From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I tried and failed to get an LLM to write jq code to do a regex based matcher for finding if one json object was a subset of another.
Gave up and learned it enough to get it going. jq is nutso powerful.
I don't understand how regex comes into it? Sounds tricky though!
Basically "does this JSON object contain at least these two properties, and is the value of one particular properties a string of digits followed by the letter 'Z'", for example.
