how to remove a file from a git commit that has been pushed
提问by ianus
I mistakenly used git commit -a and added more files than I wanted to in a commit. There was another modified file that I wanted to add as a separate commit included in this commit. How do I go back ( without losing the modifications to the files ) and then commit them all again separately.
我错误地使用了 git commit -a 并在提交中添加了比我想要的更多的文件。我想添加另一个修改过的文件作为此提交中包含的单独提交。我如何返回（不丢失对文件的修改）然后分别再次提交它们。
I've also pushed this to a remote origin ( though I know for a fact that no one has pulled anything since I pushed).
我也把它推到了一个远程源（尽管我知道自从我推以来没有人拉过任何东西）。
Many Thanks!
非常感谢！

Warning, this will overwrite the changes remotely. If anyone has taken down the current commit and worked on top of it, bad things could happen.
警告，这将远程覆盖更改。如果有人删除了当前的提交并在其之上工作，那么可能会发生不好的事情。
# Reset last commit, but keep changes staged
$ git reset --soft HEAD^1
# Unstage unwanted file(s) and recommit
$ git reset HEAD path/to/file
$ git commit
# Push the new commit with force to overwrite changes
$ git push origin -f

You can just remove these files locally and push a new commit.
您可以在本地删除这些文件并推送新的提交。
If you like to excude these files in future you can add it to .gitignore file
如果您以后想排除这些文件，可以将其添加到 .gitignore 文件中

I would immediately push the previous commit to the remote, run git reset HEAD~to put your workspace to a dirty state you were in, and then reprocess your adding, committing, and pushing.
我会立即将之前的提交推送到远程，运行git reset HEAD~以将您的工作区置于您所处的脏状态，然后重新处理您的添加、提交和推送。

If you pushed it to a separate branch (not the master), you can delete the whole branch from the remote.
如果你把它推送到一个单独的分支（不是主分支），你可以从远程删除整个分支。
After that, you can revert the commit using
之后，您可以使用还原提交
git reset --soft HEAD~1
Then you can start committing and pushing everything again.
然后你可以开始提交并再次推送所有内容。
