The Linux operating system powers millions of web servers, data centers, and application platforms worldwide. Whether you're pushing applications to a cloud system like AWS, building a twitter bot on a Raspberry Pi, or rescuing files from a crashed laptop, Linux is required knowledge. The good news is that the same Linux command set will work for you no matter where you're using it. The better news is that Linux skills have staying power, so what you learn about Linux now will probably still work in a decade or two. Bottom line? If you're a developer, administrator, or just a weekend hacker, you need to know your way around the Linux command line. Let's get started!

"It's the best book for anyone that likes to learn more Linux and manage it."

~ Mohsen Mostafa Jokar

"Clinton's book is exceptionally clear, organized and concise. Learning any computer-related skill is always a matter of the chicken or the egg. Clinton takes a gentle approach to introducing you to the Linux 'chicken' by showing you how the egg is assembled."

~ Jonas M
