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, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "The search method has a similar format to the knife command."

A block of code is set as follows:

all_users = search(:users, 'id:*')
users_s = search(:users, 'id:s*')
all_nodes = search(:node, '*')

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

$ knife data bag show credentials aws

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: "Once there, a tab labeled Chef Server will be present at the top of the page".
