Configuring Raspberry Pi OS

Now we are connected, let's do a few things to prepare the Raspberry Pi for use, such as changing the user password and changing the hostname to make the Pi more secure.

We can perform many of these tasks with the raspi-config tool, a menu system to perform configuration tasks on Raspberry Pi OS. We start it with another tool, sudo, which runs raspi-config as root, a master user. Refer to the following command:

sudo raspi-config

The raspi-config interface will appear, as shown in Figure 4.5:

Now we've accessed raspi-config, we can use it to change some of the settings on the Raspberry Pi.
