Linux File Remove Command And Recovery
======================================

Motivation:
Since using an Ubuntu 12.04 server for the last couple years, I had not once erroneously
keystroked a faulty rm command. As a Linux users knows, the rm commands is used to remove a file or directory.
Futhermore, like most Linux commands various options can be added, such as: -r, -f, -i, etc. 
While not pertinent to the discusion, I will define these quickly for the inquisitve reader: 
   
   1. -r recursively delete directory and child files/directories.
