Hello devs, have you ever wondered why the command line is still so popular even when there are hundreds of human-friendly GUIs and tools available? Everyone in the programmer's world would agree on one thing: Command-Line is far more powerful than any GUI. It provides a richer experience in terms of speed and expressiveness.
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 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 very important for any programmer, IT professional, or a developer to learn and understand Linux, both the operating system, as well as the command line.
Linux as 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 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 and paid Linux courses you can take online to learn Linux at your own pace and at your own time.
Some of 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.
Btw, if you don't mind paying few bucks for learning something as valuable as Linux then I also recommend you check out Learn Linux in 5 Days and Level Up Your Career course on Udemy. It's one of the most comprehensive course and you can get it on $10 on Udemy sales which happen every month.
10 Best Courses to learn Linux command line for Developers
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 to learn Linux in 2019.
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 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 its more suited for developers, QA, System admins, and programmers.
1. Introduction To Linux
This is a good introductory course on Linux which will tell you what is Linux, its history and what does different Linux Distributions means e.g. CentOS, RedHat, Fedora, Ubuntu, etc. Basically all the knowledge you need to learn the Linux commands.
Here is the link to join the course: Introduction to Linux
You will also learn how to set up your test lab to run the Linux commands using VirtualBox and CentOS.
Once you have got your setup, the course will then teach you basic Linux commands like how to create and move files and directories, how to archive and compress files, how to combine two or more commands using pipes, and how to redirect output to a file.
In short, a good introduction to Linux for beginners who are hearing Linux first time. After attending this course you will have enough passion to learn more about Linux and find out more about your favorite Linux distribution.
2. Linux Command Line Basics
This is an introductory course to the Linux command line. It's great for both Linux beginners and advanced Linux users.
If you are a beginner this is your course. You will learn the basic things about the command console in Linux. I did it because was asked in several interviews and I wanted to be more confident with it.
Also, you could do it using x2 speed. It will save you half of the time and you will be able to complete anyway without losing anything.

3. Vim Masterclass
Did you know that the most productive command line experts exploit the powerful features of the Vim text editor?
The problem is that if you want to get really good with Vim it can take you an extremely long time if you're trying to learn it on your own.
This course gives you the absolute shortest path to learning the basics. It also provides you the fastest way to learn the most advanced features, too.

4. Bash for Programmers
For beginners, it might be hard to appreciate its beauty and a little challenging to shift from an interactive interface to a blank box with just a "$" sign showing that keeps prompting the user to enter complex commands if you want to get something done.
This is why I am sharing this course that could help a junior developer fear of using the terminal (we have all been there). The objective of this course is to help you get a strong grip over Linux, mainly focusing on BASH.
You will learn both, the theoretical and practical sides. First, you will learn a bunch of concepts necessary to understand things and then study some nifty commands to get useful things done out of them.

This is a great course to purchase in $12 after discount but if you happen to like [Educative] as I did then it's better to get an Educative Subscription which provides access to their 100+ software courses. You will get better value.
5. Learn The Linux Command Line: Basic Commands (Free)
This is an awesome course to learn the Linux command line. As I have said before, the command line is an incredibly useful tool for developers and programmers.
If you want to get into Ruby on Rails, Django, Unix customization and so much more, learning the command line will help you immensely.
Here is the link to join the course: Learn the Linux Command Line: Basic Commands
In this course, you will learn most of the essential Linux commands related to file management, process management, system management, etc.
The command line course is mainly for Linux users but Mac users can also benefit though not everything is applicable to them.
For beginners, the command line may seem difficult and complex and it may be hard to sit down and learn on your own and that's where this course steps up. It will teach you how to use the command line and skip the boring, unnecessary stuff that you may never use.
6. Red Hat Enterprise Linux Technical Overview (Free)
This is a free Linux course from Red Hat itself. In this official Red Hat training course, Steve Bonneville, a technical curriculum architect for Red Hat Training, will teach you the basics of Linux and demonstrate basic practical techniques of Linux use and system administration tasks for IT professionals.

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.
Here is the link to join the course: Learn Linux on a Mac
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 and Private Clouds running on OpenStack.
So it will be really worth if you can get some basic experience on the Linux OS before you start working on Cloud servers.
