刪除本地分支
git branch -D分支名稱
刪除遠程分支
git push origin --delete遠程分支名稱
刪除在本地有但在遠程庫中已經不存在的分支
git remote show origin
可以查看遠程庫的一些信息，及與本地分支的信息。有時候可能遇到如下情況
$ git remote show origin
* remote origin
Fetch URL: ... .git
Push URL: ... .git
HEAD branch: master
Remote branches:
dev tracked
jqmobi tracked
master tracked
refs/remotes/origin/3.1 stale(use 'git remote prune' to remove)
refs/remotes/origin/tc stale(use 'git remote prune' to remove)
refs/remotes/origin/xhl stale(use 'git remote prune' to remove)
Local branches configured for 'git pull':
dev merges with remote dev
master merges with remote master
Local refs configured for 'git push':
dev pushes to dev (up to date)
jqmobi pushes to jqmobi(up to date)
master pushes to master(up to date)
其中3.1, tc, xhl三個分支在遠程庫已經不存在了（你之前從遠程庫拉取過，可能之后被其他人刪除了，你用 git branch -a 也是不能看出它們是否已被刪除的），這時候我們可以刪除本地庫中這些相比較遠程庫中已經不存在的分支：
$ git remote prune origin
Password for '...':
Pruning origin
URL: ... .git
*[pruned]origin/3.1
*[pruned]origin/tc
*[pruned]origin/xhl
