After reading the file line by line into an array called @LIST, you would then remove the duplicates like this:

my %seen;
grep !$seen{$_}++, @LIST;

and then sort the list by names:

sort {uc($a) cmp uc($b)} @LIST;

( Note: I copied the first code snippet from https://stackoverflow.com/questions/7651/how-do-i-remove-duplicate-items-from-an-array-in-perl )
