我使用以下Ruby脚本删除已经合并的本地和远程分支。如果我对一个有多个遥控器的存储库执行此操作，并且只想从一个遥控器中删除，那么我只需在遥控器列表中添加一个select语句，即可获得所需的遥控器。

#!/usr/bin/env ruby

current_branch = `git symbolic-ref --short HEAD`.chomp
if current_branch != "master"
  if $?.exitstatus == 0
    puts "WARNING: You are on branch #{current_branch}, NOT master."
  else
    puts "WARNING: You are not on a branch"
  end
  puts
end

puts "Fetching merged branches..."
remote_branches= `git branch -r --merged`.
  split("\n").
  map(&:strip).
  reject {|b| b =~ /\/(#{current_branch}|master)/}

local_branches= `git branch --merged`.
  gsub(/^\* /, '').
  split("\n").
  map(&:strip).
  reject {|b| b =~ /(#{current_branch}|master)/}

if remote_branches.empty? && local_branches.empty?
  puts "No existing branches have been merged into #{current_branch}."
else
  puts "This will remove the following branches:"
  puts remote_branches.join("\n")
  puts local_branches.join("\n")
  puts "Proceed?"
  if gets =~ /^y/i
    remote_branches.each do |b|
      remote, branch = b.split(/\//)
      `git push #{remote} :#{branch}`
    end

    # Remove local branches
    `git branch -d #{local_branches.join(' ')}`
  else
    puts "No branches removed."
  end
end

为了避免意外地从master以外的任何其他分支运行命令，我使用以下bash脚本。否则，从已合并非主分支的分支运行git branch--merged |grep-v“\*”|xargs-n 1 git branch-d可能会删除主分支。

#!/bin/bash

branch_name="$(git symbolic-ref HEAD 2>/dev/null)" ||
branch_name="(unnamed branch)"     # detached HEAD
branch_name=${branch_name##refs/heads/}

if [[ $branch_name == 'master' ]]; then
   read -r -p "Are you sure? [y/N] " response
   if [[ $response =~ ^([yY][eE][sS]|[yY])$ ]]; then
       git branch --merged | grep -v "\*" | xargs -n 1 git branch -d
   fi
else
   echo "Refusing to delete branches that are not merged into '$branch_name'. Checkout master first."
fi

公认的解决方案很好，但有一个问题，它还删除了尚未合并到远程的本地分支。

如果你查看的输出，你会看到

$ git branch --merged master -v
  api_doc                  3a05427 [gone] Start of describing the Java API
  bla                      52e080a Update wording.
  branch-1.0               32f1a72 [maven-release-plugin] prepare release 1.0.1
  initial_proposal         6e59fb0 [gone] Original proposal, converted to AsciiDoc.
  issue_248                be2ba3c Skip unit-for-type checking. This needs more work. (#254)
  master                   be2ba3c Skip unit-for-type checking. This needs more work. (#254)

分支bla和issue_248是将被默默删除的本地分支。

但您也可以看到单词[gone]，它表示已被推到远程（现在已不存在）的分支，因此表示可以删除分支。

因此，原始答案可以更改为（拆分为多行以缩短行长度）

git branch --merged master -v | \
     grep  "\\[gone\\]" | \
     sed -e 's/^..//' -e 's/\S* .*//' | \
      xargs git branch -d

以保护尚未合并的分支。此外，也不需要为master提供保护，因为它在源位置有一个远程，不会显示为已删除。

您可以将提交添加到--merged选项。这样，您可以确保只删除合并到原始/主文件中的分支

以下命令将从原点删除合并的分支。

git branch -r --merged origin/master | grep -v "^.*master" | sed s:origin/:: |xargs -n 1 git push origin --delete 

您可以测试将删除哪些分支来替换git推送原点--delete with echo

git branch -r --merged origin/master | grep -v "^.*master" | sed s:origin/:: |xargs -n 1 echo

您需要从这些命令中排除master、main和develop分支。

本地git清除：

git branch --merged | grep -v '\*\|master\|main\|develop' | xargs -n 1 git branch -d

远程清零：

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

同步远程分支的本地注册表：

git fetch -p

Git Sweep在这方面做得很好。
