Git 清除远端已删除的分支

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。
