all that code can be replaced with this one line:
$hash_val{$dom}++ ;

You probably meant:
next if /^\s*$/; # skip blank lines

Hi All
Have a question, is it good coding practice to use a when calling a
subroutine, or it is not required, or it doesn't matter?
eg:
sub name {
some code here, returning a single value
return 0;
}
name();
cheers

It's good practice not to use it unless you understand exactly why you
would need to use it.
