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。

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'

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

如果要删除合并的分支，则只需删除远程跟踪分支，除非您另有说明。

因此，要删除这些分支，您可以通过

git branch--remote--合并原始/主|egrep-v“（^\*|master|development）”|cut-b 10-|xargs git push--删除原始

这将删除除主分支和开发分支外的所有合并分支（合并到主分支）。

要删除远程上已合并的所有分支，请执行以下操作：

git branch -r --merged | grep -v master | sed 's/origin\//:/' | xargs -n 1 git push origin

在Git的最新版本中

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

UPDATE（通过@oliver；因为不适合注释，但已经有足够的答案了）：如果您在分支ABC上，那么ABC将出现在git branch-r--merged的结果中，因为未指定分支，所以分支默认为当前分支，分支始终符合自身合并的条件（因为分支和自身之间没有区别！）。

因此，指定分支：

git branch -r --merged master | grep -v master ...

OR第一个结账主机：

git checkout master | git branch -r --merged | grep -v ...

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
