试试这个。。。

git fetch origin
git branch -a

remoteshow显示远程上的所有分支，包括那些本地未跟踪的分支，甚至那些尚未提取的分支。

git remote show <remote-name>

它还尝试显示分支相对于本地存储库的状态：

> git remote show origin
* remote origin
  Fetch URL: C:/git/.\remote_repo.git
  Push  URL: C:/git/.\remote_repo.git
  HEAD branch: master
  Remote branches:
    branch_that_is_not_even_fetched new (next fetch will store in remotes/origin)
    branch_that_is_not_tracked      tracked
    branch_that_is_tracked          tracked
    master                          tracked
  Local branches configured for 'git pull':
    branch_that_is_tracked merges with remote branch_that_is_tracked
    master                 merges with remote master
  Local refs configured for 'git push':
    branch_that_is_tracked pushes to branch_that_is_tracked (fast-forwardable)
    master                 pushes to master                 (up to date)

确保列出的远程源确实是所需的存储库，而不是较旧的克隆。

试试这个。。。

git fetch origin
git branch -a

为了得到我想要的东西，我最后做了一个乱七八糟的外壳管道。我刚刚合并了源远程的分支：

git branch -r --all --merged \
    | tail -n +2 \
    | grep -P '^  remotes/origin/(?!HEAD)' \
    | perl -p -e 's/^  remotes\/origin\///g;s/master\n//g'

只需运行git fetch命令。它会将所有远程分支拉到本地存储库中，然后执行git branch-a以列出所有分支。
