Thanks for your reply. I know it is an FAQ, That's where I got the Fisher Yates option from, But unable to correctly implement it in my code..

If I try the list util it doesnt work... My code looks like this 

print "enter sequence and signal end with enter followed by ctrl d\n";
$sequence = <STDIN>;
chomp $sequence;
print "sequence inserted : $sequence\n";
@trips = unpack("a3" x (length($sequence)-2), $sequence);
@trips = join(" ", @trips);
 use List::Util 'shuffle';
@shuffled = shuffle(@trips);
print "@shuffled\n";

What is wrong/missing here?

I am incapable of installing the list::utils, I wouldn't know where to unpack them and how to properly install and run them. Do they need to be situated somewhere. I am on perl v5.18.2, so the list utils should already be there you mention?

How would I implement the fisher Yates algorithm correctly?
