Errata for The Linux Philosophy for SysAdmins

Chapter 1, Page 9 (approximate Kindle location 831)

The paragraph starting at the bottom of the page should read: “This book is not about learning new commands. Rather, it is about using the common and well-known commands with which you should already be familiar to illuminate the underlying structure of Linux at the command line. Think of this book and the commands you will use in the experiments like the X-rays, CT scans, and MRI’s that a doctor uses to reveal the inside of a human body. This book will show you how to use some simple Linux commands to reveal the underlying structure of GNU/Linux.”

Experiment 7-3

The code for Experiment 7-3 is incorrect. This code is correct; it removes the semicolon from between grep and Summary.

for I in rpm -qa | sort;do echo $I; rpm -qi $I | grep Summary ; done
