Does it handle quoted args?
arg1 "arg2 with spaces" arg3 ...

Yes but I don't think it handles more than one arg.
From what I can tell the windows one didn't.

This works in windows:
Program: cmd.exe
Args: //k echo "[Filename]" && echo [Artist]
The win32 API CreateProcess() takes a single string with the full command line to execute and splits the args itself - the caller just sends the whole thing. The ShellExecute() takes the executable name plus a second string with all args as well.

Yeah, I doubt that will work on Mac as I wrote it. If it doesn't I'll see about splittng the args.
MrBiff:
Great, thank you very much.
The argument passing and quoting rules for commands executed via cmd.exe were insanely stupid and naive. One of the rules: a single string argument that has exactly two double quotes, at the beginning and end, gets handled specially. So it was common to think of these command arguments as a single string.
PowerShell, while a very odd duck, supports handling arbitrary command line arguments via single base64 encoded string. This eliminates all the impossible-to-handle quoting issues that have been present in the MS command line environment for ~40 years.
The first time I had to write Win32 code, and was gobsmacked when I read that CreateProcess took a string argument (...use quoted strings to indicate where the file name ends and the arguments begin...). Oye.

I'll definitively need arguments as individual ARGV items.
