删除所有本地 git 分支 [英] Delete all local git branches

问题描述

我遵循开发流程，为每个新功能或故事卡创建一个新的本地分支.完成后，我将分支合并到 master 中，然后推送.

I follow a development process where I create a new local branch for every new feature or story card. When finished I merge the branch into master and then push.

由于懒惰或健忘的组合，随着时间的推移往往会发生的事情是，我最终得到了大量本地分支，其中一些(例如尖峰)可能尚未合并.

What tends to happen over time due to a combination of laziness or forgetfulness, is that I end up with a large list of local branches, some of which (such as spikes) may not have been merged.

我知道如何列出所有本地分支，也知道如何删除单个分支，但我想知道是否有一个 git 命令可以让我删除所有本地分支?

I know how to list all my local branches and I know how to remove a single branch but I was wondering if there was a git command that allows me to delete all my local branches?

下面是 git branch --merged 命令的输出.

Below is the output of the git branch --merged command.

user@machine:~/projects/application[master]$ git branch --merged
  STORY-123-Short-Description
  STORY-456-Another-Description
  STORY-789-Blah-Blah
* master

所有尝试删除用 grep -v * 列出的分支(按照下面的答案)都会导致错误:

All attempts to delete branches listed with grep -v * (as per the answers below) result in errors:

error: branch 'STORY-123-Short-Description' not found.
error: branch 'STORY-456-Another-Description' not found.
error: branch 'STORY-789-Blah-Blah' not found.

我正在使用:
git 1.7.4.1
Ubuntu 10.04
GNU bash，版本 4.1.5(1)-release
GNU grep 2.5.4

I'm using:
git 1.7.4.1
ubuntu 10.04
GNU bash, version 4.1.5(1)-release
GNU grep 2.5.4

推荐答案

'git branch -d' 子命令可以删除多个分支.因此，简化@sblom 的答案，但添加一个关键的 xargs:

The 'git branch -d' subcommand can delete more than one branch. So, simplifying @sblom's answer but adding a critical xargs:

git branch -D `git branch --merged | grep -v * | xargs`

或者，进一步简化为:

git branch --merged | grep -v * | xargs git branch -D 

重要的是，正如@AndrewC 所指出的，不鼓励使用 git branch 编写脚本.为了避免它使用类似的东西:

Importantly, as noted by @AndrewC, using git branch for scripting is discouraged. To avoid it use something like:

git for-each-ref --format '%(refname:short)' refs/heads | grep -v "master|main" | xargs git branch -D

谨慎删除！
