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()})

我发现最简单的方法是只删除本地分支，而不是远程分支：

$git分支--合并|grep-v主|xargs-n 1 git分支-D

此命令将仅删除已合并到主分支中的分支。如果您不想删除其他分支（例如登台），请小心。

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

下面创建一个别名gitcleanup，其中包含一个可选参数分支。默认情况下，它使用远程源的默认分支。已合并到此中的每个分支都将被删除。还有一个-d/-dryrun选项，用于显示将删除的内容。

安装程序

git config --global alias.cleanup '!COMMAND="git branch -D"; while [[ $# -gt 0 ]]; do case "$1" in -d|--dryrun) COMMAND="echo"; shift; ;; *) MAIN_BRANCH="$1"; shift;; esac; done; MAIN_BRANCH="${MAIN_BRANCH:-$(git symbolic-ref refs/remotes/origin/HEAD)}"; git for-each-ref --merged="$MAIN_BRANCH" --no-contains="$MAIN_BRANCH" --format="%(refname:short)" refs/heads/ | xargs -n1 -r $COMMAND;#'

用法：

git cleanup             # delete all branches that have been merged into origin/HEAD
git cleanup master2     # delete all branches that have been merged into master2
git cleanup master2 -d  # do a dryrun (show names of branches that would be delted)

可读代码

谁能读到那句“oneliner”？好了，给你

COMMAND="git branch -D";
while [[ $# -gt 0 ]]; do
  case "$1" in
    -d|--dryrun)
      COMMAND="echo"; 
      shift; 
      ;; 
    *)
      MAIN_BRANCH="$1";
      shift
    ;;
  esac;
done;
MAIN_BRANCH="${MAIN_BRANCH:-$(git symbolic-ref refs/remotes/origin/HEAD)}"; 
git for-each-ref --merged="$MAIN_BRANCH" --no-contains="$MAIN_BRANCH" --format="%(refname:short)" refs/heads/ | xargs -n1 -r $COMMAND;
#

与其他答案有什么不同？

使用--no contains选项过滤掉标识分支（所有其他被删除的分支都已合并到其中的分支），而不是grep-v（如果您特定于分支并指定refs/heads/master，则效果更好）使用远程HEAD检查默认分支名称具有一个参数，用于指定要用作合并主节点的分支具有干式运行选项

刚刚为此创建了python脚本：

import sys
from shutil import which
import logging
from subprocess import check_output, call

logger = logging.getLogger(__name__)

if __name__ == '__main__':
    if which("git") is None:
        logger.error("git is not found!")
        sys.exit(-1)

    branches = check_output("git branch -r --merged".split()).strip().decode("utf8").splitlines()
    current = check_output("git branch --show-current".split()).strip().decode("utf8")
    blacklist = ["master", current]

    for b in branches:
        b = b.split("/")[-1]

        if b in blacklist:
            continue
        else:
            if input(f"Do you want to delete branch: '{b}' [y/n]\n").lower() == "y":
                call(f"git branch -D {b}".split())
                call(f"git push --delete origin {b}".split())

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')
