You can find documentation and help for the Raspbian Linux distribution at http://www.raspbian.org. In
addition, because Raspbian is based on the Debian Linux distribution, there is a lot of other
documentation available. Most of the Debian documentation applies to Raspbian as well. The
following are a few excellent references for Debian:
The Debian Administrator’s Handbook, which is available from debian-handbook.info
The Debian User Guide, which you can easily access via the Raspbian GUI
The Debian Project’s website, http://www.debian.org/doc/, which offers documentation as well as
helpful user forumsInteracting with the Raspbian Command Line
When you first booted your Raspberry Pi, you did not have to provide a username and password.
However, after the initial boot, on all subsequent boots, you see a Raspbian login screen. Listing 2.1
shows how you log in to your Raspberry Pi. By default, you enter the username pi and the password
raspberry. Notice when the password is typed in, nothing appears on the screen. This is normal.

Listing 2.1. The Raspbian prompt looks like this:
pi@raspberrypi ~ $This is also called the Linux command line. At the command line, you can enter commands to perform
various tasks. In order for a command to work, you must type in the command in the proper case and
then press the Enter key.
Did You Know: What Is the Linux Shell?
When you enter commands at the command-line prompt, you are using a special utility
called a Linux shell. The Linux shell is an interactive utility that allows you to run
programs, manage files, control processes, and so on. There are several variations of
the Linux shell utility. Raspbian uses the dash shell by default.
