从Git中删除旧的远程分支 [英] Remove old remote branches from Git

问题描述

当我在Git中使用bash autocompletion时，它不断向我展示我不再拥有的旧遥控器的分支。当我做一个 git branch -la 时，它会显示那些旧的远程和分支，而 git分支-l 不会。一个 ls .git / refs / remotes / 也会显示它们。但是，它们并不存在于我的 .git / config 中，当我运行 git remote show 时，它们都不显示。

那么我该如何摆脱它们呢，因为我的自动完成列表现在太长了。

我已经试过了：

  git reflog expire --expire = now  -  all 
 git gc --prune = now 
 rm .git / refs / remotes / theoldremote 
 git remote prune theoldremote 
  

我也意识到我可以重新克隆回购，但这只是作弊; - ）

此外，在V2.0.1之前，当您从git配置中移除远程设备时，远程追踪分支在某些情况下不会被删除（请参阅VonC的答案）。

删除过时的远程 - 为您的远程存储库之一追踪分支（在远程存储库中删除的分支），运行

  git remote prune<远程> 
  

引用手册页或 git remote ：
$ b

修剪

删除< name>下的所有陈旧跟踪分支。这些陈旧的分支已从$ lt; name> ;,
引用的远程存储库中移除
，但仍在远程/<名称>中本地可用。

使用--dry-run选项，报告将修剪哪些分支，但
不会实​​际修剪它们。

然而，从你的问题看来，你似乎手动删除了 .git / refs / remotes / theoldremote ，所以Git不再了解远程存储库，跟踪分支属于。这不是你应该怎么做的。

删除远程仓库的正常方法是运行

  git remote rm< remote> 
  

这将从您的 .git / config


如果您只是删除 .git / refs / remotes / 下的目录，则会删除远程跟踪分支。 code>，分支机构将保持在后面。然后您需要手动删除它们：

  git branch -rd< remote> /< branchname> 
  

您需要选项 -r 来删除远程分支。

When I use bash autocompletion in Git, it keeps showing me branches of old remotes that I don't have anymore. When I do a git branch -la it shows those old remotes and branches while a git branch -l won't. A ls .git/refs/remotes/ also shows them. However, they are not present in my .git/config and neither are they shown when I run git remote show.

So how do I get rid of them because my autocomplete list is too long right now.

I have already tried:

git reflog expire --expire=now --all
git gc --prune=now
rm .git/refs/remotes/theoldremote
git remote prune theoldremote

I'm also aware of the fact that I can just re-clone the repo but that's just cheating ;-)

解决方案

Git does not delete the (local) remote-tracking branches automatically if the branch was deleted in the remote repository. Additionally, before V2.0.1 remote-tracking branches were in some cases not deleted when you removed the remote from your git config (see VonC's answer).

To delete stale remote-tracking branches (branches that were deleted in the remote repository) for one of your remote repositories, run

git remote prune <remote>

To cite the man page or git remote:

prune

Deletes all stale tracking branches under <name>. These stale branches have already been removed from the remote repository referenced by <name>, but are still locally available in "remotes/<name>".

With --dry-run option, report what branches will be pruned, but do not actually prune them.

However, from your question it seems you manually removed .git/refs/remotes/theoldremote, so Git no longer knows about the remote repository that the remote-tracking branches belonged to. That's not how you're supposed to do it.

The normal way to remove a remote repository is to run

git remote rm <remote>

This will remove the remote from your .git/config, and will delete the remote-tracking branches.

If you just delete the directory under .git/refs/remotes/, the branches will remain behind. Then you will need to remove them manually:

git branch -rd <remote>/<branchname>

You need option -r to delete a remote branch.
