To iterate over a hash, you want to use the keys() function.
foreach my $keys ( keys %table) {
print $table{$keys}->{search},"\n";
print $table{$keys}->{shortname},"\n";
}
Otherwise, perl iterates alternatively over the keys and the values of
the hash, which causes the extra newlines and the warnings.
