This is an easy way to get six random integer numbers between 1 and 49: 
$ perl -e 'print int (1 + rand 49), " ", for 1..6'
48 16 40 39 21 24

Adding 1 to the result of the rand function makes it sure that the obtained integers will be between 1 and 49 (and not between 0 and 48). It can even be made slightly simpler: 
$ perl -e 'print 1 + int rand 49, " ", for 1..6'
5 33 19 21 25 39

If you are under Windows, change quotes for apostrophes and vice-versa: 

perl -e "print 1 + int rand 49, ' ', for 1..6"

However, besides everything that has already been said, this still suffers from a major drawback if you're going to use it for picking up lotto numbers: there is no guarantee that you don't get twice the same number. I only had to run the first Perl one-liner above 9 times to get the following result: 
$ perl -e 'print int (1 + rand 49), " ", for 1..6'
20 32 37 32 3 39

where number 32 appears twice, which is not good for lotto numbers. Since this looks a bit like a homework assignment, I'll leave it to you to find out how to make an additional draw if you find a number that has already been picked up.

A final additional advice: don't comment out use strict;, rather solve the problems that it diagnoses (hint: use my to declare your variables).
