pr09 has asked for the wisdom of the Perl Monks concerning the following question:

Hi All, I am back with one more question. Please note that i am not asking for any ready made code here but just a few tips from the experts present here. So no cheating on my part,if anyone can offer help i will be thankful. As i am learning perl since 1 week now,so i have a question. I am writing into a file some values and am splitting it to get the second position say $F2. Now i want to print and sort the unique values of that field only. I don't care about the rest of the fields in my file. Just i want to print the $F2 in a unique and sorted manner.
