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: "Use a real domain name that you or your company controls. Do not use a bogus domain name such as .local or .localdomain."

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

root@kalibook :~#  apt-get -y install gedit

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: "Pull up a terminal window by clicking in the menu bar in the upper left hand corner and go to Applications | Accessories | Terminal. This will bring up the terminal or command-line window."
