Shortcut for OSX dock to run irssi in tmux with iTerm2

Synopsis

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.

The solution

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

2. Create a profile in iTerm2 with the name `irssi` and the shell script as the run command

3. Create an AppleScript with the following content and save as `irssi.app`

tell application "iTerm"
    activate
    set myterm to (make new terminal)
    tell myterm
        launch session "irssi"
    end tell
end tell

4. Drag `irssi.app` to the dock

5. Add a nice icon

Ways to make it nicer

it should be possible to set the tmux commands directly as the iTerm session command but that somehow didn't work for me
