This usually gives a success/failure result but does not give any hint
of the actual returned value.  Dan wanted to test for an empty response.

Another way to tell if the return is empty would be a simple test.
 [ "X`command`" == "X" ]  would return a true if the result of `command`
were empty (no value or the empty string).
