What Is Linux?
Linux is an open-source operating software similar to UNIX but later evolved to become compatible with various types of hardware. Unlike other operating systems, it has gained a reputation for being highly customizable and community-driven.
Before we go any further, let’s get a good understanding of its main components:
- A kernel is a computer program that acts as the core of any OS. It manages the system’s resources and communicates with the hardware.
- System user space refers to all the code that operates outside the OS kernel. This administrative layer focuses on the execution of tasks such as software configuration and installation. It also includes the command line or shell and daemons. These processes run in the background and interact with the desktop commands.
- Applications are software that helps users execute tasks. They include everything from desktop tools to programming languages and multi-user business suites.
Since Linux is free and open-source, it has become one of the most popular operating systems in the world. It can serve as the basis for any IT initiative, such as cloud-based applications, containers, and security applications.
This OS is vital to information technology, finance, and communication industries. Examples are Wikipedia, the New York Stock Exchange, and the Android OS for mobile devices. Linux has become the preferred OS of governments and the military.
Moreover, Linux has gradually become the de facto operating system for executing reliable and critical data workloads for cloud employments and data centers. The software has multiple use cases, ranging from distributions, target systems, capabilities, and devices.
Today, Microsoft, Amazon Web Services, and Google Cloud Platform distribute Linux on publicly available systems.
Why Should You Learn Linux
Simply put, Linux is predicted to be the operating system of the near future, with an increasing number of systems and companies jumping on the bandwagon due to Linux’s versatility and stability.
Let us look at more reasons why you should be mastering this powerhouse of an OS.
Popularity
Linux is the darling of the IT industry, thanks to its servers that can execute almost any major programming language. It offers unrivaled affordability - you can’t beat open-source code and free servers—no wonder the market share of Linux continues to increase.
Strong Protection
Installing Linux on a PC or laptop can be time-consuming for novice users. However, Linux software compensates by providing you with all-around security protection against viruses and malware. It is also more stable than the Windows platform, with a design that prevents any third-party apps from changing or deleting data on your system.
High Stability
The Linux operating system is prized for its stability. With this OS, your system performs at the same speed for an extended period. It will not slow down or deteriorate as time passes.
Users of other operating systems often complain of having to delete and reinstall the software at regular intervals. They also experience frequent system crashes or software installation updates. If you are using Linux, these are all behind you.
Plus, the uptime for Linux-based servers is relatively high as compared with servers operating on other systems. Also, they do not require rebooting whenever a patch or software update is needed.
Compatible With Most Hardware
Here’s a reality faced by tech users. Each time a newer version of an operating system or software is released, the previous version becomes obsolete and redundant. This means the technical specifications on your PC or laptop are no longer compatible with these releases.
That’s not an issue with Linux. It does not require users to be equipped with the latest hardware models, as this OS can also run on old or obsolete hardware systems. A user can choose from the different modules Linux offers during the installation process.
Open-Source Software
Since the Linux operating system falls under the Free and Open Source Software (FOSS) category, its code is universally available to all users. They can build or create something new using the Linux platform without worrying about copyright or permissions. Due to this feature, multiple versions of the OS have been worldwide.
Who Can Learn Linux?
Anyone can learn Linux, provided you have some tech background. The key is to understand the basic commands and syntax of this OS. There are plenty of online courses to choose from. Expect that it may take up to 18 months to acquire this new tech skill. Mastery will come in time as you gain experience in using this OS.
Learning Linux benefits those who want to learn to program for professional reasons. If you wish to switch careers or develop a new skill, nothing stops you.
If you are already a programmer or developer, there’s a high probability that you may encounter or need to work on Linux-based projects. Getting a jump start on it will give you a competitive edge over others in your field.
It is said to be one of the most accessible platforms to start with if you want to build a cybersecurity career. Creating and executing security-based applications is quite convenient on a Linux platform compared to other operating systems.
Can I teach myself Linux?
Yes, it is possible to teach yourself Linux. Linux is an open-source operating system, meaning the source code is available for anyone to access and modify. There is a vast community of Linux users who are willing to share their knowledge and resources with others, making it relatively easy to learn.
One of the best ways to start learning Linux is to install it on your computer and experiment with it. Many distributions of Linux, such as Ubuntu and Fedora, have user-friendly installation processes and graphical interfaces that make it easy for beginners to get started. You can also find a wealth of online resources, including tutorials, forums, and documentation, that can guide you through the learning process. With practice and persistence, you can gain proficiency in Linux and even advance to more complex tasks like system administration and software development.

Master Linux commands in 10 easy steps
Linux commands can seem intimidating for beginners, but with a bit of practice and the right resources, you can master them quickly. Here are ten easy steps to help you become proficient with Linux commands.
- Learn the basic commands. Before you can start using Linux commands, it's essential to know the basics. Some of the most important commands to learn include "ls" (list files and directories), "cd" (change directories), and "pwd" (print working directory).
- Understand the file system hierarchy. In Linux, files and directories are organized in a hierarchical structure. Knowing how this structure works will help you navigate the file system more efficiently.
- Get familiar with the command line interface. The command line interface (CLI) is the primary way to interact with Linux. Understanding how it works and how to use it effectively is essential.
- Practice using commands. The best way to become proficient with Linux commands is to practice using them. Try running different commands and see what happens.
- Learn how to use wildcards. Wildcards are a powerful tool that allows you to work with multiple files simultaneously. For example, the command "ls *" will list all files in a directory.
- Learn how to use command options. Most Linux commands have options that can be used to modify their behavior. For example, the command "ls -l" will display the files and directories in a directory in long format.
- Learn how to use command arguments. Arguments are used to specify the target of a command. For example, the command "cd /usr" will change the current directory to /usr.
- Learn how to redirect output. Redirection allows you to redirect the output of a command to a file or another command. For example, the command "ls > file.txt" will redirect the output of the "ls" command to a file called "file.txt".
- Learn how to use pipes. Pipes allow you to connect one command's output to another command's input. For example, the command "ls | grep file" will list all files in a directory and search for the word "file".
- Keep learning. Linux commands are vast and complex, but with practice and persistence, you can become proficient with them. Keep learning new commands and experimenting with different options and arguments.
By following these steps and practicing regularly, you'll be able to master Linux commands in no time. Remember to be patient with yourself, and don't be afraid to ask for help if needed. Happy Learning!
