> You can apply array_diff function on the sorted and unsorted file and check the output file to see weather sort had done any modification or not.

Unlikely, please demonstrate an example of how you intend to do it with Array::Utils

I mean real code!

update

as expected, pure nonsense!

  DB<110> use Array::Utils qw(:all)

  DB<111> @a = (8..12); @b = sort @a; @c = (@b,42)
 => (10, 11, 12, 8, 9, 42)

  DB<112> array_diff @a,@b

  DB<113> array_diff @a,@c
 => 42
