This is as inefficient as using File.foreach because it will read the 
whole file.  I believe Ted was looking for a more efficient solution.

Ted, if you want to do this in Ruby and not resort to tail you can use 
IO#seek to seek to the end of the file and read backwards until you have 
read more than one line.

Kind regards
