POSIX states that sh(1) should be able to evaluate expressions,
so you can do something like
while [ $FILES != 0 ]
do
echo -n '* '
FILES=$[$FILES - 1]
done
But I haven't seen a sh anywhere that is already capable of doing this
(not even the one I am writing myself for Minix... yet.).
Maybe somebody knows if a new ksh can do this?
