Question

I have a WordPress parent theme and multiple WordPress website (all on the same filesystem) that use it. So how do I make sure with Git that each instance of the parent theme is synced with the version on Github? Without having to pull each instance individually.

You’ve asked how to keep multiple local repository clones up-to-date without having to pull each instance individually. Carl-Eric has addressed how to efficiently store multiple repositories on your filesystem. Here are some suggestions on keeping them up-to-date:

One solution would be to set up a post-merge hook in one of the repositories that iterates across the others and performs the pull operation:

#!/bin/sh

unset GIT_DIR
for repo in /path/to/repo1 /path/to/repo2; do
   ( cd $repo && git pull)
done

The post-merge script is run after a git pull operation.

Having said that, the simplest option would be to have a single clone of the repository and then symlink to it from the other locations.
