Maybe better style:
# Put grep's return code someplace safer than $?
rc=${?}
case $rc in
0)
# we found what we wanted
# do X
;;
*)
# we didn't find it
# do Y
;;

Not really evident as good style if there are only two cases (0 and
everything else). Shows to great advantage if there are more than two
cases to consider.
