Learning Linux: A Guide for Beginners (2024)

Linux is an operating system that has been around since the 1990s. It powers most modern technologies that we use today such as Android devices, televisions, cameras, and even smart appliances. This guide will show you how to learn Linux and the real-world applications of this open-source operating system.

Learning Linux is a great way to boost your resume as it is a must-have skill, especially if you are looking to explore a programming career. According to the Linux Foundation 2021 report, Linux is the second most sought-after skill by open source hiring managers. Let’s go over several tips that can help you learn Linux, even as a beginner.

What Is Linux?

Before we dive into the operating system, we should first understand what Linux is. It is a kernel upon which many operating systems, such as Ubuntu and Arch Linux, are built. It is open source which means you can read the code associated with the kernel. The Linux kernel was released in 1991 by Linus Torvalds.

Linux was designed as an updated version of the UNIX OS software, which Torvalds thought needed to be improved. After his suggestions were ignored, he decided to create his own operating system with all the features he needed. Over time, Linux has become ubiquitous and powers everything from modern phones to smart devices.

If you have ever wondered about the process that enables applications, websites, or games to run on your computer or smartphone, the answer is an operating system that allows you to use the hardware. Linux is just one example of today’s most popular operating systems.

Why Should You Learn Linux?

The answer to why you should learn Linux is that it is a must-know technology with a wide range of applications. It is used for embedded systems, mobile phones, and servers, among others. Even the Career Karma website is hosted on a Linux server.

Linux and its various versions are widely used in the technology industry. As such, some basic experience with Linux would let employers know that you are capable of navigating and customizing an open source operating system should they need it to solve a specific business problem. If you want to become a system administrator, knowing Linux is almost essential.

But, even if you’re not interested in systems administration, knowing Linux can still be helpful. With a working knowledge of Linux, you’ll be able to navigate the command line more effectively. This will assist you in a wide range of technical environments. You’ll also have a better understanding of how computers work.

How Long Does it Take to Learn Linux?

How long it takes to learn Linux depends on your intended purpose. You can expect to learn it within a few days if you use Linux as your main operating system. You will develop stronger Linux proficiency if you spend a couple of hours a day for a few weeks.

Learning how to use the Linux command line is a different story. Expect to spend a few weeks learning basic commands. Then, there is a whole world of more complex commands to master. Expect to spend around six months learning about more advanced commands and the system architecture.

It will take you a shorter period of time to learn Linux if you’ve already worked with a Linux system before. These include the Raspberry Pi and macOS, both of which are built upon Linux operating system distributions.

What Is Linux Used For?

If you’re wondering what Linux is used for, the simple answer is that it powers other operating systems and software. As an operating system, Linux can bridge the gap between regular programs, such as word processors, and the hardware that runs those programs. Its open-source nature allows you to use, modify, customize, and redistribute the source code for free.

There are also many Linux operating systems that work as desktop environments. Ubuntu is one example. These operating systems let you use Linux as an alternative to another system like Windows or macOS.

Other Linux operating systems are written for tinkering. The Raspberry Pi, for instance, uses Raspbian. It is used for embedded systems applications, robotics, and other computer engineering tasks. Linux even powers the Android operating system, with over two billion devices in the world. These examples barely scratch the surface of what you can do with Linux.

Is Linux Hard to Learn?

Linux is not hard to learn. The more experience you have using modern technology, the easier you’ll find it to master the basics of Linux. You can learn the basic Linux commands in a few days but it will likely take a few weeks to become more familiar with these commands. More advanced commands may take years for full mastery.

The Linux command line is known for the degree of customization it supports. As a result, you’ll find no shortage of unique combinations for commands and new distributions of Linux. But, you don’t need to know how to use all the advanced commands to build a good understanding of Linux.

If you come from using macOS, you’ll find it easier to learn Linux. This is because macOS is based on UNIX. UNIX incorporates many of the same principles as Linux. You’ll find cross-overs between these two technologies.

Linux is “Open Source.” What Does That Mean?

Linux is open source in that its source code can be publicly accessed. Linux was released under the GNU General Public License (GPL) which means anyone can run Linux for any purpose. This is one of the main reasons Linux has become so prominent.

Because Linux is open source, anyone can study how it works or create their own copy of a Linux system. The term “Linux” itself is trademarked by Torvalds and the source code for the main project is under copyright.

Shell Scripting

Bash, or shell, scripting allows you to automate similar tasks and batch together commands into a single file. Bash scripts execute in a Bash Linux terminal. Here are the main topics related to bash scripting that you should learn about:

• Creating a Bash file
• Variables
• Loops and conditionals
• Accepting user input

Users and Permissions

Linux offers a wide range of user and permission settings. These ensure that only the right users can access specific files and folders on a computer. Here are the main topics you should learn about when it comes to users and permissions:

• What is a user
• How to create a user
• What is a group
• How to create and update a group
• Read, write, and execute file permissions

These are just a glimpse into what you should study when learning Linux. The operating system is so advanced that we cannot possibly list everything you need to know in one article. The above topics constitute the bulk of working with Linux and learning them will give you a good sense of its fundamentals
