Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We'll make use of this in a failed_when statement."

A block of code is set as follows:

- name: query sessions
  command: /sbin/iscsiadm –m session
  register: sessions
  failed_when: sessions.rc not in (0, 21)

Any command-line input or output is written as follows:

$ source ./hacking/env-setup
