Is there something wrong with my eyes? I've read the code on floor 24 many times, but I can't see a single "defined". Lao Tu, can you take a look again?

Sorry, I should have looked at the code on floor 24 plus the code on floor 7. I made a mistake.

Also, there might be an issue with missing or extra parentheses in your code. I can't tell.

Oh, there's neither more nor less. I can't see it either.
Don't think about it anymore, going to sleep.

The number of loops for the code on floor 39 to 1.txt is equal to the number of lines in 2.txt multiplied by the number of lines in 1.txt, so the efficiency is much lower.

Has the landlord's problem been solved?

You claimed that you didn't even graduate from junior high school, but now I simply can't believe it. How can someone who didn't graduate from junior high school write programs so skillfully? You've confused me, someone who claims to have at least a college education, completely.

If I were ten years younger, I don't think I would come here for help. It's embarrassing. At most, I would stay up all night to thoroughly understand all the commands and then figure out a way, but I'm getting old, and indeed, I can't do it anymore.

Going to sleep now. I've learned a lot today. One learns until one dies. Thanks everyone!

Still, Xiao Lou's looks better. Compare with yours.


@echo off&setlocal enabledelayedexpansion
for /f "tokens=1*" %%i in (1.txt) do set "%%j=%%i"
   for /f "delims=" %%a in (2.txt) do (
      if /i "%%~xa"==".cat" (
        for /f "tokens=1*" %%i in ('crc32 %%~fsa') do if defined %%j >>crc.txt echo !%%j! %%j %%i)else (
        expand %%~fsa %temp%\%%~na.cat
        for /f "tokens=1*" %%i in ('crc32 %temp%\%%~na.cat') do if defined %%j >>crc.txt echo !%%j! %%j %%~fsa
))
pause

I took another look at the description in the top post, the original poster's sentence.
Now I get a variable value, such as HEDY, which is the first value in the line in file 1.txt.
I perform a CRC32 check on the files in the path in 2.txt (if it's a compressed file, first EXPAND it), run CRC32.EXE, assume that the CRC output result is the second Token in the first line, and then compare it with the value in the second line of file 1.txt. IF FIND, then assign the corresponding path to a variable.
It seems to be to find the required file name according to the value of a variable, not to compare all.
The following: the value of str is the one to be found. It can be multiple, separated by spaces.
:


@echo off&setlocal enabledelayedexpansion
set str=HEDY LEGEND
for /f "tokens=1* delims= " %%a in (1.txt) do set "%%a=%%b"
for /f "delims==" %%i in (2.txt) do (
  if /i %%~xi==.cat (
     for /f "delims=" %%j in ('crc32 %%~fsi') do set "var=%%j"
   ) else (
    expand %%~fsi %temp%\oembios.cat
    for /f "tokens=2" %%j in ('crc32 %temp%\oembios.cat') do set "var=%%j"
    del/q %temp%\oembios.cat >nul 2>nul
  )
    for %%a in (%str%) do if /i "!var!"=="!%%a!" echo %%a !var! %%i
)
pause

My motherboard has OEM characteristics, and I have a large number of OEM BIOS files available to replace the files required by the system. To find the accurate OEM BIOS files, I put them in specific folders one by one so that the program can automatically find them.

It's a bit messy. I'll give you a solution for the above problem (requires crc32sum.exe)



@echo off
for /f "delims=" %%a in ('dir /s/a-d/b D:\*.CA*') do call :xxx "%%a"
pause

:xxx
set "FliePath=%~dp1"
set "Flie=%~nx1"
if "%Flie:~-1%"=="_" (
    EXPAND "%~1" "%temp%\OEMBIOS.CAT" >nul
    for /f "tokens=1 delims=* " %%i in ('crc32sum.exe -b "%temp%\OEMBIOS.CAT"') do set "crc32=%%i"
    ) else (
    for /f "tokens=1 delims=* " %%i in ('crc32sum.exe -b "%~1"') do set "crc32=%%i"
)
for /f "tokens=1 delims= " %%k in ('type 1.txt^|find /i "%crc32%"') do echo 文件"%~1"	对应品牌%%k

Function description: Enumerate CA* extensions on drive D. If the extension is CA_, use EXPAND to extract to the temporary folder and then use crc32sum.exe to verify. Otherwise, directly use crc32sum.exe to verify. Assign the verification value to the variable crc32. Finally, filter and display the OEM results. crc32sum.exe can be downloaded from my cloud disk.

This is my execution result

File "D:\oembios\XP_ACER_OEM\OEMBIOS.CA_" corresponds to brand Acer
File "D:\oembios\XP_ASUS_OEM\OEMBIOS.CA_" corresponds to brand Asus
File "D:\oembios\XP_COMPAQ_OEM\OEMBIOS.CA_" corresponds to brand Compaq
File "D:\oembios\XP_DELL_OEM\OEMBIOS.CA_" corresponds to brand Dell
File "D:\oembios\XP_HP_OEM\OEMBIOS.CA_" corresponds to brand Hewlett-Packard
File "D:\oembios\XP_IBM_OEM\OEMBIOS.CA_" corresponds to brand IBM
File "D:\oembios\XP_IBM_OEM\OEMBIOS.CA_" corresponds to brand IBM
File "D:\oembios\XP_Lenovo_OEM\OEMBIOS.CA_" corresponds to brand LEGEND
File "D:\oembios\XP_Lenovo_OEM\OEMBIOS.CA_" corresponds to brand LEGEND
File "D:\oembios\XP_SONY_OEM\OEMBIOS.CA_" corresponds to brand Sony
Press any key to continue. . .
