Holy Crap!!!

I had to try it....:)  This should solve your problem:

#!/bin/sh
# Antitest
while :
do
        if [ -d test ]; then
           cd test
        else
           cd ..
           if [ -d test ]; then
              rm -rf test;
           else
              exit 0
           fi
        fi
done

Very Cool..:)
