Reboot mac using command line

Sometimes it is necessary to restart a Mac remotely, especiallyapple-logo when there's no direct access to the GUI. A quick way to do that is by logging on to the server with an admin account using SSH (assuming ssh is permitted) and running the following command:

sudo /sbin/shutdown -r now

shutdown: will shutdown the system

-r: stands for "restart"

now: do not wait for timeout and restart the system right away
