I cut and pasted your code and it works fine for me (reading with -n 1). Is it possible that the version of bash that is being invoked isn't the same one executed as your login shell?

You could try something like this that doesn't depend on reading character by character:


Code:
while read buf
do
    vbuf="${buf//[^aeiouAEIOU]/}"
    v=$(( v + ${#vbuf} ))
done <$file
echo "$v vowels"



This works in both bash and Kshell.
