shutdown volumio

Hi
I have a raspberry pi with a piface and display . How can i shutdown de raspberry in the correct way ?
Is there any way to disable and enable raspyfi without unplugging the power cable?

sudo shutdown -h now
Then hit the return key on keyboard.

There is the ‘poweroff’ command in the ‘System’ menu of the Volumio Web-GUI. Presumably that does the same thing as ‘sudo shutdown -h now’. There is also a ‘Turn Off’ command on the main menu. Not sure exactly what that does …
