grep -q is a bad example, since it's a POSIX option that Solaris grep
doesn't implement, but should. (There's an open bug for it as part
of the series of "Solaris /usr/bin utilities should implement all
POSIX options that they can without breaking compatibility" bugs.)
It's used for scripts to get an exit status from grep without grep
printing output (i.e. a more efficient version of "grep > /dev/null 2>&1").
