First USE STRICT!!!

Having said that, let's try again: 

use strict;
use IO::File;

my $owo = IO::File->new('owo.txt') or die "no open $!";
my %hash  = ();
my @list  = ();

# updated, i was on crack or something - i actually said
# to localize $/ to slurp the contents into an array . . . DOH!
my @ary = <$owo>;

foreach my $item (@ary) {
    push(@list,$item) unless $hash{$item}++;
}

print join("\n", @list), "\n";

and that's it!

Second pointer, i like IO::File, you don't have to use it, but if you like OO style, i highly recommend it.

Third, go buy The Cookbook . . . that's where i learned to do this. :)
