About how to clone a Prestashop instance - Nobody comes after the last

Lately, I’ve been helping my neighbor with his Prestashop website. I’ve learned a few tricks, like editing the overall appearance of the site, making and restoring backups in a limited environment, but my best invention has been cloning the Prestashop instance to have a test version where I can try things out without fear of breaking anything. Here’s the code for anyone who might find it useful, licensed under GPL 3.

You can see the code here, too: https://gist.github.com/axelei/dafd305213ed1b2655545f06edfbc905

The implementation could undoubtedly be improved—using a more suitable language or more advanced tools—but this is the solution I came up with given the constraints of an environment lacking many essential utilities and commands.
