I am attempting to learn shell programming using o'rielly book "Learning the Korn Shell".
I am finding it pretty difficult to do since the only access I have to unix boxes are running version 99 of ksh.
The book utilizes ksh93 and there appear to be many differences. I can't even follow along with the examples.
I am running into problems with setting compound variables and etc.
My question is can anyone recommend a book/tutorial dealing with ksh99? Or at least some type of bridge between the two that will allow me to utilize the book?
