I tried it - didn't like it. Had an LLM work on a backup script since I don't use Bash very often. Took a bunch of learning the quirks of bash to get the code working properly.

While I'll say it got me started, it wasn't a snap of the fingers and a quick debug to get something done. Took me quite a while to figure out why something worked but really it didn't (LLM using command line commands where Bash doesn't interpret the results the same).

If its something I know, probably wont use LLM (as it doesn't do my style). If it's something I don't know, might use it to get me started but I expect that's all I'll it for.

Can I ask which agent/model you used? I'm similarly irritated with shell script coding, but find I have to make scripts fairly often. My experience using various models but latterly Claude Code has been quite different -- it churned out pretty much what I was looking for. Also old, fwiw. I'm older than all shells.
