I try your command on a Microsoft XP pro and I win

nicolas AT cl12369n ~ s=1
  $ find -type f -name '*' | (   read f;   cc=-1;   echo "";   while
[ ! -z "$f" ]; do     cc=$(( 1 + $cc + $( echo "$f" | wc -c) ));
  echo -e "\e[F$cc\e[K";read f;   done;   echo -e "\e[F$cc chars"; )
1789980 chars

Where is the problem?

bye
