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: "Once the machine has booted, you will need to log in with root and a password of toor (root in reverse)."
Any command-line input or output is written as follows:
root@bt:~# /etc/init.d/networking start
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: "On the Downloads page, you will see a drop-down window that you will use to select the version of the distribution that you want to download."
