Question

when I push something to my GIT repository, the post-receive hook is triggered and executes some scripts. Is it possible doing something before the execution these scripts if (and only if) a specific file is changed respect to the previous push (for example .sql file)?

Thanks

In the same post-receive hook as a first step or in a pre-receive or update hook, you can use

git diff-tree --name-status -rz

and pass in the new and old ref that are passed in to the hook ( either stdin or arguments) and get the files, check for modified – M – status in the output and do what you need.
