库布恩的回答没有删除分支名称中包含单词master的分支。以下内容改进了他的回答：

git branch -r --merged | grep -v "origin/master$" | sed 's/\s*origin\///' | xargs -n 1 git push --delete origin

当然，它不会删除“master”分支本身：）

如果您想删除已合并到当前所在分支的所有本地分支，那么我根据前面的回答提出了一个安全的命令：

git branch --merged | grep -v \* | grep -v '^\s*master$' | xargs -t -n 1 git branch -d

此命令不会影响当前分支或主分支。它还将使用xargs的-t标志告诉您它在做什么。

对于那些使用Windows并喜欢PowerShell脚本的人，这里有一个删除本地合并分支的脚本：

function Remove-MergedBranches
{
  git branch --merged |
    ForEach-Object { $_.Trim() } |
    Where-Object { $_ -NotMatch "^\*" } |
    Where-Object { -not ( $_ -Like "*master" -or $_ -Like "*main" ) } |
    ForEach-Object { git branch -d $_ }
}

或者简称：

git branch --merged | %{$_.trim()}  | ?{$_ -notmatch 'dev' -and $_ -notmatch 'master' -and $_ -notmatch 'main'} | %{git branch -d $_.trim()}

我最喜欢的简单脚本：

git branch --merged | grep -E -v "(master|main|develop|other)" | xargs git branch -d

请尝试以下命令：

git branch -d $(git branch --merged | grep -vw $(git rev-parse --abbrev-ref HEAD))

通过使用gitrevparse，将获取当前分支名称以排除它。如果出现错误，则意味着没有要删除的本地分支。

要对远程分支执行相同操作（使用远程名称更改源），请尝试：

git push origin -vd $(git branch -r --merged | grep -vw $(git rev-parse --abbrev-ref HEAD) | cut -d/ -f2)

如果您有多个遥控器，请在剪切之前添加grep-origin |，以仅过滤源。

如果上述命令失败，请尝试先删除合并的远程跟踪分支：

git branch -rd $(git branch -r --merged | grep -vw $(git rev-parse --abbrev-ref HEAD))

然后git再次获取远程，并再次使用前面的gitpush-vd命令。

如果您经常使用它，请考虑将别名添加到~/.gitconfig文件中。

如果您错误地删除了一些分支，请使用gitreflog查找丢失的提交。

我的Bash脚本贡献大致基于mmrobin的答案。

它需要一些有用的参数来指定include和exclude，或者只检查/删除本地或远程分支，而不是两者。

#!/bin/bash

# exclude branches regex, configure as "(branch1|branch2|etc)$"

  -e) shift; excludes="$1" ;;
  --no-local) local=0 ;;
  --no-remote) remote=0 ;;
  --all) merged= ;;
  *) echo "Unknown argument $1"; exit 1 ;;
  esac
  shift   # next option
done
