  问题背景

  我有一个Gitee上的仓库，但是偶然间错误的commit了一些内容，虽然我最后又更新了一版，但是之前的commit内容却还在git存储库中保存着记录，洁癖有些受不了，就google了下，找到了不错的方法。

  解决策略

  参考了这条回答：https://stackoverflow.com/a/13102849

  The only solution that works for me (and keeps submodules working) is

git checkout --orphan newBranch
git add -A  # Add all files and commit them
git commit
git branch -D master  # Deletes the master branch
git branch -m master  # Rename the current branch to master
git push -f origin master  # Force push master branch to github
git gc --aggressive --prune=all # remove the old files

Deleting .git/ always causes huge issues when I have submodules. Using git rebase --root would somehow cause conflicts for me (and take long since I had a lot of history).

关于最后一点，评论区里有回答到：

Git will keep the old files around for a while, to get rid of them run git gc --aggressive --prune=all .

需要注意

这里的 git add -A 的理解可以看这里https://www.cnblogs.com/e0yu/p/8608674.html，看上去在2.x版本中，与 git add . 无异。
