That's not really a ChatGPT issue, people pasting in slightly wrong commands (or right commands in the wrong folder) is a tale as old as time - well, as old as linux at least. Short of saying that nobody who's already an expert should ever touch a CLI, the lesson from that story is "be as careful as possible, then be more careful, and also have backups of everything" not "don't use a LLM to help".
Yeah, that exact same problem could easily affect someone who spent hours cobbling together the same awk script from Google searches and StackOverflow.
I'm far from an expert so you should probably ask someone other than me. But my two cents would be not to paste any code until you have understood it, or unless it's written by a source you trust, or alternatively only paste it somewhere you don't care - when I'm playing around testing stuff I might not fully understand on a linux server I do it on a VPS that's unimportant to me, and that if I mess it up I can very easily restore it back to a clean OS install and I have a bash script ready to reinstall all software I want & all the profile customisations etc.
