Tmux allows you to start multiple windows and send commands to them. An example from man tmux - " refresh-client -t/dev/ttyp2 rename-session -tfirst newname set-option -wt:0 monitor-activity on new-window ; split-window -d bind-key R source-file ~/.tmux.conf \; \ display-message "source-file done" " Screen has no equivalent besides manually using the keybinds. I believe tmux has some better mechanics around the attach/detach but it eludes me atm what was better. Basically what made me switch in the first place from screen to tmux was wanting a split window watch compile and a logfile to run automatically with one command. Hard with screen and easy with tmux.
