使用 git branch -a 命令可以查看所有本地分支和远程分支（git branch -r 可以只查看远程分支）
发现很多在远程仓库已经删除的分支在本地依然可以看到。
# git branch -a
2-android-tableview-resize
20180131hotfix
master
release0308_licaiHome_v52
release0322
* release20180412_from0326
remotes/origin/2-android-tableview-resize
remotes/origin/20180131hotfix
remotes/origin/HEAD -> origin/master
remotes/origin/dev
remotes/origin/dev_cache_renxj
使用命令 git remote show origin，可以查看remote地址，远程分支，还有本地分支与之相对应关系等信息。
# git remote show origin
* remote origin
Fetch URL: git@*********
Push URL: git@**********
HEAD branch: master
Remote branches:
2-android-tableview-resize tracked
20180131hotfix tracked
master tracked
mergeFrom0808AndDev tracked
refs/remotes/origin/3IN1 stale (use 'git remote prune' to remove)
refs/remotes/origin/3IN1_v052 stale (use 'git remote prune' to remove)
refs/remotes/origin/dev20171214 stale (use 'git remote prune' to remove)
......
release1228 tracked
release20180130 tracked
Local branches configured for 'git pull':
2-android-tableview-resize merges with remote 2-android-tableview-resize
20180131hotfix merges with remote 20180131hotfix
3IN1 merges with remote 3IN1
dev merges with remote dev
dev20171214 merges with remote dev20171214
......
Local refs configured for 'git push':
2-android-tableview-resize pushes to 2-android-tableview-resize (up to date)
20180131hotfix pushes to 20180131hotfix (up to date)
........
此时我们可以看到那些远程仓库已经不存在的分支，根据提示，使用 git remote prune origin 命令：
git remote prune origin
Pruning origin
URL: git@**********
* [pruned] origin/3IN1
* [pruned] origin/3IN1_v052
* [pruned] origin/dev20171214
........
这样就删除了那些远程仓库不存在的分支。
