git远程删除分支后，本地git branch -a 依然能看到的解决办法

http://blog.csdn.net/qq_16885135/article/details/52777871

使用 git branch -a 命令可以查http://blog.csdn.net/qq_16885135/article/details/52777871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  movtop  task_develop* weibo  remotes/origin/HEAD -> origin/task_develop  remotes/origin/develop  remotes/origin/fix_composer_repositories_type  remotes/origin/join_weixin_module  remotes/origin/master  remotes/origin/mining-backup  remotes/origin/movtop  remotes/origin/right  remotes/origin/schedule_dev  remotes/origin/stuff_web_fix  remotes/origin/task_develop  remotes/origin/task_idea  remotes/origin/task_temp  remotes/origin/task_yqj  remotes/origin/weibo  remotes/origin/weixin_temp

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: https://[e-mail]/xxx/xxx.git  Push  URL: https://[e-mail]/xxx/xxx.git  HEAD branch: task_develop  Remote branches:    master                                             tracked    mining-backup                                      tracked    refs/remotes/origin/develop                        stale (use 'git remote prune' to remove)    refs/remotes/origin/fix_composer_repositories_type stale (use 'git remote prune' to remove)    refs/remotes/origin/join_weixin_module             stale (use 'git remote prune' to remove)    refs/remotes/origin/movtop                         stale (use 'git remote prune' to remove)    refs/remotes/origin/right                          stale (use 'git remote prune' to remove)    refs/remotes/origin/schedule_dev                   stale (use 'git remote prune' to remove)    refs/remotes/origin/stuff_web_fix                  stale (use 'git remote prune' to remove)    refs/remotes/origin/task_temp                      stale (use 'git remote prune' to remove)    refs/remotes/origin/weibo                          stale (use 'git remote prune' to remove)    task_develop                                       tracked    task_idea                                          tracked    task_yqj                                           tracked    weixin_temp                                        tracked  Local branches configured for 'git pull':    movtop       merges with remote movtop    task_develop merges with remote task_develop    weibo        merges with remote weibo  Local ref configured for 'git push':    task_develop pushes to task_develop (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 originPruning originURL: https://[e-mail]/xxx/xxx.git * [pruned] origin/develop * [pruned] origin/fix_composer_repositories_type * [pruned] origin/join_weixin_module * [pruned] origin/movtop * [pruned] origin/right * [pruned] origin/schedule_dev * [pruned] origin/stuff_web_fix * [pruned] origin/task_temp * [pruned] origin/weibo
