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: "The easiest way to access the PPA to install Salt is using the add-apt-repository command."

A block of code is set as follows:

def sleep(length):
    '''
    Instruct the minion to initiate a process that will sleep for a given period of time.
    CLI Example:
    .. code-block:: bash
        salt '*' test.sleep 20
    '''
    time.sleep(int(length))
    return True

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

# sudo salt-key -f myminion
Unaccepted Keys:
myminion: a8:1f:b0:c2:ab:9d:27:13:60:c9:81:b1:11:a3:68:e1

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "If the system asks whether you should accept a gpg key, press Enter to accept."
