Are you saying that you have a reference to the hash itself, or a
reference to the scalar element stored in the hash? See below:
my %hash = ( SHELL => '/bin/csh' );
my $rh_hash = \%hash;
my $rs_element = \($hash{SHELL});
print $hash{SHELL}, "\n";
$rh_hash->{SHELL} = 'blog';
print $hash{SHELL}, "\n";
$$rs_element = 'wurzle';
print $hash{SHELL}, "\n";
Outputs:
/bin/csh
blog
wurzle
