sh != bash
You can either install bash from ports, or you can write your scripts in sh
without using bash extensions. For example, with sh you can do things like:
array="zero one to three four"
for x in $array; do
echo $x
done
However, you can't easily get the count of items. You could maybe do
something like:
set $array
echo "$# items"
but that's somewhat hackish.
