I've gotten into it recently but actually not because LLMs. Actually I find them unhelpful here. The reason I've gotten into it is because I wanted to make a bunch of install scripts for programs I want on fresh boxes. Mostly it's been fun. Seeing what I can do with curl, sed, awk, regex, and bash scripting. I'm often finding that I can do a ton of things in a single line where I would have done a lot more if I wrote it in python or something else. Idk, there's just something very fun about this.
Though what's been a little frustrating is that there's anti scraping measures and they break things. But they're always trivial to get around, so it's just annoying.
A big reason LLMs and up failing is that I need my scripts to work on osx and nix machines. So it's always suggesting things to me that work on one but not the other. It seems to not want to listen to my constraints and grep is problematic for them in particular. Luckily man pages are great. I think they're often over looked.
