Linux Guide

This is a 300-page technical guide stemming from the notes I have been taking while studying and working with Linux. It is structured as a bundle of Linux quick reference sheets aka "cheat" sheets.

The guide lists more than 1200 Linux commands and contains useful information about standards and tools for Linux system administration, as well as a good amount of topics from the certification exams LPIC-1 (Linux Professional Institute Certification level 1), LPIC-2 (Linux Professional Institute Certification level 2), RHCSA (Red Hat Certified System Administrator), RHCE (Red Hat Certified Engineer), and CEH (Certified Ethical Hacker). This is an independent publication and is not affiliated with LPI, Red Hat, EC-Council, or any other organization.
You are free to share any single sheet, or also the whole guide in its entirety, provided that you distribute it unmodified and not for profit.

Download the guide from here (this is a permalink that always points to the latest edition). I release a new edition once a year.
