I want to start tmux with two panes and have one of them running a program:
 [ishpeck@kiyoshi ~]$ cat ~/.tmux.conf
split-window -h top
[ishpeck@kiyoshi ~]$ tmux
When tmux comes up, it displays the error:
/home/ishpeck/.tmux.conf:1: no current target
With tmux still open, I hit prefix then type ":source ~/.tmux.conf " and it works as expected. Why does it never work at start-up, but works fine when I'm sourcing it?
