git revert (version number)

仅有的幸福 · Answer

You won’t lose it by doing this, we all do this..
git reset --hard command rolls back to the version number modified by A
git pull --rebase origin branch number Pull down the code of B to see if there is any conflict , git push after conflict resolution

git reset --soft HEAD@{id}, this will withdraw the submission, but the modifications in the workspace will not disappear, then correct the wrong modifications, submit and push to the remote end

In this case, I usually check the log directly and restore file A to ensure that file B is complete

Don’t use git reset，如果有人已经 pull 了这些 commit，会很麻烦
这种情况下应该用 git revert on an already submitted commit on the public branch, it will generate a separate commit

git rebase -i HEAD^^^
用默认编辑器打开一个文档，修个A那次提交前面改成drop或简写为d Save.
The submission will be automatically discarded (if there is a conflict, you have to resolve the conflict yourself)

git log View the commitId of A B before A
git reset --hard A's previous commitId
git cherry-pick B’s commitId

This function is called the checkout function, and you can get the modifications submitted at a certain time
