File 1 contains: name,metric1,metric2,metric3. File 2 contains: name,metric4. I have a script in place that will compare the two "names" and find a match. However, I also want to print metrics 1-4. Code looks like this:

 foreach $key (keys %hash1) {
   if (exists $hash2{$key}) {
     print "$key\n";
     }
   }

Am somewhat new to perl and can get syntax down to print the $key that is common to both files, but also want to print metrics 1-4 on each line. How to include metrics 1-4 on same line as $key Would appreciate any assistance.

here's all the code

$filename1 = shift;
$filename2 = shift;
open (IN1, "$filename1");
open (IN2, "$filename2");
%hash1;
%hash2;
@data1 = <IN1>;
foreach $line1 (@data1) {
    # print "$line1\n";
    chomp $line1;
        $line1 =~ /(.*?)\,(.*?)\,(.*?)\,(.*?)\,(.*?)\,(.*)/;
        $description1 = $1;
        $cktsizetemp1 = $2;
        $bits1 = $3; 
        # print "$3\n";
        $availability1 = sprintf("%.2f", $4);
        $bitsin1 = $5;
        $bitsout1 = $6;
        $description1 =~ /.*?\-(.*?)\-(S|G|SD|A|AD|FAA|SA).*?([A-Z|0-9
+][A-Z|0-9][A-Z|0-9][A-Z|0-9])$/;
        $devicename1 = "$1\-$2";
        $cd1 = $3;
        # print "$devicename1\n";
        $hash1{$devicename1} = "$devicename1";
        
    }
    
@data2 = <IN2>;
foreach $line2 (@data2) {
    # print "$line2\n";
    chomp $line2;
    $line2 =~ /(.*?)\,(.*)/;
        # print "$line2\n";
        $description2 = $1;
        # print "$description2\n";
        $cpu_util = $2;
        $description2 =~
/.*?\-(.*?)\-(S|G|SD|A|AD|FAA|SA).*?(.|:)/;
        # print "$description2\n";
        $devicename2 = "$1\-$2";
        $cd2 = $3;
        # print "$devicename2\n";
        $hash2{$devicename2} = "$devicename2";
    
    }    
#####good to here#####    

foreach $key (keys %hash1) {

    if (exists $hash2{$key}) {
