Ever thought of learning the Linux Operating System? Why do software and network engineers love Linux? why Linux is different from others. Well, why don’t you find yourself? In the next 30 days, you will learn Linux OS from scratch. Let’s get started.

In the world of operating systems, Linux stands out as a powerful, versatile, and open-source solution that has revolutionized how we interact with computers. Linux is a strong platform to build, develop, and innovate—not only for an established IT professional but also for a beginner. It’s a 30-day walk-through journey, understanding Linux step by step, from basic standard system commands to advanced system administration.

What is an Operating System?

The OS is software specifically designed to operate, control, and coordinate all the hardware and software resources available in the computer. It possesses a user interface for the management of tasks that can be done by end users—such as running applications, file management, and input/output management. The operating system, for example, is Windows, macOS, and Linux. The OS provides the foundation for ensuring that other programs, and especially different users, can effectively share the resources of a computer.

What is Linux?

Linux is a Unix-based, open-source operating system. Created by Linus Torvalds in 1991, Linux has grown to be a major force in the tech world: powering anything from smartphones and servers to supercomputers, including embedded systems. An open-source operating system is one whose source code is made available for viewing, modification, and distribution by anybody, hence, by implication, a collaborative and innovative community.

Why Linux?

• Open Source: Free to use and modify, promoting collaboration and innovations in the community.
• Security: Known for its robust security features and resistance to malware and viruses.
• Flexibility: It can be used for anything from a desktop to servers and also embedded systems.
• Performance: Efficient resource management, suitable for both high-performance computing and low-spec devices.
• Community Support: A very large, active community offering a lot of support and resources in terms of documentation and tools.

Over the next 30 days, you will delve into various aspects of Linux, starting from basic concepts to advanced topics, ensuring a solid foundation and practical skills.
