Editorial Reviews

This outstanding book … gives the reader robust concepts and implementable knowledge of this environment. Graphical user interface (GUI)-based users and developers do not get short shrift, despite the command-line interface’s (CLI) full-power treatment. … Every programmer should read the introduction’s Unix/Linux philosophy section. … This authoritative and exceptionally well-constructed book has my highest recommendation. It will repay careful and recursive study.
Computing Reviews, August 2011

Designed as a primer for the popular Linux family of operating systems, this volume walks the reader quickly but clearly through basic operations and on into more advanced core concepts necessary for a deeper understanding of this open source software environment. Appropriate as a textbook for programmers or intermediate computer science students with a solid working knowledge of computer operating systems, the work provides some step-by-step instructions but focuses more on delivering conceptual understanding of the meaning and usage of commands and procedures for common Linux computing tasks. Each chapter in this volume provides illustrations, code examples, a concept summary and a collection of study exercises. Access to a companion website containing appendices and sample programs is included.
