below is a question i need help addressing. the script works in the way i want it to. i just need help finishing it. my script takes one file and creates a hash from it and then takes the second file and creates a key from it. the last part is suppose to take the keys that are the same and print out the corresponding value along with the key from the first file. I can get the key but not the value

heres and example of the data.

file 1

name1 ABCD

name2 BCD

name3 ASCDA

name4 AAAAA

file 2

name1 0.2

name5 0.3

name4 0.0002

name7 0.222

 my %s;

open(FILE1, $ARGV[0]) or die "Cannot open the file: $!";
my $hash_key;
my $hash_value;
while (my $line = <FILE1>) {
    if ($line =~ /^>(\S+)/) {
        $hash_key = $1;
    }
    elsif ($line =~ /\S/) {
        chomp $line;
        $hash_value = $line;
        $s{$hash_key} = $hash_value;

    } 
}
foreach my $hash_key1 (keys %s) {
    print "$hash_key1\t$s{$hash_key1}\n";
}

my %n;

open(FILE2, $ARGV[1]) or die "Cannot open the file: $!";
my $hash_key2;
my $hash_value2;
while (my $line2 = <FILE2>) {
    if ($line2 =~ /(\S*)/) {
        $hash_key2 = $1;
        $hash_value2 = $line2;
        $n{$hash_key2} = $hash_value2;
    }
    elsif ($line2 =~ /\S/) {
        chomp $line2;
    } 
}
foreach my $hash_key3 (keys %n) {        
        print "$hash_key3\n";
    }

my @n = ();
foreach (keys %n) {
    push(@n, $_) if exists $s{$_};
#this is where i am having trouble. tried using dumper and #grep didnt
+ help    
    print "$_\n";
}
close FILE1;
close FILE2;
exit;
