Easy way: system("ls").

Harder way, use the Dir class or the Find module. Dir is one of the core 
classes. Find isn't, but it is part of the standard library so all you 
have to do to use it is execute

require 'find'

in irb before using any of the Find methods. Both Dir and Find are 
documented here: http://www.ruby-doc.org/
