How to write a shell script that starts tmux session, and then runs a ruby script

I want to write a shell script that does this:

• Second, run a ruby script called \"run.rb\" INSIDE the tmux session

You could use teamocil to do this easily. You could just create a YAML file:

windows:
  - name: rubysession
    root: ~
    layout: tiled
    panes:
      - ruby run.rb; tmux detach

If you named it 'rubysession.yml' then run:

teamocil rubysession

And that would work perfectly for your purpose and require no hacks. Also teamocil is awesome for loads of other uses!
