        @echo.
        @echo 时间: %time%
        @echo.
        @echo 倒计时: %Countdown% 秒

)

密码输入

@echo off
set count = 0
REM REM 设置计数

:Input_password
        set /p string=Password:
        set /a count = %count% + 1

if "%string%" == "password_123" goto Pass_password
REM REM 如果密码匹配则进入 Pass_password 代码块

if %count% == 3 goto Quit
REM REM 如果尝试次数达到三次则进入 Quit 代码块

goto Input_password

:Pass_password
        echo You got the correct password! ^^_^^
        REM REM 验证正确密码的功能区

比较两个文本的差异

@echo off
set n=0
setlocal enabledelayedexpansion

(for /f "delims=" %%i in (test1.txt) do (
        set /p str=
        set /a n+=1
        if not "!str!"=="%%i" (
				echo. 第 !n! 行不同！
				echo. txt1 第 !n! 行: %%i
				echo. txt2 第 !n! 行: !str!
				echo.
        )
))<"test2.txt"
