Tmux is another one of those tools whose siren call I'd avoided for a good decade, continuing to rely on GNU Screen. Then, for the last time I reconnected to a split screen and screen lost my splits and tabs - it was enough for me.
Two years ago I finally changed over and I haven't looked back. At this point, when I encounter something where I only have screen I'm rather annoyed by it - and I've set my tmux key mapping to basically mimic what I've been using screen for the last 20 years.
For me, tmux replaced every single feature that I used in screen. On the other hand, I'd be genuinely happy if it existed on the older OSes I randomly have to frequent, even if it's understandably impossible.
The one thing keeping me from switching is the lack of command classes[0]. I want to be able to chain bindings, so "^a s a" does "ssh server-a", and "^a s b" does "ssh server-b".
People keep telling me that tmux is better (though I still don't understand why), but I lean heavily on chained bindings and haven't found a solution in tmux.
Totally fair, and I never missed it because I have a different approach. I always open the shell and execute my commands in it - regardless of screen/tmux, a straight bash shell, or xterms(etc).
I have a crazy amount of automatic generating shell commands, so that I basically need bash --login to trigger anyways.
I have a tmux session that's been running for almost a year with no problems. I don't know how long it will run, but perfect performance for almost a year is good enough for me.
My session has 8 tabs, and one of the tabs (my primary) has 14 sub windows (frames?) showing all kinds of good busy information.
Fair question. My environments are different now, so I have no need to have a session last that long. My longest screen session, like yours was years. My current longest tmux session goes back to April 23 2018.
Admittedly, I'd hope to argue that if I keep sessions open that long I'm the problem.
