Well, yes you can, it will just ask for user input. Also, I think the majority of situations described
in the [wiki](https://trac.macports.org/wiki/SummerOfCode2014_interactive) are not
actions usually done in scripts IMO.

If that’s implemented, I think it’s fine.

Yeah, but that way the user will have to learn and use a new command name and update his/her aliases to use the interactive command.
