对于Windows，您可以使用以下命令安装Cygwin并删除所有远程分支：

git branch -r --merged | "C:\cygwin64\bin\grep.exe" -v master | "C:\cygwin64\bin\sed.exe" 's/origin\///' | "C:\cygwin64\bin\xargs.exe" -n 1 git push --delete origin

我一直在使用以下方法在一个cmd中删除合并的本地AND远程分支。

我的bashrc文件中有以下内容：

function rmb {
  current_branch=$(git branch --no-color 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/')
  if [ "$current_branch" != "master" ]; then
    echo "WARNING: You are on branch $current_branch, NOT master."
  fi
  echo "Fetching merged branches..."
  git remote prune origin
  remote_branches=$(git branch -r --merged | grep -v '/master$' | grep -v "/$current_branch$")
  local_branches=$(git branch --merged | grep -v 'master$' | grep -v "$current_branch$")
  if [ -z "$remote_branches" ] && [ -z "$local_branches" ]; then
    echo "No existing branches have been merged into $current_branch."
  else
    echo "This will remove the following branches:"
    if [ -n "$remote_branches" ]; then
      echo "$remote_branches"
    fi
    if [ -n "$local_branches" ]; then
      echo "$local_branches"
    fi
    read -p "Continue? (y/n): " -n 1 choice
    echo
    if [ "$choice" == "y" ] || [ "$choice" == "Y" ]; then
      # Remove remote branches
      git push origin `git branch -r --merged | grep -v '/master$' | grep -v "/$current_branch$" | sed 's/origin\//:/g' | tr -d '\n'`
      # Remove local branches
      git branch -d `git branch --merged | grep -v 'master$' | grep -v "$current_branch$" | sed 's/origin\///g' | tr -d '\n'`
    else
      echo "No branches removed."
    fi
  fi
}

这不会删除主分支，而是删除合并的本地和远程分支。一旦你在你的rc文件中有了这个，只需运行rmb，你会看到一个合并的分支列表，这些分支将被清理并要求确认操作。您可以修改代码，不要求确认，但最好保留它。

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

我使用这个：

git branch --delete $(git branch --format '%(refname:short)' --merged | grep --invert-match 'main\|master\|branch-to-skip')

它以指定的格式列出所有合并的分支，然后将该列表提供给gitbranch-delete。

要删除合并的分支，gitdelete合并的分支比shell黑客更健壮、更方便。它还检测重基合并和挤压合并。它的自述文件有更多细节。

如果您希望删除已合并的本地分支以及删除它们的远程控制器，这里是我更喜欢的一行代码：

git branch --merged | xargs -I_br -- sh -c 'git branch -d _br; git push origin --delete _br'
