Thanks everyone that helped me to get this done. I was finally able to do the shared word count on my own! Thanks again for all your time and help! And apl Trivial is a very relative term!!! I spent 20 hours to get the counting piece done. :) 
$filename = "tryit.txt";
open(IN, $filename) || die;
open(OUT, ">test1.csv") || die;
open(OUT1, ">test2.csv") || die;

my %freqs;
my $story; # Current story name 
  
while (<IN>) {
    if (/^\<(.*)\>\s*$/) {
        $story = ucfirst $1; 
        die "Duplicate story title: $story" if exists $freqs{$story};
        next;
    }
    
    next unless defined $story; # wait until we have a story title
s/[\.,:;\?"!\(\)\[\]\{\}(--)_]//g;
        
for my $word (/\w+/g) {
