Please remind me how to run commands.

You do not need to run commands: all that can be done from the moOde's library configuration page.

If you are referring to the shutdown -h now command you can enable web ssh in the moOde configuration too, then you just enter the command prepending sudo to it as-is, and hit enter.

sudo shutdown -h now

is the complete command.
