Linux continues to evolve. Today, it’s the world’s dominant Internet server platform. Google runs on Linux. So does Amazon -- including its market-leading EC2 cloud-based platform. It’s no wonder more and more system administrators and web developers need to be fluent in Linux. But fluency means knowing how to operate a Linux system from the command line, not from a pre-programmed GUI: that’s the only way to gain full control. Through three previous editions, Mark Sobell’s A Practical Guide to Linux Commands, Editors, and Shell Programming has earned a global reputation as the best way to gain this mastery. Now, Sobell and top Linux expert Matthew Helmke have thoroughly updated this best-seller to reflect Linux’s latest innovations.   Like all previous editions, A Practical Guide to Linux Commands, Editors, and Shell Programming, 4th Edition is fully distribution agnostic: it will serve you just as well, whether you work with Ubuntu, Fedora, Red Hat, or any other distribution. Sobell’s style is famously compact, concise, and comprehensive. He lives Linux, understands exactly what system features Linux professionals really need to master, and what examples can help them understand it quickly and in depth. This edition’s extensive new coverage includes the latest distributions, as well as DNF, Python 3, the zsh shell, Maria DB, and more.
