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())

要删除已合并到主分支的本地分支，我使用以下别名（git-config-e--global）：

cleanup = "!git branch --merged master | grep -v '^*\\|master' | xargs -n 1 git branch -D"

我使用gitbranch-D来避免错误：分支“somebranch”未完全合并。消息，而我的当前签出与主分支不同。

注意：如果您的工作流可能将master和dev作为祖先，则可以添加其他分支以排除它们。通常我从“sprint-start”标签分支出来，master、dev和qa都不是祖先。

首先，列出在远程中合并的本地跟踪分支（考虑使用-r标志列出所有远程跟踪分支）。

git branch --merged

您可能会看到一些不想删除的分支。我们可以添加一些参数来跳过我们不想删除的重要分支，比如master或develop。下面的命令将跳过master分支和其中包含dev的任何内容。

git branch --merged| egrep -v "(^\*|master|main|dev)"

如果要跳过，可以将其添加到egrep命令中，如下所示。不会删除分支skip_branch_name。

git branch --merged| egrep -v "(^\*|master|main|dev|skip_branch_name)"

要删除已合并到当前签出分支的所有本地分支，请执行以下操作：

git branch --merged | egrep -v "(^\*|master|main|dev)" | xargs git branch -d

您可以看到master和dev被排除在外，以防它们是祖先。

您可以通过以下方式删除合并的本地分支：

git branch -d branchname

如果未合并，请使用：

git branch -D branchname

要从远程使用中删除它，请执行以下操作：

git push --delete origin branchname

git push origin :branchname    # for really old git

从远程删除分支后，可以通过以下方式进行修剪以消除远程跟踪分支：

git remote prune origin

或者如另一个答案所示，通过以下方式修剪单独的远程跟踪分支：

git branch -dr branchname

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。

这是一篇有助于理解这些命令的文章：Steven Harman的Git Clean:Delete Already Merged Branches。

我最喜欢的简单脚本：

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

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__"

  -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
