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: "Log in as pi and enter the password you chose earlier with raspi-config."

A block of code is set as follows:

self_destruct() {
  pkill -KILL -u pi
  umount /home/pi
  rm -rf /home/pi
  mkhomedir_helper pi
  rm -rf /home/.ecryptfs
  rm -f $COUNTFILE
  # rm -f /home/slatfatf.sh
}

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

pi@raspberrypi ~ $ ip addr show wlan0

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: "Under the Channel group, click on Remote."
