9. Supplementary notes

9.1 Turning off the Raspberry Pi

The Raspberry pi has no power switch. To turn it off, please type sudo halt into the

command prompt. After the screen turns black, you may unplug the power supply.

9.2 Resizing the file system

In case one uses an SD card bigger than 2GB it might be reasonable to resize the root

file system to use the whole space of the SD card. To do so, please follow these steps:

1. Start the Raspberry Pi and log in.

2. Type sudo raspi-config into the command prompt.

3. In the configuration dialog that opens, choose the entry “expand_rootfs” and

press [Enter].

4. After the operation has finished, choose <Finish> by pressing the [TAB] key

twice and press [Enter].

5. Answer the question about the reboot with <Yes>.
