Math in general is tricky (to say the least) in bash. You certainly don't
want to do any kind of heavy-duty maths in bash, but for simple stuff the
"bc" program is a good solution (that's how I do all my bash-maths).
Something like this:
# increment j:
j=`echo "$j + 1" | bc`
# add 3 and 2
k=`echo "3+2" | bc`
echo $k
