5 Free Linux Courses for Programmers and IT Professionals to Learn Online [2022]

Linux is one of the most popular operating systems to run server-side applications. I have seen almost all Java applications running on Linux, barring a couple of them, which run on Windows as a service. If you take out standalone apps like IDEs or tools, most of the real-world Java applications run on Linux, like payment gateways, trading systems, and other financial applications. That’s why it’s essential for any programmer, IT professional, or developer to learn and understand Linux, both the operating system, as well as the command line.

Linux is also one of the most important skills because it serves you for a long time. It not only makes you productive and teaches a lot of automation by encouraging you to write scripts, but also it is essential for many IT jobs, like support engineers, testers, developers, and system admins.

It is also one of the essential tools for programmers without knowing Linux is difficult to find out what’s going on in an application that runs on Linux. It also separates a good programmer from an average one. A good programmer is often good at Linux commands as well.

If you want to learn Linux or UNIX, both operating system and command line, then you have come to the right place. Earlier, I have shared free bash scripting courses and In this article, I’ll share some of the free Linux courses you can take online to learn Linux at your own pace and at your own time.

These courses are free, but it doesn’t mean they are of inferior quality. They provide a nice overview of many essential Linux concepts, including the Linux command line and essential commands like find, grep, sed, curl, and chmod. Of course, they are not as comprehensive as some of the paid courses down there, but still, you can use them to start your Linux journey.

5 FREE Online Training Courses to Learn Linux

If you have been here before then, you might be familiar with my 3 point formula to learn new technology. In general, whenever I have to learn a new programming language, a framework, or a library, I do three things, first join an online course, second, buy a good book, and third, create a toy project to start with.

These 3 things have helped me to learn many useful tools, technologies, frameworks, and libraries, and I also suggest you follow these. In the past, I have shared some Linux command-line books, and Today I’ll share some of the free online training courses.

You can first take these courses and then read those books to learn and master Linux concepts. Once you have a good idea, you can start a project, like writing a shell script or something to take your knowledge to the next level.

This article contains courses to learn both Linux OS as well as the Linux command line, which is more important. Anyone who wants to learn Linux can use these free courses, but it’s more suited for developers, QA, System admins, and programmers.

1. Introduction To Linux

These practical tasks will help you to get going in Linux and give you the confidence to work in real servers.

5. Learn Linux on a MAC or Windows

If you want to learn the Linux command line but happen to work on Mac or Windows, then this is the perfect course for you. In this course, you will learn how you can set up an Ubuntu Linux server on VirtualBox to get a taste of the Linux command line on Mac or Windows itself.

This is the first step towards learning Linux commands, particularly if you do most of your work in Mac or Windows. Although it takes a lot of time to become an expert in the Linux command line, having a lab setup is the best way to try out those commands by yourself.

Also using a VM as a virtual box in Mac or Windows is a safe idea because you can easily delete it and start again if something goes wrong, and more importantly, you can work offline without an Internet connection.

In Today’s world, Linux is very widely used in Internet infrastructure powering Web servers, Public Cloud infrastructures like Amazon AWS, Microsoft Azure, and Private Clouds running on OpenStack. So it will be really worthwhile if you can get some basic experience on the Linux OS before you start working on Cloud servers.

That’s all about some of the free courses to Learn Linux online. As I have said before, Linux is a must-have skill for any programmer or IT professional. You can do a lot more if you know Linux. It also opens a door of opportunities because most of the real-world applications run on a Linux server. And the best part of learning the Linux concept is that it will serve you for a long time. It will not become obsolete as a framework or library will.
