Since you're using TextMate (as I do), I recommend running Ruby code  
from within TextMate. No need to bother with Terminal.

1. Use Bundles>Ruby>Run to run your script. Output goes to a RubyMate  
window which will pop up.

2. Try the following:

   class Book
     def initialize(title, author, pages)
       @title   = title
       @author  = author
       @pages   = pages
     end
   end

   book = Book.new("Ruby Tutorial", "Dave", 831)
   book.inspect # =>

Note the '# =>' added to the last line. Choose Ruby>Evaluate and  
Update '# =>' Markers from the Bundles menu. The last line will  
change to

   book.inspect # => "#<Book:0x25454 @author=\"Dave\", @title=\"Ruby  
Tutorial\", @pages=831>"

There are shortcuts for these bundle commands, and there are several  
other aids to evaluating Ruby code built-in to the TextMate Ruby  
bundle. I think you will find TextMate makes it easy to explore Ruby  
without constantly switching back and forth to Terminal.
