There is no doubt that 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 a service.
That's why it's very important for any programmer, IT professional, or a developer to learn and understand Linux, both the operating system, as well as command line.
Linux is 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 shell scripts, but also it is essential for many IT jobs like support engineers, testers, developers, business analyst, system admins, and even project/product managers
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. 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.
