This is a collection of websites, online video courses and free eBooks. 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.
