Since you mention TextEdit, I presume you are on a Mac. Also, since  
you mention irb, I presume you are familiar with Terminal. Here is an  
easy way to run a Ruby script in Terminal. After writing your hello  
script in TextEdit save it as hello.rb. Now in terminal at a fresh  
prompt, type "ruby " (without the quotes and remember to include the  
space after "ruby"). Now drag hello.rb into to Terminal and hit  
return. The text "Hello World" should appear.
