Does %* in batch file mean all command line arguments?

Question

Does %* in batch file mean all command line arguments?

Answer 1

Yes. According to the official Microsoft documentation:

The %* batch parameter is a wildcard reference to all the arguments, not including %0, that are passed to the batch file.

Answer 2

Besides this, a comment by @kobkira notes that you can take only up to 9 arguments in conventional syntax. Like this if you want to get n number of arguments in separate array style variables, use this syntax:

@echo off & setlocal enabledelayedexpansion & set "n=30"
for /l %%a in (1,1,%n%) do (
  for /f "tokens=%%a delims= " %%b in ('echo %*') do (
    set "arg[%%~a]=%%~b"
  )
)
