如何修剪远程不存在的本地跟踪分支 [英] How to prune local tracking branches that do not exist on remote anymore

问题描述

使用 git remote prune origin 我可以删除远程没有的本地分支。

但我想删除那些从这些远程分支创建的本地分支（检查它们是否合并会很好）。

我该怎么做？

解决方案

修剪完成后，您可以使用 git branch -r 。可以使用 git branch -vv 检索具有远程跟踪分支的分支机构列表。因此，使用这两个列表，您可以找到不在远程列表中的远程跟踪分支。

这一行应该做到这一点（需要 bash 或 zsh ，将不能用于标准的Bourne shell）：

git branch -r | awk'{print $ 1}'| egrep -v -f / dev / fd / 0 <（git branch -vv | grep origin）| awk'{print $ 1}'| xargs git branch -d

该字符串获取远程分支的列表并将它传递给 egrep 通过标准输入。并过滤具有远程跟踪分支的分支（使用 git branch -vv 并过滤那些具有 origin 的分支）然后获取该输出的第一列，这将是分支名称。最后将所有分支名称传递到delete分支命令中。

因为它使用 -d 选项，不会删除当您运行此命令时尚未合并到您所在分支中的分支。

还要记住，您需要运行 git fetch --prune first ，否则 git branch -r 仍会看到远程分支。 p>

With git remote prune origin I can remove the local branches that are not any more on the remote.

But I want to remove also those local branches that were created from those remote branches (a check if they are unmerged would be nice).

How can I do this?

解决方案

After pruning, you can get the list of remote branches with git branch -r. The list of branches with their remote tracking branch can be retrieved with git branch -vv. So using these two lists you can find the remote tracking branches that are not in the list of remotes.

This line should do the trick (requires bash or zsh, won't work with standard Bourne shell):

git branch -r | awk '{print $1}' | egrep -v -f /dev/fd/0 <(git branch -vv | grep origin) | awk '{print $1}' | xargs git branch -d

This string gets the list of remote branches and passes it into egrep through the standard input. And filters the branches that have a remote tracking branch (using git branch -vv and filtering for those that have origin) then getting the first column of that output which will be the branch name. Finally passing all the branch names into the delete branch command.

Since it is using the -d option, it will not delete branches that have not been merged into the branch that you are on when you run this command.

Also remember that you'll need to run git fetch --prune first, otherwise git branch -r will still see the remote branches.
