代码管理（五）git 删除分支
1.删除远程分支在远程下面，选择需要删除的分支，右击，选择删除
2.删除不存在远程对应分支的本地分支
在远程上建立了一个分支feature，后来leader觉得不合理，就把远程feature分支删除，并又建立了一个feature分支，这导致我在sourceTree上无法pull到最新的版本。
也假设出现这样的情况：
[*]我创建了本地分支b1并pull到远程分支 origin/b1；
[*]其他人在本地使用fetch或pull创建了本地的b1分支；
[*]我删除了 origin/b1 远程分支；
[*]其他人再次执行fetch或者pull并不会删除这个他们本地的 b1 分支，运行 git branch -a 也不能看出这个branch被删除了，如何处理？
# git remote show origin
* remote origin
Fetch URL: git@hdt.gitlab.com:engine/H2.git
PushURL: git@hdt.gitlab.com:engine/H2.git
HEAD branch: master
Remote branches:
H2-Doc tracked
develop tracked
feature/test new (next fetch will store in remotes/origin)
feature/testpush new (next fetch will store in remotes/origin)
feature_ai tracked
feature_lyp tracked
master tracked
refs/remotes/origin/13123123 stale (use 'git remote prune' to remove)
refs/remotes/origin/LogModModify stale (use 'git remote prune' to remove)
refs/remotes/origin/RequestModVideo stale (use 'git remote prune' to remove)
refs/remotes/origin/feature stale (use 'git remote prune' to remove)
refs/remotes/origin/test-1111 stale (use 'git remote prune' to remove)
refs/remotes/origin/test/test stale (use 'git remote prune' to remove)
video tracked
Local branches configured for 'git pull':
develop merges with remote develop
mastermerges with remote master
Local refs configured for 'git push':
develop pushes to develop (local out of date)
masterpushes to master(up to date)
这时候能够看到feature是stale的，使用git remote prune origin 可以将其从本地版本库中去除。
# git remote prune origin
Pruning origin
URL: git@hdt.gitlab.com:engine/H2.git
* origin/13123123
* origin/LogModModify
* origin/RequestModVideo
* origin/feature
* origin/test-1111
* origin/test/test
更简单的方法是使用这个命令，它在fetch之后删除掉没有与远程分支对应的本地分支：
git fetch -p
查看全部分支
# git branch -a
* develop
master
remotes/origin/H2-Doc
remotes/origin/HEAD -> origin/master
remotes/origin/develop
remotes/origin/feature_ai
remotes/origin/feature_lyp
remotes/origin/master
remotes/origin/video
可以看到feature分支已经被删除掉了
