@jasonnoble with RVM I have custom gemsets for my different projects. Sometimes I want to jump into them so this will create that new tab and set the pwd to my project's top-level gemset directory. That being said, I fully admit I suck at any/all Bash scripting so there might be a much better way to do this. Someone else has already mentioned rb-applescript

I use it
cd rvm gemdir

bundle open GEM

will open the bundled gem with default editor
