把舊項(xiàng)目提交到git上，但是會(huì)有一些歷史記錄，這些歷史記錄中可能會(huì)有項(xiàng)目密碼等敏感信息。如何刪除這些歷史記錄，形成一個(gè)全新的倉庫，并且保持代碼不變呢？

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
