[RULE] Need help with scripting Vacuum

[Eugene Wong]

Hi all.

A few days ago, I reached the point, where I should start adding code to 
deal with options. I'm wondering how to go about doing it. I noticed that 
the Advance Bash Scripting Guide tells everybody how to go about dealing 
with portions of the arguement in chapter 9, but it doesn't really give any 
good theory.

For single letter options, I seem to notice that they usually begin with 1 
dash, & most often seem to allow "-abc" or "-a -b -c". Do we want to allow 
users to use the latter form? If I understand correctly, it would take a lot 
more code to deal with both. Since we want to allow both "-e" & "--empty", 
then there would be more parsing anyways.

What's the best way of dealing with options? Using "shift"?


Sincerely, and with thanks,
Eugene T.S. Wong
