如何删除已合并的分支?我可以一次删除所有分支,而不是逐个删除每个分支吗?

如果您使用的是带有git插件的OhMyZSH,则可以使用gbda别名。

对于我来说,gitbranch--merged不显示通过GitHub PR合并的分支。我不确定原因,但我使用以下行删除所有没有远程跟踪分支的本地分支:

diff <(git branch --format "%(refname:short)") <(git branch -r | grep -v HEAD | cut -d/ -f2-) | grep '<' | cut -c 3- | xargs git branch -D

说明:

gitbranch--格式“%(refname:short)”提供本地分支列表gitbranch-r | grep-v HEAD | cut-d/-f2-提供远程分支列表,过滤掉HEADdiff<(…)<(grep“<”筛选第一个列表中存在但第二个列表中不存在的分支cut-c 3-给出从第3个字符开始的行,从而删除前缀<xargs git branch-D针对每个分支名称执行git branch-D

或者,可以这样避免grep-v“<”:

diff --old-line-format="%L" --new-line-format="" --unchanged-line-format="" <(git branch --format "%(refname:short)") <(git branch -r | grep -v HEAD | cut -d/ -f2-) | xargs git branch -D

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())

对于那些使用Windows并喜欢PowerShell脚本的人,这里有一个删除本地合并分支的脚本:

function Remove-MergedBranches
{
  git branch --merged |
    ForEach-Object { $_.Trim() } |
    Where-Object { $_ -NotMatch "^\*" } |
    Where-Object { -not ( $_ -Like "*master" -or $_ -Like "*main" ) } |
    ForEach-Object { git branch -d $_ }
}

或者简称:

git branch --merged | %{$_.trim()}  | ?{$_ -notmatch 'dev' -and $_ -notmatch 'master' -and $_ -notmatch 'main'} | %{git branch -d $_.trim()}

公认的解决方案很好,但有一个问题,它还删除了尚未合并到远程的本地分支。

如果你查看的输出,你会看到

$ git branch --merged master -v
  api_doc                  3a05427 [gone] Start of describing the Java API
  bla                      52e080a Update wording.
  branch-1.0               32f1a72 [maven-release-plugin] prepare release 1.0.1
  initial_proposal         6e59fb0 [gone] Original proposal, converted to AsciiDoc.
  issue_248                be2ba3c Skip unit-for-type checking. This needs more work. (#254)
  master                   be2ba3c Skip unit-for-type checking. This needs more work. (#254)

分支bla和issue_248是将被默默删除的本地分支。

但您也可以看到单词[gone],它表示已被推到远程(现在已不存在)的分支,因此表示可以删除分支。

因此,原始答案可以更改为(拆分为多行以缩短行长度)

git branch --merged master -v | \
     grep  "\\[gone\\]" | \
     sed -e 's/^..//' -e 's/\S* .*//' | \
      xargs git branch -d

以保护尚未合并的分支。此外,也不需要为master提供保护,因为它在源位置有一个远程,不会显示为已删除。

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。
