Conventions

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

Code words in text are shown as follows: " You'll need a Puppetmaster and a set of existing manifests in /etc/puppet."

A block of code is set as follows:

#!/bin/sh

syntax_errors=0
error_msg=$(mktemp /tmp/error_msg.XXXXXX)

if git rev-parse --quiet --verify HEAD > /dev/null
then
    against=HEAD

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

# puppet parser validate/etc/puppet/manifests/site.pp 
err: Could not parse for environment production: Syntax error at end of file at /etc/puppet/manifests/site.pp:3

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "clicking the Next button moves you to the next screen".
