Batch Command Line Arguments

Question

Is it possible to pipe in a .txt file as a command line argument to a batch file?

For example, I am looking to call

./program components.txt

Then use every line of components.txt as arguments to a function I call inside my batch file.

If args.txt contains a list of command-line arguments to your executable (one per line), you could use something like this:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set ARGS=
    for /f "delims=" %%a in ('type args.txt') do (
      set ARGS=!ARGS! %%a
    )
    .\program %ARGS%
    endlocal

Does it matter if ./program is not an executable? What if it is a local command?

It doesn't matter whether program is an internal cmd.exe command or an executable. However if it is a shell script (batch file), use call to run it (e.g., call .\scriptname %ARGS%).

Sorry let me specify... I'm calling "p4 sync %ARGS%" on that line... NO executable is being used from an internal scope.

The for command reads the file args.txt and constructs the ARGS environment variable as a single space-delimited string containing the lines from the file (i.e., spaces between instead of newlines). What you do with that string is up to you.
