Mosh is excellent. It lets remote sessions survive (well, automatically and transparently recover from) disruption that reliably kills ssh.

I basically don't use ssh at all any more for interactive sessions, because I'm sick of a few lost packets on wifi or a weak cell signal dropping my connections and forcing me to start over.

Tmux, I used to use and eventually abandoned. I decided I didn't need two keyboard-based window managers (I use Spectacle on Mac) and the one that was only for shells was the one that could go. I have replaced it with nothing, so far, aside from that I just open more Terminal.app windows now (I also used to use iTerm2, for years, until it dawned on me that I was using exactly nothing in it that's not also provided by Terminal.app, and the latter's got better input latency, so I was suffering an extra installed program and slightly less responsive typing for no reason at all)

Mosh does not support OSC52, so it's a barrier to getting copy/paste to work.

And case in point, mosh is another terminal layer, it's also a multiplexer of sorts.

I've used mosh a lot but it's just interesting to note it's in the same category as screen and tmux

On mobile so I’m not sure which case OSC52 applies to, but I use mosh+tmux 8-10 hours a day. Both bracketed paste and tmux selection setting local clipboard work fine

it sort of does support it, except it doesn't work with tmux.

Haha I think you have the history backwards here. Tmux was created as a replacement for screen when it was 20 years old! Speaking as someone with ‘set -g prefix c-a’ in their .tmux.conf because my muscle memory is so used to the screen hotkeys.

GNU screen was released in 1987.

tmux was created in 2007.

Hey maybe I do! Great to learn the history here. Regardless, my point is that Byobu is very nice compared to either. That may now be lost due to my careless comment.

It's seamless until you want to scroll.
