删除所有本地git分支

Question

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

删除grep-v\*列出的分支的所有尝试（根据下面的答案）都会导致错误：

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

我使用的是:
git 1.7.4.1
ubuntu 10.04
GNU bash,version 4.1.5(1)-release
GNU grep 2.5.4

Answer 1

git branch-d'子命令可以删除多个分支。因此，简化@sblom的答案，但添加了一个关键的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指出的，不鼓励使用Git Branch编写脚本。为了避免这种情况，请使用以下内容：

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

$ mkdir br
$ cd br; git init

$ git branch --merged | grep -v \* | xargs
