Using a hash works as already mentioned. For completeness, you should also know another standard trick. You can sort a list of indices:

    my @urls= qw( yahoo.com ebay.com google.com );
    my @links= qw( yahoo    ebay     google );
    my @idx= sort { $urls[$a] cmp $urls[$b] } 0..$#urls;
    # Now @urls[@idx] is sorted
    # and @links[@idx] is in the same order.
    # You could loop in that order like so:
    for my $i (  @idx  ) {
        print "$urls[$i]\t$links[$i]\n";
    }
    # Or you could just sort the arrays in place:
    @urls= @urls[@idx];
    @links= @links[@idx];

This trick can be useful for speeding up a lengthy sort operation. It is also a great way to keep one or more lists sorted in more than one order at once.
