That's because when you read from the file handle using the <> brackets, it doesn't automatically put the line into $_. You're just throwing away the result. print() does print $_, but in this case there's nothing in it. BTW, my personal advice would be to avoid the implied $_ magick until you are very familiar with Perl. I mean, there's nothing wrong with small code, but you should start by spelling everything out explicitly and then start using the shortcuts if/when they make more sense and actually give you a benefit.

Also, print; (without args) prints the content of $_ .
