爲什麼我的關機腳本不起作用？

Question

如果我在沒有腳本的情況下運行shutdown命令，它就在Windows 8.1上運行它。但是，當我從這個腳本運行它有在cmd中所示的一些錯誤的語法....感謝您的幫助

@echo off 
TITLE shutdown timer 

SET /P minutes=Enter minutes till shutdown or "no" to stop running shutdowns: 

IF "%minutes%" == "no" (
    shutdown /a 
    echo shutdown aborted 
) ELSE (
    SET /A seconds = %minutes% * 60 
    shutdown /s /f /t %seconds% 
) 
pause
