I'm trying to figure out a way to sort large apache log
files in perl. I've got something worked out but I
think it can be made better. Here is what I have so far:
#!/usr/bin/perl -w

use Date::Calc qw|Date_to_Time Decode_Month|;

foreach $file (@ARGV) {

    die("This is not a file: $!") unless (-f $file);

    open(FILE, $file);
    push(@logs,<FILE>);
}

@sorted= map {$_->[0]}
    sort {$a->[1] <=> $b->[1]}
        map{
            chomp;
            my $stamp = get_timestamp($_);
            [$_,$stamp]
        } @logs;

foreach (@sorted) {
    print "$_\n";
}


sub get_timestamp {

    my $line = shift;

    $line =~ /\[(.*) -\d+\]/;

    my $tempdate = $1;

    my ($day,$mon,$year,$hour,$min,$sec) = 
                 $tempdate =~ /(\d+)\/(\w+)\/(\d+):(\d+):(\d+):(\d+)/;

    $mon = Decode_Month($mon);

    my $stamp = Date_to_Time($year,$mon,$day,$hour,$min,$sec);

}
