假如你需要3位随机密码：
@echo off
color 0d
set d=1
if exist %d%.txt goto 1
if not exist %d%.txt goto s1
start %d%.txt
:1
echo.测试密码
set /p e=请输入密码
for /f "delims=" %%a in (%d%.txt) do (
      if "%e%"=="%%a" goto 2
      if "%e%"=="" goto 1
)
echo.密码错误&
ping /n 3 127.1>nul
cls
ping /n 1 127.1>nul
goto 1
:s1
set/a "a=%random%%%6+1"
set/a "b=%random%%%5+1"
set/a "c=%random%%%9+1"
echo.%a%%b%%c%>>%d%.txt
echo.修复成功！！！
pause>nul
start %d%.txt
cls&goto 1
:2
color 0d
echo 您成功了！！！
ping /n 2 127.1>nul
cls
ping /n 5 127.1>nul

exit
