view story

http://ubuntuforums.org – I have added the following to my .bashrc to start when I open a terminal: Code: [[ $TERM != "screen" ]] && exec tmux I would like to have tmux start with the equivalent of "C-b %" (in my case "C-a %" as I changed the keymapping in my tmux.conf). This should open two panes, right next to each other. (Hardware)
