Well, I’m talking about my team members at my dayjob. I’m a software engineer.

But it’s also a lot less explicit than what you’re probably imagining. It’s rather that we have a meeting and realize that a problem re-occurred which we thought we solved months ago. So, then everyone starts collectively scratching their head and somewhat rhetoric questions might be thrown into the room, i.e. “Oh man, do you still remember how we did that?”.

Then I might start typing the command how I think it would probably begin, often with the intention of then putting --help at the end to try to jump-start my memory. And then that’s where Fish often jumps in and tells me that I’m apparently typing the exact beginning letters of the command that we used a few months ago.
Sometimes this even happens when I have no recollection that I ran a given command before, and someone’s just generally asking how to do a certain task…

I’ve shared commands with friends and they ask for them again. I imagine similar context here
