Ok, maybe I'm doing it wrong, but...

To restore a session from the bash prompt (after a fresh reboot), I run:

$ tmux new-session

Then I hit prefix ctrl-r

This restores all of my windows, but it also leaves me with the 'extra' window that was created with new-session.

I kill the new window. This drops me out of tmux and back to the bash prompt. Then I have to run

$ tmux attach

Now I'm finally in my restored session without the extra new-session window.

Is there any way to do all of this in one step? I'd love to have a bash script that does the following:

• attaches to a tmux session if it is running
• restores the saved session if no session is running
