下面是如何使用Magit。

比如提交ed417ae是你想要修改的;它包含两个不相关的更改，并隐藏在一个或多个提交之下。点击ll显示日志，并导航到ed417ae:

然后按r打开rebase弹出框

m用来修改提交点。

注意@现在在你想要拆分的提交上——这意味着HEAD现在在提交上:

我们想要移动HEAD到父节点，所以导航到父节点(47e18b3)并点击x (magit-reset-quick，如果你使用evil-magit，则绑定到o)，然后进入说“是的，我的意思是提交点”。您的日志现在应该如下所示:

现在，点击q进入常规的Magit状态，然后使用常规的unstage u命令取消第一次提交中没有进入的阶段，像往常一样提交c，然后stage并提交第二次提交的内容，完成后:点击r打开rebase弹出框

还有一个r继续，就完成了!Ll现在显示:

拆分一个<commit>的提交，并在此之前添加新的提交，并保存<commit>的作者日期，-步骤如下:

Edit the commit before <commit> git rebase -i <commit>^^ NB: perhaps it will be also needed to edit <commit> as well. Cherry pick <commit> into the index git cherry-pick -n <commit> Interactively reset unneeded changes from the index and reset the working tree git reset -p && git checkout-index -f -a As alternative, just stash unneeded changes interactively: git stash push -p -m "tmp other changes" Make other changes (if any) and create the new commit git commit -m "upd something" . Optionally, repeat the items 2-4 to add more intermediate commits. Continue rebasing git rebase --continue

如果你还没有推送，请使用git rebase。更好的是，使用git rebase -i来交互地移动提交。您可以将有问题的提交移到前面，然后根据需要将其拆分并将补丁移到后面(如果需要的话)。

如果你只想从一个文件中提取内容，还有一个更快的版本。它更快，因为交互式rebase实际上不再是交互式的(当然，如果您想从上次提交中提取，那么根本不需要rebase，那么它甚至更快)

Use your editor and delete the lines you want to extract from the_file. Close the_file. That's the only edition you need, all the rest is just git commands. Stage that deletion in the index: git add the_file Restore the lines you just deleted back into the file without affecting the index! git show HEAD:./the_file > the_file "SHA1" is the commit you want to extract the lines from: git commit -m 'fixup! SHA1' Create the second, brand new commit with the content to extract restored by step 3: git commit -m 'second and new commit' the_file Don't edit, don't stop/continue - just accept everything: git rebase --autosquash -i SHA1~1

当然，如果要提取的commit是最后一次提交，则会更快:

4. git commit -C HEAD --amend
5. git commit -m 'second and new commit' thefile
6. no rebase, nothing

如果你使用magit，那么第4步，第5步和第6步是一个动作:提交，立即修复

在rebase manpage中有一个拆分提交的指南。简要总结如下:

Perform an interactive rebase including the target commit (e.g. git rebase -i <commit-to-split>^ branch) and mark it to be edited. When the rebase reaches that commit, use git reset HEAD^ to reset to before the commit, but keep your work tree intact. Incrementally add changes and commit them, making as many commits as desired. add -p can be useful to add only some of the changes in a given file. Use commit -c ORIG_HEAD if you want to re-use the original commit message for a certain commit. If you want to test what you're committing (good idea!) use git stash to hide away the part you haven't committed (or stash --keep-index before you even commit it), test, then git stash pop to return the rest to the work tree. Keep making commits until you get all modifications committed, i.e. have a clean work tree. Run git rebase --continue to proceed applying the commits after the now-split commit.
