I need to restart from the root command line

Question

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.

Solution 2

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.

"poweroff" works too to shutdown w/o reboot ;)

The OP mentioned that he is already inside a root shell, so no sudo is required. Otherwise your answer is ok, except that you could add a bit additional explanations what those commands do... (because it appeared in the Low-Quality review queue because of its length)
