Thanks!
I found the most value in some of the additional tricks shown in the article (like the “pretty print JSON stored in the clipboard) over the introduction/tutorial aspect; there are hundreds of these “look, I figured out how to do a handful of interesting things in jq so let me share with you all” tutorials floating around and most of the basics are redundant among those by now.
If jq’s documentation had some basic tutorials it would probably be a better authoritative source for this information.
Until then, as said, thanks for preparing and sharing this!
