From the Perl Cookbook: 
my @list = qw(some list of of non unique words);
my %unique = ();
foreach my $item (@list) {
    $unique{$item}++;
}

The keys of %unique are the unique values.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
