删除本地分支
git branch -D test –没合并也删除
git branch -d test — 没合并删除不了

删除远程分支
git push origin :feature/ttkh

查看本地分支：git branch
查看远程分支：git branch -r
查看所有分支：git branch -a

切换远程分支：git checkout -b myRelease origin/Release

git remote add origin https://github.com/wu347771769/learngit.git

把某历史版本打出分支
git checkout -b xxx/xxx 5f4648474fb38c75b69dce0db9c4d4ec1b1e6b74

合并到master分支：
git checkout master
git merge issue1234

把本地分支推送到远程分支
新建远程分支前端 CSS.md
git push origin hotfix/liyan-190905:hotfix/liyan-190905

远程已有remote_branch分支但未关联本地分支local_branch且本地已经切换到local_branch
git push -u origin/remote_branch

远程已有remote_branch分支并且已经关联本地分支local_branch且本地已经切换到local_branch
