Explanation

Sorting lines is easy: everybody knows the sort command.

But what if you want to do the other way around? The above perl one-liner does just that:

  • -MList::Util=shuffle load the shuffle function from the List::Util package
  • -e '...' execute Perl command
  • print shuffle <> call List::Util::shuffle for the lines coming from standard input, read by <>
