | |
| </ul></div> | |
| <div class="paragraph"><p>If you are not absolutely sure that the intermediate revisions are | |
| consistent (they compile, pass the testsuite, etc.) you should use | |
| <em>git stash</em> to stash away the not-yet-committed changes | |
| after each commit, test, and amend the commit if fixes are necessary.</p></div> | |

| <div class="sectionbody"> | |
| <div class="paragraph"><p>Rebasing (or any other form of rewriting) a branch that others have | |
| based work on is a bad idea: anyone downstream of it is forced to | |
| manually fix their history. This section explains how to do the fix | |
| from the downstream’s point of view. The real fix, however, would be | |
| to avoid rebasing the upstream in the first place.</p></div> | |
| <div class="paragraph"><p>To illustrate, suppose you are in a situation where someone develops a | |
| <em>subsystem</em> branch, and you are working on a <em>topic</em> that is dependent | |
| on this <em>subsystem</em>. You might end up with a history like the | |
| following:</p></div> | |
| <div class="listingblock"> | |
| <div class="content"> | |

| </div></div> | |
| <div class="paragraph"><p>If you now continue development as usual, and eventually merge <em>topic</em> | |

| </div></div> | |
| <div class="paragraph"><p>Such duplicates are generally frowned upon because they clutter up | |
| history, making it harder to follow. To clean things up, you need to | |
| transplant the commits on <em>topic</em> to the new <em>subsystem</em> tip, i.e., | |
| rebase <em>topic</em>. This becomes a ripple effect: anyone downstream from | |
| <em>topic</em> is forced to rebase too, and so on!</p></div> | |

| <li> | |
| <p> | |
