What is UNIX, and why is it Important?#

UNIX is a common operating system developed at Bell Labs research center. It aims to be a multi-user system that can multitask more efficiently than previous systems. Many modern operating systems such as Mac OSX, Linux (e.g., Ubuntu), and many others are UNIX-like in the way they designed their filesystems.

The principal user-end differences between UNIX and other operating systems are the interface by which one interacts with the filesystem and how filesystems interplay with networks.

In this part, we will talk about unix command line, gnu core tools, and other tools such as git to manipulate the filesystem.
