How to capture a git commit message and run an action
提问by James Nine
I'm new to git and I want to be able to capture the commit message after a push to the origin/master and run a bash script (on the server) based on what the string contains.
我是 git 的新手，我希望能够在推送到原点/主站后捕获提交消息，并根据字符串包含的内容运行 bash 脚本（在服务器上）。
For example, if my git commit message says: [email] my commit message
例如，如果我的 git commit 消息说： [email] my commit message
If the commit message contains [email]then do a specified action, otherwise, don't do it.
如果提交消息包含[email]则执行指定的操作，否则不执行。
Here's a sample bash script I'm thinking of using in the post-receivehook:
这是我想在post-receive钩子中使用的示例 bash 脚本：
#!/bin/bash
MESSAGE= #commit message variable?
if [[ "$MESSAGE" == *[email]* ]]; then
echo "do action here"
else
echo "do nothing"
fi
Basically all I need to know is what the variable name for the commit message is, to use in the above bash script? Also, I'm not sure if this is the right hook to do this or not.
基本上我需要知道的是提交消息的变量名称是什么，在上面的 bash 脚本中使用？另外，我不确定这是否是执行此操作的正确方法。

I think I figured out the answer to my own question; the variable can be obtained using the git-logcommand:
我想我找到了自己问题的答案；可以使用以下git-log命令获取变量：
git log -1 HEAD --pretty=format:%s
so, my script would be:
所以，我的脚本是：
#!/bin/bash
MESSAGE=$(git log -1 HEAD --pretty=format:%s)
if [[ "$MESSAGE" == *\[email\]* ]]; then
echo "do action here"
else
echo "do nothing"
fi
I hope this might help anyone else who is searching for the answer.
我希望这可以帮助其他正在寻找答案的人。
