I have a question similar to this guy but more specific.

I want to do this in a single tmux.conf file, without any key-bindings to load specific sessions per @jasonwryan 's answer.

So, how do I do this? I set my tmux.conf:

new  -s mySession -n myWindow
neww -n foo/bar foo
splitw -v -p 50 -t 0 bar
selectw -t 1 
selectp -t 0

but it doesn't split the window when I start tmux.

Update: I don't think the attach is working. If I ditch the second 'foo' window and simplify my tmux.conf :

# set panes the way I want them
# if I started tmux by just running 'tmux' in command line, it automatically creates session(0) so...

new -s mySession -n myWindow    # ... create new session (1) with new window (0)
select-window -t myWindow       # select myWindow (0)
splitw -v -p 50 -t myWindow     # split myWindow (0) vertically into halves(50 percent)

attach -s mySession             # error usage: attach-session [-dr] [-t target-session]
attach-session -t mySession     # so this doesn't work either
switch -t mySession             # nor doesn't work

So what am I missing? If I manually switch sessions once tmux launches by doing CTRL+b s and then selecting the mySession, the panes are split and everything is great. So how do I attach to or switch to mySession from session(0)?

this worked once I made the changes in my Update, but I should be able to do the "attach" INSIDE the tmux.conf, right? – tir38 Apr 3 '13 at 21:44

After you've created the new session, create a new window, and split a window into 2 panes, you still need to attach to the session. Add

attach -s mySession

to the end of the commands you show above.
