Linux Shutdown and restart __linux

This paper takes CentOS system as an example to explain. Reboot command: reboot: Reboot shutdown-r now: Reboot immediately (root user) Shutdown-r 10:10-minute automatic reboot (root user) Shutdown-r 20:35: In time 20 : 35 time Reboot (root user use)

If you set the reboot through the shutdown command, you can cancel the restart shutdown command by using the shutdown-c command: Halt: Shut down immediately poweroff: Shut down immediately shutdown-h now: Turn off the machine immediately (root user uses) Shutdown-h 10:10 minutes after automatic shutdown

If you are setting the shutdown via the shutdown command, you can cancel the reboot with the SHUTDOWN-C command
