You want to print matching values and the first key? The shared/matching keys will be identical, so the key becomes ambiguous.. Try the following code. It uses anonymous hashes and a subroutine.

use strict;
use warnings;
use Data::Dumper;

my $hash1 = {qw/
name1 ABCD
name2 BCD
name3 ASCDA
name4 AAAAA
/};

my $hash2 = {qw/
name1 0.2
name5 0.3
name4 0.0002
name7 0.222
/};

my $hash_result = sub{
    my ($hash1,$hash2) = @_;
    foreach my $key (sort keys $hash1){
        print "\'hash1 value: $hash1->{$key}\' AND \'hash2 value: $has
+h2->{$key}\' AND shared key: \'$key\'\n" if(defined($hash2->{$key}));
    }
};

$hash_result->($hash1, $hash2);

My output:
rsx491@temple:~/Perl/test$ perl hash_compare.pl 'hash1 value: ABCD' AND 'hash2 value: 0.2' AND shared key: 'name1' 'hash1 value: AAAAA' AND 'hash2 value: 0.0002' AND shared key: 'name4'
