  p Dir["#{File.expand_path(ARGV[0])}/*"].each.map { |f|
File.basename(f) }

With the above code you can give the folder name to your program, like
the following:

  $ ruby get_files.rb folder_name

Use {{ p ARGV }} or {{ puts ARGV }} to see what is in it. If you run the
above {{ $ ruby get_files.rb }} in the terminal or console on the
command line then ARGV[0] will have in it the string 'folder_name'. If
you run {{ $ ruby get_files.rb *.rb }}, each element in the ARGV array
will have one file from your current directory.
