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.
