hopefully, I formatted this correctly. stuck while reading in the second keys and values of 2nd file and checking against the existing hash key and value can you help debug this piece? 

 
uno = uno 
due = dos 
tre = tres 
quattro = quatro 
cinque = cinco

use strict; 
use warnings; 

use Data::Dump qw(dump); 
use Storable; #don't know how to use this to test yet. 

my %hash; open my $in, '<',"./test_data.txt" or die "can't open the fi
+le:$!\n"; 

while (<$in>){ 
  chomp; 
  my ($key, $value)= split (/\s*=\s/); 
  $hash{$key}=$value;  #it's clear to me now
  } 
close $in; 

#will check against %hash with new keys and values  

#opening files for read and write
open my $in2,'<',"./test_data2.txt" or die "can't open file : $!\n"; 
open my $out ,'>' ,"./test_data_out.txt" or die "can't open the file f
+or write:$!\n"; 

while (<$in2>){ 
  chomp; 
  my ($key,$value) = split (/\s*=\s/); #splits row into 2 col  
  if exists $hash{$keys}{ 
      dump $out \%hash; 
   } 
}
