A scientist by the name Linus Torvalds discovered the Linux operating system when he was a computer science student. He thought the Unix operating system needed improvements while he was working on the Unix operating system, but the designers of Unix rejected his suggestions, and this led to the development of a Linux operating system that allows changes and modifications to be done by the users.
The main reasons to study Linux are:

echo "Hello World!"
The prerequisites to learn Linux is a strong foundation of C programming language, basics on the operation of the operating system, and knowledge of computer organization and architecture. To learn about Linux-based operating systems, getting started with an easy-to-use operating system like Ubuntu is recommended. But after installing, learn how to use the terminal and get familiar with the User interface. Soon update Arch Linux or Gentoo to know the internal working.
Beginners can refer to this tutorial to understand the basics of Linux, the necessity to learn Linux, applications of Linux, examples of Linux, and the prerequisites to learn Linux. This tutorial is helpful for people who want to pursue a career in the field of Linux. This tutorial is good learning for all other readers.
