Something like:
foreach (keys %hash1) {
next if $hash1{$_} eq $hash2{$_};
print $hash1{$_} $hash2{$_}\n;
}

Something like:
foreach (keys %hash1
';
This sets hash1's value at key '2' to 'foobar'.
Or am I misunderstanding your question?

not

You can also use a CPAN module, e.g.
use Data::Compare;
if (Compare(\%hash1, \%hash2)) {
# hashes are equal
} else {
# they arent
}
