Turning off the Raspberry Pi
Now that we have some of the Raspberry Pi’s up and running, we are playing with some of the installed games and poking around the system.
One thing that confused us was how to turn off the RPI. Just yanking the power cord from a computer is a very bad idea; you should always properly shutdown the system to make sure the filesystem is in a consistent state.
Since it was not clear how to turn off the machine using the GUI, I just opened the terminal and used the command:
sudo poweroff
That appeared to work as the RPI shutdown and stayed off.
