Read on if you want to learn to use Linux and level up your career but are pressed for time. As the Linux Training Academy founder and an instructor of several courses, I've had the good fortune of helping thousands of people hone their Linux skills. Interacting with so many people just getting started with the Linux operating system has given me invaluable insight into the particular struggles and challenges people face at this stage. One of the biggest challenges for people interested in learning the ins and outs of Linux is simply a lack of time. When working with a limited and extremely valuable resource, you want to make the most of it. The next biggest challenge for Linux newcomers is knowing where to start. There is so much information available that deciding what to focus your attention on first is a big enough hurdle to keep many people from even starting. What's worse is starting to learn only to discover too many concepts, commands, and nuances that aren't explained. This experience is frustrating and leaves you with more questions than answers. That's why I've written this book. Not only have I condensed the most important material into five sections, each designed to be consumed in a day, but I've also structured the content logically and systematically. This way, you'll make the most of your time by learning the foundational aspects of Linux first and then building upon that foundation each day. In Linux in 3 Days, you will learn the most important concepts and commands and be guided through several practical and real-world examples. As new concepts, commands, or jargon are encountered, they are explained in plain language, making it easy to understand. Here is what you will learn by reading Linux in 3 Days: How to get access to a Linux server if you don't already. What a Linux distribution is, and which one to choose? What software is needed to connect to Linux from Mac and Windows computers? Screenshots included. What SSH is and how to use it, including creating and using SSH keys. The file system layout of Linux systems and where to find programs, configurations, and documentation. The basic Linux commands you'll use most often.

What you learn in Learn Linux in 5 Days applies to any Linux environment, including Ubuntu, Debian, Linux Mint, RedHat, Fedora, OpenSUSE, Slackware, and more.
