Difference between shutdown /p and shutdown /s ?

Hello,

I followed Brink's tutorial here: Shut Down Computer in Windows 10
And I saw that there are 2 ways to fully shutdown Windows through cmd: /s and /p.
What is the difference between these 2, if both of them are said to perform a full shutdown?

Thanks

hello, the /p will stop and tell you have programs running ,and to close them before shutting down . /s will just shutdown with no warning messages if apps are running or if you a text file or such open that you might be working on ..that's the way I read it anyway

Open Admin command and type: shutdown /?

/p Turn off the local computer with no time-out or warning.

option 8 says different .not sure why .
