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

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 runs on Windows as service. If you take out standalone apps like IDEs or tools, most of the real world Java applications run on Linux e.g. payment gateways, trading systems, and other financial applications. That's why it's very important for any programmer, IT professional, or a developer to learn and understand Linux, both operating system, as well as command line.

Linux as one of the most important skill 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 e.g. 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 an application which runs on Linux. It also separates a good programmer from an average one. A good programmer is often good on 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. 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 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 course down there but still, you can use them to start your Linux journey.

5 Online Training Courses to Learn Linux

If you have been here before then you might be familiar with my 3 point formula to learn a 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 e.g. writing a shell script or something to take your knowledge to next level.

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