KW.pm The Schwartzian Transform #17

Another example:

         @sorted_names = 
           map { $_->[0] }
           sort { $b->[1] <=> $a->[1] } 
           map { [ $_, -M $_ ] } 
           readdir D;
  • -M is the file-test for last-modified time

  • In this case, we don't need to save the time, we just save the filename.
