The GNU Core Utilities or coreutils is a package of software containing implementations for many of the basic tools, such as cat, ls, and rm, which are used on Unix-like operating systems.
One of the other utilities included with coreutils is tac. It concatenates and prints files in reverse.
tac is the reverse of cat.
We can pipe the output of tac to tac to reproduce what cat does. $ tac / file | tac
This is free and open source software.
