And then there is of course Dir[] as well.  For simple outputting it's 
probably easier:

ruby -e 'puts Dir["**/*"]'

Btw, the process is not called "parsing".  In this case I'd rather use 
the term "traversing".  "Parsing" usually means read a byte sequence and 
determine its structure according to some grammar.

Kind regards
