The only authorized textbook for the UNIX curriculum of the Cisco Networking Academy Program

With the Fundamentals of UNIX Companion Guide, you can access this information for reference, study, and review at any time:

  • Each chapter has a "Key Terms" section plus a list of commands and utilities introduced for focused study.
  • The Class file system tree structure (in the inside-front cover) uses a graphical hierarchy to show all directories and files.
  • A UNIX command summary (in the inside-back cover) lists all commands in the book grouped by function and indicates the chapter number where they are introduced.
  • Includes a complete quick reference of all UNIX commands used in the book and course providing definitions and examples of use, plus a commonly used vi editor command reference.
  • Throughout this book, you see references to the lab activities found in the course and compiled in the Cisco Networking Academy Program Fundamentals of UNIX Lab Companion, Second Edition. These labs allow you to connect theory with practice.
  • New information on Linux certification options. These include proprietary certifications such as Red Hat and the more industry-neutral CompTIA Linux+ certification.

This Cisco authorized textbook is a portable desk reference designed to complement the Sun Microsystems sponsored Fundamentals of UNIX online course in the Cisco Networking Academy Program that focuses on Solaris and Linux. The Fundamentals of UNIX Companion Guide, Second Edition, contains the information from the online course with additional in-depth content to enhance your understanding of some topics plus supplemental aids to assist in studying.

In the Fundamentals of UNIX course, you are introduced to essential UNIX topics, system administration, and certification options. You learn UNIX command-line utilities as well as the Common Desktop Environment (CDE) and GNOME graphical user interfaces. The entire course provides you with a strong foundation in most varieties of UNIX, including Sun's Solaris and Linux, and prepares you to move on to more advanced courses in UNIX system administration.

This second edition of the Companion Guide includes general Linux characteristics and new generic UNIX information on subjects such as the Emacs editor, working with disks and CD-ROMs, advanced string searching, and Bash shell features and customization. The material covers some of the basic objectives of the CompTIA Linux+ certification exam. The remaining objectives are covered in the IT Essentials II: Network Operating Systems Networking Academy course and Companion Guide.

Companion CD-ROM
This companion CD-ROM contains over 50 interactive e-Lab activities. Use these to practice and demonstrate your understanding of various topics throughout the Companion Guide.

This book is part of the Cisco Networking Academy Program series from Cisco Press. The products in this series support and complement the Cisco Networking Academy Program.
