Even when the user used an illegal option to get the help? While nearly all programs in the tree have a usage message, it is given only in response to a mal-formed command line. : > I personally think encouraging -? is dangerous given its potential : > danger, as others have pointed out : : Good. I can accept that and switch to using another flag for getting : help - BUT i think also that FreeBSD should use this flag consistently : for all or most of the programs and it should be documented in a well : known and easy to find place. : : What should the help flag character be ? I don't know. One thing that you can do is start your option string with :, so no errors happen. Another is to set opterr to 0. Since I don't have a good answer, I'm thinking of just backing out all the ? changes I've made (except for pkg, which others are working on).
