How to unpack uncompressed files

All (Up to date) Real Operating Systems

Most operating systems, will already recognize the *.zip and *.tar.bz2 files as a compressed files, and doing something as simple as pressing the left button over the file, and selecting the "Extract..." or similar option.

Also if you want to do with a command, and you OS has a bash compatible shell, then just type this:

Bourne Shell
 
$tar xvjf package.tar.bz2

The other

If you have that other thing, I don't know, I wish you luck.
