Book description

For each exam objective, the key commands and configuration files will be detailed. The CompTIA Linux+ Portable Command Guide provides a single point of reference while studying for the certification exams as well as a valuable resource after the candidate has successfully passed the exams.

 

The guide summarizes all commands, keywords, command arguments, and associated prompts. Configuration examples are provided throughout the book to give a better understanding of how these commands are used. This guide is not meant to replace any existing learning materials but rather serve as a supplementary guide to assist readers in the proper use of the many different commands to use on a regular basis and that are required to successfully pass the exams.
