Gain insights into the power of the command line. Learn about Linux BASH through theoretical and practical exercises, mastering essential concepts and commands for efficient programming.

Ever wondered why command line is still in use even when there are hundreds of human-friendly GUI’s and tools available? Everyone in the programmer's world would agree on one thing: Command Line is far more powerful than any GUI. It provides a richer experience in terms of speed and expressiveness.

For beginners, it might be hard to appreciate its beauty and a little challenging to shift from an interactive interface to a blank box with just a “$” sign showing that keeps prompting the user to enter complex commands if you want to get something done. This is why we felt the need to build a course which could help the user overcome his/her fear of using the terminal (we have all been there).

The objective of this course is to help you get a strong grip over Linux, mainly focusing on BASH. You will be covering both, the theoretical and practical sides. First, you will learn a bunch of concepts necessary to understand things and then study some nifty commands to get useful things done out of them.

Bash for Programmers

## What is the Command Line?
>A *command-line interface* (CLI) or a command line interpreter or shell is simply a mean for the user to interact with the system in the form of progressive and sequential commands. 

$$$$
A useful way for the users to conduct various actions like viewing, handling, and manipulating files on the computer is *Graphical-User-Interface* or GUI. However, CLI is the primary approach to interact with the computer.

CLI has essential *advantages*, especially for meticulous computer users. It lets you more control over your system by allowing you to run system commands and automate your various tasks. Similarly, you can add modifiers to define exactly how you want your program to execute.

### Types
"Shells" have evolved through quite a many adaptations. In *OS X* and *Linux*, most commonly used shell is `bash`, whereas in *Windows* has `MS-DOS` based CLI.
