Subject: Re: Passing folder as argument ARGV?

First ARGV is an array of all arguments to Ruby program. So regardless
of which OS you are using, do something like the following:

  my_var = ARGV[0]
  dir = File.expand_path(my_var)
  Dir["#{dir}/*"].each {|f| puts f }

Or depending on wether you need the full file path name or just bare
filename, something allong the following:

  p Dir["#{File.expand_path(my_var)}/*"]
  p Dir["#{File.expand_path(my_var)}/*"].each.map { |f| File.basename(f)
}

Regards, igor
