That's definitely wrong: 'gnuclient -q $*' is just a string, not "call
this program". Also, there's no need to use [ ] (a.k.a. /usr/bin/test)
for this purpose. Just check the program's exit status directly:
if gnuclient -q $*; then
# success
else
# failure
fi
Alternatively, you can look at $? for the command's exit status.
