Subject: ruby in cmd

I am new to Ruby and am trying to run a piece of code from Programming
Ruby in cmd. When i run in cmd >ruby Song.rb, I don't get any output.
But I can get the result I expected when I run in irb. Can anyone help
me on this?

class Song
    def initialize(name , artist, duartion)
        @name = name
        @artist = artist
        @duration = duartion
    end

    def to_s
     "Song: #{system @name}--#{@artist} (#{@duration})"
    end

    def name
        @name
    end

    def artist
        @artist
    end

    def duration
        @duration
    end
end


aSong = Song.new("NAF", "AS", 300)
aSong.to_s
aSong.artist
aSong.name
aSong.duration
