The double parentheses cause a >syntax error. Bash in its current incarnation has neither integer variables (the `typeset -i' stuff) nor arithmetic expression evaluation (the `((...))' stuff). It doesn't have array variables, either. I don't really know what Brian's plans for this are, but I did write an expression evaluator and send it to him. I have put in integer variables, though not in a way that's really satisfactory, and I haven't sent that code to Brian. You could probably hack this stuff to use regular variables and expr without too much trouble, or use pushd and popd.
