I need to restart from the root command line [duplicate]

I need help restarting/shutting down from the root command line, any commands I could use? I don't like hard resetting

Solution 1:

shutdown -r now

would do restart.

shutdown -h now

will halt/shutdown the system.

In Ubuntu's case, you can use reboot or halt, etc. They all invoke the shutdown command.

man reboot

may help.

For shutting down:

sudo poweroff

(It immediately stops all the processes and shuts down the computer.)

For restarting:

sudo reboot

Edit: Once you are already running as a root you needn't type sudo.
