How to set commands output as a variable in a batch file

Question

Is it possible to set a statement's output of a batch file to a variable, for example:

findstr testing > %VARIABLE%  echo %VARIABLE% 

Answer 1

FOR /F "tokens=* USEBACKQ" %%F IN (`command`) DO ( SET var=%%F ) ECHO %var% 

I always use the USEBACKQ so that if you have a string to insert or a long file name, you can use your double quotes without screwing up the command.

Now if your output will contain multiple lines, you can do this

SETLOCAL ENABLEDELAYEDEXPANSION SET count=1 FOR /F "tokens=* USEBACKQ" %%F IN (`command`) DO (   SET var!count!=%%F   SET /a count=!count!+1 ) ECHO %var1% ECHO %var2% ECHO %var3% ENDLOCAL
