Saving command into variable

I've question about this variables.How can I store result of a command into a variable? For example: saving drive serial into location variable. thanks. E.g:

@ECHO OFF
SET location=vol
ECHO We're working with %location%
Solution 
  • for /f "delims=" %%x in ('your command and parameters') do set "var=%%x"

    where the 'single quotes' are required around the command from which you wish to save output.

    Edit - now we know which command.

    Comment - one variable can contain up to ~8,000 characters.

    Here's a routine that will set the values in $1...$whatever and the entire set in $all with each field enclosed in angle-brackets.

    @ECHO OFF
SETLOCAL
SET "$all="
FOR /f "tokens=1*delims=:" %%a IN (
  'systeminfo 2^>nul^|findstr /n /r "$"'
  ) DO (
 SET "$%%a=%%b"
 FOR /f "tokens=*" %%c IN ("%%b") DO CALL SET "$all=%%$all%%<%%c>"
 SET /a max=%%a
)

SET $
pause
FOR /l %%z IN (1,1,%max%) DO CALL ECHO %%$%%z%%

GOTO :EOF
