16楼的老兄,还是不行哦
我的原文件是
@ECHO OFF
GOTO %CONFIG%
:RECOVER
PATH C:\DOSTOOLS;C:\DOSTOOLS\COMMAND
SET TEMP=C:\DOSTOOLS\TEMP
LH DOSTOOLS\COMMAND\DOSKEY
LH DOSTOOLS\COMMAND\MOUSE

GOTO END

:BACKUP

请问怎么替换:\GHOSTSYS前面的盘符啊?谢谢

注意你的套嵌顺序！

@echo off&setlocal enabledelayedexpansion
for /f "tokens=*" %%i in (test.txt) do (
set "n=%%i"
for %%a in (c d e g h i j k l m n o p q) do (
set n=!n:%%a:\GHOSTSYS=F:\GHOSTSYS!
)
echo !n!>>test2.txt
)

谢谢各位大哥的解答,18楼是正解!已经OK了
