Quickest way to restart debian is to use reboot command. Type reboot in the terminal and your debian server will restart immediately.
Restart Debian using shutdown command
Command Option -r in shutdown command use to reboot the machine. Unlike other two commands, shutdown command requires time argument to tell when to restart the system. You can use now as the time argument to reboot the system immediately or you can provide the time using +minutes format or hh:mm format.
shutdown -r now
This will reboot the debian system immediately.
shutdown -r +5
The above command will Restart the system in five minutes. You can cancel the scheduled restart using -c option.
I would recommend you to use systemctl command to restart the debian linux or use shutdown -r if you want to schedule the restart with time delay. Reboot command is a legacy command may not be available in future Debian releases.
