If you know programming languages like C or java, you are able to cope with (bourne type) shells. The logics is not too different from the formers', the syntax might be. It's just a matter of exercise. If copy / pasted code doesn't work for you, you indeed should compare the versions. All shells, be it bash or ksh or what have you, evolve over time, and functionality found in recent ones may not be available in older versions. Same is true between shells - although bash and ksh both are descendants of the original sh, and are generally compatible with each other, there are parts in each that don't work in the other.
Run your code, and post it as well as shell version, results and errors in here to be analysed and commented on.
