Hi, I need to remove duplicate entries from a file then print to a new output file. The following works, but how can i how print the non-duplicated hash to a file? 
while (<>){  # take file with duplicate lines
chomp $_;
/(\d+)$/;

push @array, $1;

          }



my %uniques;

foreach my $key(@array){

   $uniques{$key}++;
                       }

thanks
