    Same thing, just slightly shorter (and maybe clearer):

    #! /usr/bin/perl use strict; use Data::Dumper; my %hash; /^(\d+).*/ and $hash{$1}++ for <DATA>; print Dumper \%hash; __DATA__ 817 5:00 817 5:00 817 5:15 123 4:45 817 5:30 495 7:45

    Those who know that they are profound strive for clarity. Those who
    would like to seem profound to the crowd strive for obscurity.
