Git Post-Commit Hook

Question

Git newbie here. I want a post commit hook that when run will copy the latest code from the repository to a different server in a new folder. The folder name should be what I wrote in the git commit comment.

Is this possible?

Since you don't look so certain as to which hook you need, according to the coments, I'm posting an answer based on post-receive hook. This is a server-side hook that will ran after everything is received in the server, after a push. A post-commit hook would be client-side, and would run after every commit (for more info about git hooks, see https://git-scm.com/book/it/v2/Customizing-Git-Git-Hooks).

Assuming a bash script, you can use:

MESSAGE=`git log -1 HEAD --pretty=format:%s`

to retrieve the last commit message, and work from there to create your script. It's also possible to retrieve every commit message included in that push, by using:

while read oldrev newrev ref
do
    MESSAGE=`git log -1 $newrev --pretty=format:%s`
    doSomethingElse...
done

As for copying it to somewhere else, you can use anything you'd use in other scripts, like scp, rsync... Just clone/update a local copy in a temp dir and sync it to your remote location.
