tmux solves the session resumption at a lower level. You can have a connection from home, jump on a train, open your laptop and keep typing and do the same when you get into the office. You don't need to re-auth each time (or deal with delayed disconnects). It works well WITH tmux, not instead of tmux. Which means your solution would be something like: while true; do ssh -t ${HOST} tmux a done But that lacks the other benefits, especially having to wait for the session to timeout..
