Sorry to disappoint, but no can do on that agreement. The web is full of bad advice for shell scripting one liners, because too many people fumble their way to a semi-workable inefficient solution for their specific problem, then instead of attempting to refine it and make it better by removing extraneous options they publish it as is to a blog post or gist. The result is that LLMs ingest a lot of subpar commands.
I’ve tested this many times. It is rare that an LLM returns me a one-liner that I can’t immediately see how to improve.
