Hello everyone! Please help take a look at how this should be written. A.TXT contents QQ Speed QQ Island QQ Fengshenji QQ Huaxia Baby Tank Snowstorm Love Sky ........... B.TXT contents QQ Island QQ Speed Speed Baby Tank Baby The contents of A.TXT are the standard. For each line in B.TXT, if it is different from A.TXT, find it and put it into C.TXT (for example, Speed and Baby) [ Last edited by lbccyxs on 2010-7-29 at 10:51 ]

@echo off :: Extract the differences between the two files into some file :: cd.>3.txt for /f "tokens=1* delims=:" %%i in ('findstr /n . 1.txt') do ( for /f "tokens=1* delims=:" %%x in ('findstr /n . 2.txt') do ( if %%i equ %%x if not "%%j"=="%%y" (>>3.txt echo 1:%%j&>>3.txt echo 2:%%y&>>3.txt echo.) ) ) ------------------------ http://www.jb51.net/list/list_106_2.htm

This one is relatively slow (mainly because there are a lot of games), but it can meet the requirement. The purpose is to delete expired games. cd.>c.bat for /f "tokens=" %%i in (a.txt) do ( find "%%i" b.txt \|\| >>c.bat echo RD /S/Q K:\网络游戏\%%i) del 1.txt&del a.txt&del b.txt notepad c.bat [ Last edited by lbccyxs on 2010-8-3 at 22:32* ]

Wouldn't a single line of findstr do it?
