    Hi dee00zee,
    The my puts the variable into scope within the while loop.
    For information have a look at perldoc perlintro and the discussion on lexical scope.

    my is used to declare and assign the variable $line. If you would 'use strict;' this is a requirement for the script to run.

    Manual for my: http://www.perl.com/doc/manual/html/pod/perlfunc/my.html

    Edit: Excuse me for this post, I somehow missed that the question was already answered.
