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.
Please be aware that most Windows PCs do nothave grep available
either.
But if you can do it with grep, you can do it within RB using a regEX
I'm not a grep or RegEx expert, however I bet using these tools I
can't have a full feature command line parsing.
Looking at how works getopt() there are plenty of options and rules
to follow.
BTW, using RegEx is a better idea than using grep, thanks!
