my @array = ('a','b','a','x','x','b','c');
my %uniq = ();

@uniq{@array} = ();
@array = keys %uniq;

print "@array"; # prints: a b x c (not necessarily in this order though)

I just wanted to add one thing even though perlplexer's code works great, only because I thought this way is easier to remember.

@uniques = grep(!$seen{$_}++, @array);
print "@uniques";

That code keeps the order the same also.

No offense or anything perlplexer, I think your awesome.
