Can someone please tell me whether there is anything wrong with the logic of the following bit of code. 
my $new_outputfile = $outputfile."_B";

open (RESULT_FILE, "<$outputfile");
open (CLEANED_RESULT, "+>$new_outputfile");

our @data = <RESULT_FILE>;
chomp @data;

my %seen; 

for ( @data) { 
  next if $seen{$_}++;
  print CLEANED_RESULT "$_\n";
}

remove $outputfile or warn $!; 
rename "$new_outputfile", "$outputfile"  or warn $!;

It does not appear to be doing what I ask of it.

Update: The output file is present as a directory location and file name like: C:/Perl_activate/filename.txt
