I think  having this  in an example  is fine. We're  using "grep  -q" in
other places, too. Not that it matters  much, but ‘-q’ is part of SUSv3.
Maybe vendors should be asked to implement it therefore. :)

In any case,  I think its use  in examples of documentation  is fine. If
you're plagued with an implementation that doesn't implement -q, you get
to work around it.
