Git中没有命令会自动为您执行此操作。但是你可以编写一个脚本，使用Git命令来满足你的需要。这可以通过多种方式实现，具体取决于您使用的分支模型。

如果您需要知道分支是否已合并到master中，如果myTopicBranch已合并，则以下命令将不会产生输出（即，您可以删除它）

$ git rev-list master | grep $(git rev-parse myTopicBranch)

您可以使用Gitbranch命令解析出Bash中的所有分支，并对所有分支执行for循环。在这个循环中，您可以使用上面的命令检查是否可以删除分支。

将其添加到~/.gitconfig的[alias]部分：

sweep = !"f() { git branch --merged | egrep -v \"(^\\*|master|dev)\" || true | xargs git branch -d; }; f"

现在，您只需调用git扫描来执行所需的清理。

这也适用于删除除主分支之外的所有合并分支。

git branch --merged | grep -v '^* master$' | grep -v '^  master$' | xargs git branch -d

如果要删除合并的分支，则只需删除远程跟踪分支，除非您另有说明。

因此，要删除这些分支，您可以通过

git branch--remote--合并原始/主|egrep-v“（^\*|master|development）”|cut-b 10-|xargs git push--删除原始

这将删除除主分支和开发分支外的所有合并分支（合并到主分支）。

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())

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)$"
excludes_default="(master|next|ag/doc-updates)$"
excludes="__NOTHING__"
includes=
merged="--merged"
local=1
remote=1

  case "$1" in
  -i) shift; includes="$includes $1" ;;
  -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

if [ "$includes" == "" ]; then
  includes=".*"

  includes="($(echo $includes | sed -e 's/ /|/g'))"
