This assumes you installed sublime text 2. if not - do that here - http://www.sublimetext.com/2
Sublime Text 2 ships with a CLI called subl (why not "sublime", go figure). This utility is hidden in the following folder (assuming you installed Sublime in /Applications
like normal folk. If this following line opens Sublime Text for you, then bingo, you're ready.
The reason why sublime is not shipped default is that it is too long to type. the reason for subl being lame is that it's not a word. textmate is great because I type mate to get along editing whatever directory or file I want. slim is the new mate and gives me those good feelings the way it is typed with few finger movements and has meaning.
ln -s /Applications/Sublime\ Text\ 2.app/Contents/SharedSupport/bin/subl /usr/local/bin/slim
