Subject: Itterating through one's path(s)

I'd like to see if I can itterate through the directories
of my PATH (or $PATH for Unix-based systems) using blocks.

#!/usr/bin/ruby -w path =
ENV['PATH'].split(File::PATH_SEPARATOR) 

path.each{|zz| Dir.new zz}

There's an example of using nested for loops in 
file:///usr/share/doc/ruby-1.8.4/sample/dir.rb
....
# directory access
# list all files but .*/*~/*.o
dirp = Dir.open(".")
for f in dirp
  case f
  when /^\./, /~$/, /\.o/
    # do not print
  else
    print f, "\n"
  end
end
dirp.close
