Brief: In this article, I’ll share with you the best resource to learn Linux for free. This is a collection of websites, online video courses and free eBooks.

How to learn Linux?

This is perhaps the most commonly asked question in our Facebook group for Linux users.

The answer to this simple looking question ‘how to learn Linux’ is not at all simple.

Problem is that different people have different meanings of learning Linux.

If someone has never used Linux, be it command line or desktop version, that person might be just wondering to know more about it.

If someone uses Windows as the desktop but have to use Linux command line at work, that person might be interested in learning Linux commands.

If someone has been using Linux for sometimes and is aware of the basics but he/she might want to go to the next level.

If someone is just interested in getting your way around a specific Linux distribution.

If someone is trying to improve or learn Bash scripting which is almost synonymous with Linux command line.

If someone is willing to make a career as a Linux SysAdmin or trying to improve his/her sysadmin skills.

You see, the answer to “how do I learn Linux” depends on what kind of Linux knowledge you are seeking. And for this purpose, I have collected a bunch of free Linux resources that you could use for learning Linux.

These free resources include eBooks, video courses, websites etc. And these are divided into sub-categories so that you can easily find what you are looking for when you seek to learn Linux.

If you are looking to build a career as a Linux SysAdmin, I recommend getting professional certification from The Linux Foundation, the organization that employs Linux creator Linus Torvalds. You can also check some inexpensive Linux courses on Udemy.

Again, there is no best way to learn Linux. It totally up to you how you go about learning Linux, by online web portals, downloaded eBooks, video courses or something else.
