If this is your working environment, it sounds like quite an unusual place.

I literally can't imagine generating a script with an LLM without testing it at all.

Bash is one of those situations where LLMs can do really well. No human on Earth can remember all of the commands and even fewer humans can remember all of the switches for all of the commands.

This kind of remembering, searching, and assembling is exactly what LLMs are good at - as long as you're not writing a gigantic build system with hundreds of moving parts, in which case you should probably be using something more streamlined anyway.
