$ ri IO#fileno
-------------------------------------------------------------- IO#fileno
      ios.fileno    => fixnum
      ios.to_i      => fixnum
------------------------------------------------------------------------
      Returns an integer representing the numeric file descriptor for
      ios.

         $stdin.fileno    #=> 0
         $stdout.fileno   #=> 1
