Find Git branch name in post-update hook
提问by user489998
I'm executing a programme to alert CruiseControl each time an update is sent to our remote repository. I'm using a Git post-update hook for this.
每次更新发送到我们的远程存储库时，我都会执行一个程序来提醒 CruiseControl。为此，我正在使用 Git 更新后挂钩。
It would be great if I could find out which branch had been committed so I could use that to inform CruiseControl which branch to build. Is there any way to access the branch name within a post-update hook?
如果我能找出哪个分支已经提交，那么我就可以使用它来通知 CruiseControl 要构建哪个分支，那就太好了。有没有办法在更新后挂钩中访问分支名称？

The first parameter to the post-update hook is the branch reference in full - for instance I see 'refs/heads/master' for a push to 'origin master'. So an example hook script that just prints the branch modified is:
post-update 挂钩的第一个参数是完整的分支引用 - 例如，我看到 'refs/heads/master' 用于推送到 'origin master'。因此，仅打印修改后的分支的示例钩子脚本是：
#!/bin/sh
branch=$(git rev-parse --symbolic --abbrev-ref )
echo Update pushed to branch $branch
exec git update-server-info
To illustrate, when the above is placed into your remote repository hooks/post-update file the following is printed when performing a push:
为了说明这一点，当上述内容放入远程存储库挂钩/更新后文件时，执行推送时会打印以下内容：
% git push origin master
Counting objects: 5, done
Writing objects: 100% (3/3), 247 bytes, done.
Total 3 (delta 0), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
remote: Update pushed to branch master
To /tmp/xx/a
e02d9cd..ab14a08 master -> master
The new line beginning 'remote:' was output by our hook script.
以“remote:”开头的新行是我们的钩子脚本输出的。
