What you are saying here is at least misleading. I just started up sh on 9.1 RELEASE and tried: $ A=-z $ if [ "$A" "" ] ; then echo z ; fi z $ if [ "$A" "1" ] ; then echo z ; fi $ if /bin/[ "$A" "" ] ; then echo z ; fi z $ if /bin/[ "$A" "1" ] ; then echo z ; fi $ Although "-z" is quoted, it is seen as an operator. It does not seem to have anything to do with whether the build-in or external "[" is used.
