I'm not really sure what exactly that would entail. I will post what I have thought of (using an array), although it is not working.


open(DUPS, ">duplicates.txt") or die "Can't open duplicates.txt $!";
for $i (0 .. $#reports){
for $j (0 .. $#reports){
if ($i != $j && $reports[$i] eq $reports[$j]){
print DUPS "\n $reports[$i]";
last;
}

}

}
close(DUPS);
