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()}

以下查询适用于我

for branch in  `git branch -r --merged | grep -v '\*\|master\|develop'|awk 'NR > 0 {print$1}'|awk '{gsub(/origin\//, "")}1'`;do git push origin --delete $branch; done

这将过滤grep管道中的任何给定分支。

在http克隆上运行良好，但在ssh连接上运行不太好。

Windoze友好的Python脚本（因为git sweep阻塞了Wesnoth存储库）：

#!/usr/bin/env python
# Remove merged git branches. Cross-platform way to execute:
#
#   git branch --merged | grep -v master | xargs git branch -d
#
# Requires gitapi - https://bitbucket.org/haard/gitapi
# License: Public Domain

import gitapi

repo = gitapi.Repo('.')
output = repo.git_command('branch', '--merged').strip()
for branch in output.split('\n'):
  branch = branch.strip()
  if branch.strip(' *') != 'master':
    print(repo.git_command('branch', '-d', branch).strip())

如果您使用的是HubFlow或GitFlow等分支模型，则可以使用此命令删除合并的功能分支：

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

刚刚为此创建了python脚本：

import sys
from shutil import which
import logging
from subprocess import check_output, call

logger = logging.getLogger(__name__)

if __name__ == '__main__':
    if which("git") is None:
        logger.error("git is not found!")
        sys.exit(-1)

    branches = check_output("git branch -r --merged".split()).strip().decode("utf8").splitlines()
    current = check_output("git branch --show-current".split()).strip().decode("utf8")
    blacklist = ["master", current]

    for b in branches:
        b = b.split("/")[-1]

        if b in blacklist:
            continue
        else:
            if input(f"Do you want to delete branch: '{b}' [y/n]\n").lower() == "y":
                call(f"git branch -D {b}".split())
                call(f"git push --delete origin {b}".split())

gitbranch--merged|grep-Ev'^（.master |\*）'|xargs-n 1 gitbranch-d将删除除当前签出的分支和/或主分支外的所有本地分支。
