Yes.

Learn about FOR /F with tokens and delims:

You don't really need a temporary file.

Namely:

@ECHO OFFSETLOCAL ENABLEEXTENSIONSFOR /F "tokens=1,2 delims= " %%A IN ('bcdedit /enum all /v') DO (IF %%A.==identifier. SET %%A=%%BIF %%A.==description. SET %%A=%%BIF /I %%B.==grub4dos. GOTO :out):outSET identifierSET descriptionPAUSE

If you really want to create the text file, replace the FOR line with:

bcdedit /enum all /v>C:\List.txtFOR /F "tokens=1,2 delims= " %%A IN (C:\List.txt) DO (

Hi, Jaclaz

I have a question. If menu boot contain Whitespace character, How can I edit your command to get some text which I want. i.e Menu boot is "Grub For Dos". I tried 

IF /I %%B.=="grub for dos". GOTO :out

but It's not working.

Thanks

Sure it is not.

"%%B" in that case would be only "grub" as you have delims set to [sPACE] and tokens set to 1 and 2.

Try with tokens=1,* <- the idea of giving you a reference is that you study the syntax, so that you can make changes yourself, but not "random" ones.

Also you need quotes on both sides, like

IF /I "%%B"=="grub for dos" GOTO :out

Thank you for your quick reply, Jaclaz

Now I understand what differences between tokens=number and tokens=*.

Have a nice day
