为什么我的关机脚本不起作用？

Question

如果我在没有脚本的情况下运行shutdown命令，它就在Windows 8.1上运行它。但是，当我从这个脚本运行它有在cmd中所示的一些错误的语法....感谢您的帮助

@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
