Shortcut for OSX dock to run irssi in tmux with iTerm2
I run irssi inside a tmux session on OSX. I often close the terminal as I usually get notified by growl about important stuff. I don't want to open a terminal and write a command every time I want to check IRC.
1. Create a shell script with the following content
#!/bin/zsh /usr/local/bin/tmux attach -d -t irssi || /usr/local/bin/tmux new -s irssi irssi
