模仿terse前辈的代码
@echo off&setlocal enabledelayedexpansion
type a.txt>b.txt
set n=-1
:1
for /f "delims=" %%a in (a.txt) do set/a n+=1&call :lp "%%a"
ping 127.1 /n 3 >nul &set n=-1&goto 1
:lp
if not !n! equ 0 (
for /f "skip=%n% delims=" %%a in (b.txt) do (
set /a m=!n!+1
if not "%%a" equ "%~1" echo &echo 第!m!行改变
goto :eof
)
)
for /f "delims=" %%a in (b.txt) do (
if not "%%a" equ "%~1" echo &echo 第1行改变
goto :eof
)

作者: bat-zw 时间: 2008-5-12 20:53 标题: 是不是可以简单点：
前提是先将a.txt备份如b.txt(实际中请加上完整路径)
@echo off
fc a.txt b.txt>nul 2>nul
if errorlevel 1 echo a.txt已被改动!
pause>nul

提示一下思路
先拷贝一个。。。
后对比....
有改动。。。就报警提示。。。
