It sounds as if you want to count each print operation. You can do
that if you set a variable to zero before you begin printing:

my $lines = 0;

Then, each time you print a line, you add one to $lines.

print "whatever\n";
$lines++; # add one to $lines

After you've finished printing, $lines will hold the value you need. Is that it?

Cheers!
