Say if I have a command like:

 

"wmic path win32_battery get batterystatus"

 

Is there any easy way of setting the returned number into a variable, or do I need to stick to the old fashioned method of outputting to .txt with FOR loops?

There is no need to output to a (temporary) text file, but you need a FOR /F loop.

 

It also depends if the query returns a single value or several ones.

 

Examples (for single value returned):

FOR /F "tokens=* delims=" %%A IN ('wmic path win32_battery get batterystatus /format:list') DO SET my_%%A

or

FOR /F "tokens=1,2 delims==" %%A IN ('wmic path win32_battery get batterystatus /format:list') DO SET my_%%A=%%B

Ooh neat, I did not know about the /format:list parameter, that has simplified things a lot! Thankyou!

You are welcome.

Just in case a slightly more complex example for "pairs" of values:

@ECHO OFF
SETLOCAL ENABLEEXTENSIONS

FOR /F "tokens=1,2 delims==" %%A IN ('wmic path win32_logicaldisk get name^,volumeserialnumber /format:list ^|FIND "="') DO (
CALL :do_parse %%A %%B
)
SET Volume

GOTO :EOF

:do_parse
IF %1==Name SET Varname=Volume_%2
IF %1==VolumeSerialNumber SET %Varname%=%2
IF NOT DEFINED %VarName% SET %Varname%=No_Serial
GOTO :EOF
