How to set command’s output as a variable in a fichier batch

2 
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, vous pouvez utiliser your double quotes without screwing up the command.

Now if your output will contain multiple lines, vous pouvez 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
