I had a spark of glee seeing another fish shell user.
I used "job control" a lot but never called it that. And I mostly would background or foreground tasks. I didn't know about a few of those additional commands talked about. Disown will be pretty handy.
Oh God, this reminds me of recurring nightmares I would have when potato truck driving 15 hour days. I'd be wondering why my truck lights weren't working and would start trying to pump the breaks, but that wasn't working either. Turns out I was kicking the shit out of my bed in the middle of the night. Even after getting out of bed I thought I was wandering around the cab of the truck thinking it was out of control until somehow some part of me got to the light switch and dispelled the dream.
A bed like this would just make that worse.
