Subject: Re: Directory.entries problems with while loops

I've got to say, this is the least Ruby-ish Ruby I've ever seen!  
Someone has already pointed out Dir.glob, and that's probably the  
best approach, but even assuming you don't have that you can do:

   array = Dir.entries(File.dirname("directory.rb")).grep(/tlb/)

Even if, for some strange reason, you needed to write the loop  
yourself, you could simplify it to:

   array = []
   direc.each do |file|
     array << file if file =~ /tlb/
   end

Ruby has a lot of powerful methods for operations on Arrays. You  
should have a good read through the docs for Array and Enumerable!
