If you aren't using tmux or screen, you probably should be, especially over SSH sessions. They allow you to have multiple consoles open and switch between them, split window, and disconnect from SSH and then reconnect with all your things still open and running (as long as the server stayed running).
As someone who hasn't invested much time into tmux/screen, what are the benefits of it over just using eg; multiple terminal tabsn or using the terminal's built in split windowing? I'm sure there's probably a benefit but I dunno what it is
I agree with everyone else that it's great on remote systems, but the reason I use it locally too is because I can set up all a project's "tabs" with just one command. I have dozen-line scripts for each client/project that will either create or attach to a tmux session, and when creating set up all the windows how I want: setting their names, cd'ing, opening psql, tailing a log, changing the bottom color (green for development, yellow for staging, red for production), etc. For Rails work I typically have separate windows for models, controllers, views, stylesheets, and javascripts. It makes it really easy to get started after a reboot, or just hide projects for a while and bring them back quickly.
