Github - 如何恢复某人提交？

Question

Someone pushed 3 commits which I want to delete, but I mean that I don't want to see them in commit history on Github, because their have wrong name. How to achieve that ?

Answer 1

That depends on what's the current status of your repository.

If those are the last three commits and you really "don't want to see them", you could reset to the commit that is located just before those three:

git reset --hard HEAD~3

And then push using --force .

In general, if you want to revert a commit, you should use git revert . For example:

git revert HEAD~<2>..HEAD

That would create a commit that removes the changes from the last three commits.

Answer 2

Assuming the three commits are the three most recent commits, the first thing that will be helpful is the sum of the parent commit that you want to revert to. For example: 6b1d1ca . You can find this on the right column of your commit history in GitHub.

Next, you want to reset your git tree to that commit using

git reset --hard 6b1d1ca

Since you are removing commits from your history, you will need to force the push to GitHub, which can be done by appending the option --force .

git push --force

Be careful using the --force option, if you have pushed commits since as they will certainly be overwritten.

Answer 3

You can the rebase command to delete or change commits messages.

• Type git rebase -i HEAD~4 . The -i option does an interactive rebasing .

• Your text editor will open with the last 4 commits listed. Each commit will have the word pick before it.

  • Delete the lines for the commits you want to delete. That will tell rebase that you don't want to keep those commits in history.

  • Save the file and close it.

• Now git should do a "rebase" of your history according to the options you chose in the file that opened, that is delete the commits you didn't want.

If you want to change the commits messages, change the pick to reword before each commit you want to edit and save the file.
