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

编写一个脚本，Git将检查所有已合并到master的分支。

然后做git结账大师。

最后，删除合并的分支。

for k in $(git branch -ra --merged | egrep -v "(^\*|master)"); do
  branchnew=$(echo $k | sed -e "s/origin\///" | sed -e "s/remotes\///")
  echo branch-name: $branchnew
  git checkout $branchnew
done

git checkout master

for k in $(git branch -ra --merged | egrep -v "(^\*|master)"); do
  branchnew=$(echo $k | sed -e "s/origin\///" | sed -e "s/remotes\///")
  echo branch-name: $branchnew
  git push origin --delete $branchnew
done

基于这些答案，我也制作了自己的Bash脚本来实现这一点！

它使用gitbranch--merged和gitbranch-d删除已合并的分支，并在删除之前提示您输入每个分支。

merged_branches () {
    local current_branch=$(git rev-parse --abbrev-ref HEAD)
    for branch in $(git branch --merged | cut -c3-)
      do
        echo "Branch $branch is already merged into $current_branch."
        echo "Would you like to delete it? [Y]es/[N]o "
        read REPLY
        if [[ $REPLY =~ ^[Yy] ]]; then
            git branch -d $branch
        fi
    done
}

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

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()}

只是将Adam的答案稍微扩展一点：

通过运行Git-config-e--global将其添加到Git配置中

[alias]
    cleanup = "!git branch --merged | grep  -v '\\*\\|master\\|develop' | xargs -n 1 -r git branch -d"

然后，您可以通过简单的git清理来删除所有本地合并分支。
