This guide stems from the notes I have been taking while working as a Linux sysadmin and while preparing the certification exams LPIC-1 (Linux Professional Institute Certification level 1), LPIC-2, and RHCSA (Red Hat Certified System Administrator). This document was originally named Linux & LPIC Quick Reference Guide, then I changed its title to be more certification-agnostic. This guide contains a good amount of topics for these certification exams, with some subjects handled in more details than others, plus other information about standards and useful tools for Linux system administration. I started writing this document in 2013 and it is my aim to update and integrate it periodically.
This is an independent publication and is not affiliated with, authorized by, sponsored by, or otherwise approved by LPI or Red Hat. You can freely use and share this whole guide or the single pages, either in electronic or in printed form, provided that you distribute them unmodified and not-for-profit. Please feel free to contact me if you find any error so I can correct it in future editions. Happy Linux hacking, Daniele Raffo

Ever wondered why Linux is lin ux ? It's because Linux is based on UNIX which was created in the late 1960's by Bell Laboratories and thanks to Linux is still the worlds most dominant operating system paradigm.
AT&T Archives: The UNIX Operating System
Made in 1982 this video is a really interesting way to learn about why Unix, (and now Linux) works the way it works. Pay special attention to the discussion on the kernel, shell and pipes. Enjoy the 1980's beards too! And should you want to see a modern discussion on the same pipes topic from the same man some 33 years later, then have a look at this interview with Professor Brian Kernighan
Nick Gonella introduces UNIX beginning with the history of UNIX, what distinguishes the UNIX system structure, and discussing the philosophy of UNIX.
