我找一个批处理文件内容如下
Set flag=
dmi.exe /f

:check
If Not Exist DMIINFO.TXT Goto check
chcp 936>nul
For /f "tokens=2 delims==" %%i In ('findstr /bi "Product_Name" DMIINFO.TXT') do set type=%%i
Echo 你的型号是：%type% 系统正在分配驱动
ping -n 6 %computername%>nul
Set type=%type:*-=%
For /l %%i In (1,1,9) Do If "%type:~1,1%"=="%%i" Set type=%type:~0,2%
For /f "delims=" %%i In ('dir /a-d /b "*%type:~0,3%*.txt" 2^>nul') do (
Set flag=1
For /f "delims=" %%j In ('dir /ad /b^|findstr /ivx /g:"%%i" 2^>nul') do rd /q /s "%%j" 2>nul
)
Del /f /q *.txt 2>nul
If Not defined flag (
For /d %%i In (*) Do rd /q /s "%%i" 2>nul
Echo 无法找到符合%type%笔记本的驱动
Echo 此窗口20秒后自动退出
ping -n 20 %computername%>nul
)
Del "%~0"
pause

我不是很清楚 For /f "tokens=2 delims==" %%i In ('findstr /bi "Product_Name" DMIINFO.TXT') do set type=%%i
这一行里的意思。
如果我想修改。从INFO.txt里取得一个信息怎么修改
INFO.txt的内容是如下我用红色表表示我要取得的内容
哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪哪?

多看看老帖子，对照着for /?学习。

看的头都晕了
我把这行改了怎么就不工作呢？
For /f "tokens=2 delims==" %%i In ('findstr /bi "Product Name" DMIINFO.TXT') do set type=%%i


Product Name这个原先有_ 下滑线 我改成没有就不正常工作了？还有我要提取的东西和先前写这个DAT的人的东西不太一样
他先前的是DMIINFO.TXT是如下


Manufacturer_Name(Type1,Offset04h) = Compal
Product_Name(Type1,Offset05h) = CL51
Version(Type1,Offset06h) =
Serial_Number(Type1,Offset07h) =

已经搞定了非常感谢~
