in reply to Alphabetical order with .txt file

Like grep says: use strict; use warnings;

That won't catch your problem though. You're adding a space with @list1[$nk] = "$item1 \n";. Try dropping the space before the newline.

Other concerns:

  • @list1[$nk] is better written as $list1[$nk] ; Though just until Perl 6
  • You currently read the file
    Then sort (though it's not shown)
    write the file
    read it
    and then display it
  • Try reading it
    sorting it
    displaying it and writing it at the same time
  • IIRC, $#list1 notation is being dropped. Just go ahead and use @list1 for # of elements. scalar @list1 is you need to.
  • Another version of your code is in my pad
    I'll leave that there for your review for now

Update: boo has an excellent point. I just glossed by that point.
