Adam更新答案的别名版本：

[alias]
    branch-cleanup = "!git branch --merged | egrep -v \"(^\\*|master|dev)\" | xargs git branch -d #"

此外，请参阅此答案以获得有关转义复杂别名的实用提示。

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。

您可以使用git del br工具。

git-del-br -a

您可以使用pip安装它

pip install git-del-br

P.S：我是这个工具的作者。欢迎提出任何建议/反馈。

我最喜欢的简单脚本：

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

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。

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
}
