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: "Extract 2015-09-24-raspbian-jessie.img to your Home folder."

A block of code is set as follows:

# passwd
root@raspberrypi:/home/pi# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@raspberrypi:/home/pi#

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

$ sudo apt-get install fake-hwclock

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: "Type the IP address of the Raspberry Pi into the Host Name box and click on Open."
