1.切换到新的分支
git checkout --orphan latest_branch
缓存所有文件(除了.gitignore中声名排除的)
git add -A提交跟踪过的文件(Commit the changes)
git commit -am "commit message"-
删除master分支(Delete the branch)
git branch -D master
5.重命名当前分支为master(Rename the current branch to master)git branch -m master
6.提交到远程master分支 (Finally, force update your repository)git push -f origin master
