用批处理实现的倒计时代码，利用了 debug等命令，全力打造，值得一看。
复制代码 代码如下:
@echo off
echo exit|%ComSpec% /k prompt e 100 B4 00 B0 12 CD 10 B0 03 CD 10 CD 20 $_g$_q$_|debug>nul
chcp 437>nul
graftabl 936>nul
set all=20
:start
if "%all%"=="0" goto end
cls
set /a all=%all%-1
echo.
echo.
echo.
echo.
echo %all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%
echo %all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%
echo %all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%
echo %all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%
echo %all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%
echo %all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%%all%
echo wscript.sleep 500>>ri.vbs &call ri.vbs &del ri.vbs
goto start
:end
cls
echo The End
pause
