“LPI Linux Certification in a Nutshell” by Jeffrey Dean

I bought this book some time ago to try and improve my skills in the aim of applying for LPI Level 1 tests. This is a short yet very exhaustive guide for this certification, but is also very useful for everyone wishing to improve his knowledge of GNU/Linux basics.

All the topics are covered in this book (bash, file systems, networking, package management etc.).

Many people report having passed the LPIC tests thanks to this book and its sample exams.

The book is published by O’Reilly & Associates.
