Git post-receive to checkout only those files that have been modified/added in the push?

Question

I have been using post-receive scripts in my git repositories with the following commands to checkout all of the files in the repository:

#!/bin/sh
GIT_WORK_TREE=/var/www/www.example.org git checkout -f

I am wanting to do something similar but only checkout the files that have been modified or added in the push. Once the files have been checked out the post-receive script will then run some other commands on these files and remove the files at the end so that the directory will be empty.

Is this possible?

Answer 1

you can use git diff to give you a list of files

git diff --name-only from..to

in a post-receive hook that'll be I think

git diff --name-only $1..$2

as this hook receives oldrev, newrev and ref on standard input
