Git清空所有commit记录方法

说明：例如将代码提交到git仓库，将一些敏感信息提交，所以需要删除提交记录以彻底清除提交信息，以得到一个干净的仓库且代码不变

1. Checkout

git checkout –-orphan latest_branch

2. Add all the files

git add -A

3. Commit the changes

git commit -am "commit message"

4. Delete the branch

git branch -D master

5. Rename the current branch to master

git branch -m master

6. Finally, force update your repository

git push -f origin master
