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

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__"
includes=
merged="--merged"
local=1
remote=1

while [ $# -gt 0 ]; do
  case "$1" in
  -i) shift; includes="$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

if [ "$includes" == "" ]; then
  includes=".*"
else
  includes="($(echo $includes | sed -e 's/ /|/g'))"
fi

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 -e "Fetching branches...\n"

git remote update --prune
remote_branches=$(git branch -r $merged | grep -v "/$current_branch$" | grep -v -E "$excludes" | grep -v -E "$excludes_default" | grep -E "$includes")
local_branches=$(git branch $merged | grep -v "$current_branch$" | grep -v -E "$excludes" | grep -v -E "$excludes_default" | grep -E "$includes")
if [ -z "$remote_branches" ] && [ -z "$local_branches" ]; then
  echo "No existing branches have been merged into $current_branch."
else
  echo "This will remove the following branches:"
  if [ "$remote" == 1 -a -n "$remote_branches" ]; then
    echo "$remote_branches"
  fi
  if [ "$local" == 1 -a -n "$local_branches" ]; then
    echo "$local_branches"
  fi
  read -p "Continue? (y/n): " -n 1 choice
  echo
  if [ "$choice" == "y" ] || [ "$choice" == "Y" ]; then
    if [ "$remote" == 1 ]; then
      remotes=$(git remote)
      # Remove remote branches
      for remote in $remotes
      do
        branches=$(echo "$remote_branches" | grep "$remote/" | sed "s/$remote\/\(.*\)/:\1 /g" | tr -d '\n')
        git push $remote $branches
      done
    fi

    if [ "$local" == 1 ]; then
      # Remove local branches
      locals=$(echo "$local_branches" | sed 's/origin\///g' | tr -d '\n')
      if [ -z "$locals" ]; then
        echo "No branches removed."
      else
        git branch -d $(echo "$locals" | tr -d '\n')
      fi
    fi
  fi
fi

如何在PowerShell控制台中删除合并的分支

git branch --merged | %{git branch -d $_.Trim()}

如果要排除master或任何其他分支名称，可以使用PowerShell Select String这样进行管道，并将结果传递给git branch-d：

git branch -d $(git branch --merged | Select-String -NotMatch "master" | %{$_.ToString().Trim()})

如果您使用的是Windows，您可以使用Windows Powershell或Powershell 7以及Out GridView来创建一个漂亮的分支列表，并用鼠标选择要删除的分支：

git branch --format "%(refname:short)" --merged  | Out-GridView -PassThru | % { git branch -d $_ }

单击“确定”后，Powershell会将这些分支名称传递给gitbranch-d命令并删除它们

$ git config --global alias.cleanup
'!git branch --merged origin/master | egrep -v "(^\*|master|staging|dev)" | xargs git branch -d'

（为便于阅读，拆分为多行）

调用“gitcleanup”将删除已合并到origin/master中的本地分支。它跳过master、staging和dev，因为我们不想在正常情况下删除它们。

将其分解为以下内容：

git-config--全局别名清理这将创建一个名为“cleanup”的全局别名（在所有回购中）这个在命令的开头，我们将使用一些非git命令作为别名的一部分，因此我们需要在这里实际运行bash命令git branch—合并的原始/主此命令返回已合并到原始/master的分支名称列表egrep-v“（^\*|master|staging|dev）”这将从已合并的分支列表中删除master、staging和dev分支。我们不想删除这些分支，因为它们不是功能。xargs git分支-d这将为每个未合并的分支运行gitbranch-d xxxxx命令。这将逐个删除本地分支。
