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

Before digging in further, let's discuss a few concepts which a programmer must be familiar with. 

This lesson is entirely dedicate to links but to understand links, you must have an idea of what an inode means. An *inode* is basically a link that points to the actual content or data. A file in the file system actually points to this inode instead of pointing directly to data.

# <mark> What are Symbolic Links? </mark>

Just like there are *shortcuts* in Windows and *alias* in Mac, symbolic links (aka Soft Link) is a file referring to another file. You can think of it as a pointer pointing to a another memory location just like in C++. If you delete the link, it will not affect the original file. 

>#### Note:
> The symbolic link of a file will not work anymore, and hence become a "dangling" link if you move that file to another location. 


In Linux, you can create a soft link using `ln` command.
