I use tmux as my screen multiplexer, and in the past, I used control-A d to disconnect and tmux a -d to reattach to the session. This gets cumbersome if I haven’t created a tmux session yet, since tmux a -d will give me an error that no session exists. Aliases to the rescue To help start sessions, and now name them, I use the following alias: alias tma="tmux new -ADs" To create a session named main or re-attach to a disconnected session, I can now type tma main.
