I wanted something that would purge all local branches that were tracking a remote branch, on origin, where the remote branch has been deleted (gone). I did not want to delete local branches that were never set up to track a remote branch (i.e.: my local dev branches). Also, I wanted a simple one-liner that just uses git, or other simple CLI tools, rather than writing custom scripts. I ended up using a bit of grep and awk to make this simple command, then added it as an alias in my ~/.gitconfig.

[alias]
  prune-branches = !git remote prune origin && git branch -vv | grep ': gone]' | awk '{print $1}' | xargs -r git branch -D

这是一个git配置-全局…命令可以方便地将其添加为git prune-branches:

git config --global alias.prune-branches '!git remote prune origin && git branch -vv | grep '"'"': gone]'"'"' | awk '"'"'{print $1}'"'"' | xargs -r git branch -d'

注意:对git分支使用-D标志可能非常危险。所以，在上面的config命令中，我使用-d选项来git分支而不是-d;我在实际配置中使用-D。我使用-D是因为我不想听到Git抱怨未合并的分支，我只是想让它们消失。您可能也需要这个功能。如果是这样，只需在配置命令的末尾使用-D而不是-D。

基于以上的答案，我想出了这个简单的解决方案:

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

我到达这个页面，寻求“如何删除不再有上游分支的本地签出分支”的答案。

我也不关心本地分支是否已经被合并，因为管道到git branch -d只会发出警告，而不是删除未合并的本地分支。

git branch -a | grep origin | tr -s ' ' | cut -d '/' -f3 | egrep -v -f /dev/fd/0 <(git branch -a | grep -v origin) | grep branch_prefix_that_I_care_about | xargs git branch -d

# translation
# git branch -a | grep origin | tr -s ' ' | cut -d '/' -f3
## this finds all remote branch names minus the "remote/origin/" part
#
# <(git branch -a | grep -v origin)
## this finds all local branch names and redirects it into the previous command
#
# egrep -v -f /dev/fd/0 STUFF
## this is doing some weird magic that I'm grokking as "take the set difference from whatever was piped in"
#
#
# overall translation: (STUFF TO CONSIDER) | egrep magic <(STUFF TO REMOVE FROM CONSIDERATION) | do cool things with resulting stuff

除了Schleis的答案(它工作得很完美)，它还可以集成到Visual Studio中，所以在VS中打开git repo时修剪本地分支非常简单。

您可以使用外部工具功能调用sh.exe (git bash)与特定的目录和命令。它位于工具>外部工具菜单选项中(在VS 2022 17.1.0中)。我使用的参数如下:

命令:{Path-To-Git-Installation-Location} \ bin \ sh.exe

参数:——cd=$(SolutionDir) -c "git fetch -p;Git branch -r | awk '{print $1}' | egrep -v -f /dev/ fg /0 <(Git branch -vv | grep origin) | awk '{print $1}' | xargs Git branch -d"

初始目录:$(SolutionDir)

值得注意的是，只有当你在VS中打开的解决方案在git repo目录中时，这才会起作用。

最后提醒-这可以通过Visual Studio的按键绑定用户界面在设置>通用>键盘和搜索工具进行按键绑定。ExternalCommand[n]，其中n是外部命令表中的位置，您有这个外部工具的位置(它们可以在工具>外部工具对话框中重新排序)。请看下面的截图。

键盘绑定外部工具命令

您可以使用该命令:

git branch --merged master | grep -v "\* master" | xargs -n 1 git branch -d

Git清洁:删除已经合并的分支，包括分解命令

我已经把公认的答案变成了一个健壮的脚本。您可以在我的git-extensions存储库中找到它。

$ git-rprune --help
Remove old local branches that do not exist in REMOTE any more.
With --test, only print which local branches would be deleted.
Note: To do this automatically on each fetch / pull:
    git config --global fetch.prune true
Usage: git-rprune REMOTE [-t|--test|-f|--force] [-?|-h|--help]
