cdgems.sh

function cdgems() {
  /usr/bin/osascript -e "tell application \"System Events\" to tell process \"Terminal\" to keystroke \"t\" using command down"
  /usr/bin/osascript -e "tell application \"Terminal\" to do script with command \"cd $GEM_HOME/gems\" in window 1"
  /usr/bin/osascript -e "tell application \"System Events\" to tell process \"Terminal\" to keystroke \"k\" using command down"
  return 0
}

alias cdgems=cdgems

This will alias the command 'cdgems' to open a new terminal tab in the gems directory relative to RVM

Just add to your .bash_profile

Wouldn't it be better to alias cdgems to 'pushd $GEM_HOME/gems'? That way you could do what you need to, then run "popd" to get back to what you were doing.

Alternatively, you could hit Command-T and then cdgems. The osascript seems a little over the top.

@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
