Here is one way: 
 
sub findcd {
    my $someref = shift;
    my $type = ref($someref);
    if( $type eq "" ) {
    # do nothing for non-references
    } elsif( $type eq "ARRAY" ) {
    foreach my $elem (@{$someref}) {
        findcd( $elem );
    }
    } elsif ($type eq "HASH" ) {
    foreach my $elem (keys %{$someref}) {
        print "cd: $$someref{$elem}\n" if $elem eq "cd";
        findcd( $$someref{$elem} );
    }
    } else {
    warn "Cannot deal with $type.\n";
    }
}

findcd( $p );

but I am sure there is a module doing it simpler.
