Hi to everyone. I have a text file, which contains list of couple of words, like this: 
 [Nn]ucle[oi]:[Pp]roton[oi]
OCS:chip
[Ff]otosistema:LHC
N2:[aA]zoto
[Cc]enobio:[Cc]appell[ae]
[Ee]sercit[oi]:[Ll]egion[ie]
[Tt]erreno:sabbia
[Ll]attosio:[Gg]lucosio
codice:lettera

I have to know how many times each word of the first column occurs in a text file I have.
I've tried to do this:
#!/usr/bin/perl
use strict;
use warnings;
open my $listaParole,"File_Input/Coppie_Parole.txt" or die;
 
my %hash;
while (my $line=<$listaParole>) {
chomp $line;
my ($word1, $word2) = split /:/, $line;

$hash{$word1} = $word2;
}

open my $testo, "<File_Input/Testo.txt";  
open my $conteggio, ">File_Output/Conteggio.txt";
my %arrayris;
my $indice=0;

    while (my $text=<$testo>){
     for my $key (keys %hash){
       my $value = $hash{$key};
       my $arrkey=$key." ";  
       my $count = 0;
       $count += () = /\b$key\b/ig while <>;
       print $conteggio "$arrkey) => $count\n";


      
}
}
close $testo;
close $conteggio;

but I'm not having any results!
What can I do?
Thanks for your help
