If you're printing out the lines, but they aren't printing as you would like, your problem is probably that you're printing plain text but your browser is expecting HTML. This suggests two solutions:

1. tell your browser to expect plain text, or
2. have your script print valid HTML.

It's probably easier to accomplish 1 than 2: just change the string "Content-type: text/html\n\n" to "Content-type: text-plain\n\n" and you should get a readable, if boring, output. If you want to output HTML, you should look at using CGI.pm, which makes it fairly easy to do such things.
