Very useful info Ken - those are the couple of things I was actually
looking for. It'll certainly get me going.
One more thing, how do I do "if..else.." thing in there? Like:
if [ "$n1" == "$n2" ]; then
echo "something here"
elif [ "$n2" == "$(($n1*2))" ]; then
echo "something else here...."
.....
.....
fi
Cheers!!
