Did you go through the manpages? The 'shutdown' manpage provides procedure followed by it and when it uses the 'reboot' command.

Hi,

The difference between a "shutdown" and a "reboot" command issued on a system is as follows :

shutdown - this will gracefully terminate all the running processes in a sequential and consistent fashion and then reboot the system. This command should be used in multi-user mode.

reboot - this will forcibly terminate all running processes thus making the system shutdown rapidly and then reboot the server. This command should only really be used in either single user mode or maintenance mode.

Please see their respective man pages - man 1m shutdown and man 1m reboot.

Regards,

Mark

the main difference between them:

reboot : kills the all process to restart.

shutdown -ry X : terminates the all process gracefully manner.

So , use shutdown -ry X, it is better if you do not really need reboot.
