How to delete the last n commits on Github and locally?
提问by Ivan Fernandez
I'm trying to delete the last 2 commits from one of my GitHub repositories. I've tried as suggested here: git push -f origin HEAD^^:master. It seems that it works, as the last two commits are removed.
我正在尝试从我的 GitHub 存储库之一中删除最后 2 个提交。我已经按照这里的建议尝试过：git push -f origin HEAD^^:master。似乎它有效，因为最后两个提交被删除了。
Then I deleted them from my local repository with git rebase -i HEAD~2. I remove the lines that are related to those commits, and check with git logthat they are correctly removed.
然后我从我的本地存储库中删除了它们git rebase -i HEAD~2。我删除了与这些提交相关的行，并检查git log它们是否被正确删除。
After that, I make some changes in my local repository, make a new commit, and push to GitHub. The problem is that, in my GitHub account, I have the previous two commits that I've tried to delete.
之后，我在本地存储库中进行了一些更改，进行了新的提交，然后推送到 GitHub。问题是，在我的 GitHub 帐户中，我尝试删除了前两个提交。
I think the problem is in my local repository, because if I clone my Github repository to my local and make some changes here, when I push a new commit those old commits aren't pushed to GitHub.
我认为问题出在我的本地存储库中，因为如果我将 Github 存储库克隆到本地并在此处进行一些更改，那么当我推送新提交时，这些旧提交不会推送到 GitHub。
Any idea?
任何的想法？

To remove the last two commits locally I'd suggest using:
要在本地删除最后两个提交，我建议使用：
git reset --hard HEAD^^
Rebase is a completely different operation that won't help you here.
Rebase 是一个完全不同的操作，在这里对您没有帮助。

If you want to remove the 2 (two) last commits, there is an easy command to do that:
如果您想删除 2（两）次最后提交，有一个简单的命令可以执行此操作：
git reset --hard HEAD~2
You can change the 2for any number of last commits you want to remove.
您可以更改2要删除的任意数量的最后提交。
And to push this change to remote, you need to do a git pushwith the force(-f) parameter:
并且要将此更改推送到远程，您需要git push使用force( -f) 参数进行操作：
git push -f
However, I don't recommendto do any gitcommand with -for --hardoptions involved if there are new commitson remote (Github) afterthis commits that you want to remove. In that case, always use git revert.
但是，如果在远程（Github）上有新的提交后您要删除，我不建议执行任何涉及的git命令-f或--hard选项。在这种情况下，请始终使用.git revert

The following works for me
以下对我有用
git reset HEAD~n
It removes the last ncommits from local repo, as HEAD^removes only one. If you need to remove these changes from remote, you might need to force push as you will be behind remote.
它n从本地存储库中删除最后一个提交，因为HEAD^只删除一个。如果您需要从远程删除这些更改，您可能需要强制推送，因为您将落后于远程。
git push -f origin <branch>
