flip is a Perl script that reverses the text in a given file line-by-line. That is, the first line in the file switches position with the last, the second line in the file switches with the next-to-last, and so on

flip IS LIKE tail -r, BUT IT HANDLES MUCH BIGGER FILES

gnu tail don't have -r /bin/tail does

gnu, use tac instead.
