I *found* the text where the description of let is documented. But what do I have to type if I want to increase a shell variable? The syntax of "arithmetic expression" remains unclear and an example, how to do
a = $b + $c * $d and a = ($b + $c) * $d (because this demonstrates also braces in expresions which might be misinterpreted by the shell) would be really helpful. Kind regards Andreas.
