If I had a hash, I'd have to have a key and a value though. I'm just looking for one or the other. I suppose I could have key value pairs in the %SAN hash like so:
Perl hashes are pretty versatile. As Wags was saying, just stick each item in the hash under the unique key you want. The value doesn't matter at all. In the end, pull the keys and boom, problem solved. Let's look at an example:
my @words = qw(dog cat dog lizard dog wombat dog);
my %seen;
foreach (@words) {
$seen{$_}++;
}
my @words = keys %seen;
print "@words\n"; # only prints one dogHope that helps.
