您需要的是-P，而不是-p。它区分大小写。另外请注意，您必须是 root 才能这样关机。

目前，有多种进入方式。摘自man shutdown：

       TIME  may  have  different  formats, the most common is simply the word
   'now' which will bring the system down immediately.  Other  valid  for‐
   mats  are  +m,  where m is the number of minutes to wait until shutting
   down and hh:mm which specifies the time on the 24hr clock.

例子：

$ sudo shutdown -P 20:30
[sudo] password for ward: 

Broadcast message from ward@sekhmet
(/dev/pts/0) at 20:14 ...

The system is going down for power off in 16 minutes!
