Hello, This is my very first post, I am using the "Learning Perl" book (7th eddition). I can't find a solution for my problem in this book, and googling has yield no results. I want to execute a particular function each time an iteration completes using the while loop: 

sub cp_domains {

    open(my $fh, $domainFile) or die "Coult not open file '$domainFile
+'";
        while (my $row = <$fh>) {
            chomp $row;
            my @domain = split /:/, $row;
            resolve_domain($domain[0]);
    }
    #close($fh);
}

The first time the “while” loop iterates it would correctly execute the function, but subsequent times is not returning anything. Can anyone provide me with some guidance?
