远程分支的删除与同步

删除远程分支命令：

1	$ git push origin :br03

或者：

1	$ git push origin --delete br03

另外一个用户使用git fetch并不能同步获取到br03分支被删除。

1	$ git fetch

此命令没有更新的显示，说明并没有删除的信息。
但执行git pull时，报错。

1 2 3

$ git pull Your configuration specifies to merge with the ref 'br03' from the remote, but no such ref was fetched.

这确定是执行git fetch时，报错。

1 2 3

$ git fetch origin br03 fatal: Couldn't find remote ref br03 fatal: The remote end hung up unexpectedly

但检查分支时，发现origin/br03还存在。

1 2 3 4 5 6 7 8

$ git br -a br01 br02 * br03 master remotes/origin/br01-remote remotes/origin/br03 remotes/origin/master

这说明，remotes/origin/*这些远程跟踪分支，仅仅是远程分支的一个缓存，而且，不能经过git fetch命令获取到分支删除的更新。

执行命令

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

$ git remote show origin * remote origin Fetch URL: git@github0123:jeremy0123/fetch.git Push URL: git@github0123:jeremy0123/fetch.git HEAD branch: master Remote branches: br01-remote tracked br02 tracked br03-remote tracked master tracked refs/remotes/origin/br03 stale (use 'git remote prune' to remove) Local branches configured for 'git pull': br01 merges with remote br01-remote br03 merges with remote br03 master merges with remote master Local refs configured for 'git push': br02 pushes to br02 (up to date) master pushes to master (local out of date)

发现refs/remotes/origin/br03状态是stale(陈旧的)，而且后面有命令提示。

1 2 3 4

$ git remote prune origin Pruning origin URL: git@github0123:jeremy0123/fetch.git * [pruned] origin/br03

或者执行

1 2 3 4 5 6 7

$ git fetch -p remote: Counting objects: 5, done. remote: Total 3 (delta 0), reused 0 (delta 0) Unpacking objects: 100% (3/3), done. From git@github0123:jeremy0123/fetch.git 04a6837..d49d143 master -> origin/master x [deleted] (none) -> origin/br03

在执行fetch以后，删除远程不存在的远程跟踪分支。
