tac_revSometimes it would be useful to print file contents or output of previously executed command in reverse. There are two little utilities that are part of Linux coreutils: tac and rev.

TAC concatenates and prints files in reverse (last line first). REV reverses lines of a file: it copies the specified files to the standard output, reversing the order of characters in every line.
