how to shutdown a linux machine, including the root password, in 1 line?

Question

How do you include the root password, say for shutting down an ubuntu machine?

like,

sudo shutdown now

is it possible to include the password on this 1 line? like an extra parameter?

reason for this is I am trying to play with this app named azr remote prompt which lets you send commands from your blackberry to your ubuntu machine and it seems like a 1 way trip. you send commands, but you don't get any response from the computer.

Yes, sudo has a '-S' a switch that allows it to read in the sudo password from stdin. All you have to do is echo your root password - so for your instance it would look like this (replace [PASSWORD] with your root password)

history -d $((HISTCMD-1)) && echo '[PASSWORD]' | sudo -S shutdown now
