I have a console application requiring a complex mix of command

Is there someone that already solved the problem? and how?
The obvious answer is: GREP. All programmers should know how to
use grep, at least in a basic fashion. And if your command line
options are too complex for basic grep, you should almost
certainly rethink them.
using grep it's an interesting idea, however I would avoid to open
a shell from my application to invoke grep.
A better solution of grep would be calling getopt() via a declare
which is standard in libc. But again this is something external and
only available to Mac OS X and Linux.
I'd prefer to have something written in RB and possibly cross-
platform.
I meant regex. Your diy solution will almost certainly be doable
using a suitable regular expression.
