   Hmmmmm..... Off the top of my head, how about this?:

COMMAND=`basename $0`
DIR=`type $COMMAND | sed -e 's:^.* /:/:' -e "s:/$COMMAND$::"`
echo "Parent directory of \"$COMMAND\" is \"$DIR\""

  It works under sh.  Although I am sure there is an "awk" script that might
do it in less lines, I bet this is possibly faster.
