found it

i found what i was looking for in my perl cookbook (p. 7.:

open (OLD, "< $file");
open (NEW, "> $tempfile");
while (<OLD>) {
	$_ =~ s/\n/\r\n/sg;
	print NEW $_;
}
close(OLD);
close(NEW);

that's what i love in perl: it's such a tiny piece of code...

seems reasonable.
BUT: how do i read only one line of the file?

It's been a while since I did any Perl..

Make a copy of the file.
Open the copy.
Open the original.
FOR LOOP
-Read line from copy.
-Make changes.
-Wite line to original.
END LOOP
Close the original.
Close the copy.
Delete the copy.
