Are you sure this pair of redirections does what you think it does? :-)
You know that if tmux is running you can use choose-session command to
select a session?
Something like:
(tmux attach\; choose-session) || tmux new
Will attach and let you choose if there are existing sessions, or create
a new one if not. Although I realise yours does a little more.
