The Bourne and Korn shell scripting should be good for scripting in Bash, as Bourne is the "original" commonly used shell and Bash and Korn are both syntactical extensions of it along generally the same themes. The C Shell also extends on the Bourne shell, but with a different syntax that is not compatible. Depending on your experience with shell scripting, this could be redundant or a "God-send" - my memories of the book are generally quite positive and that it was helpful to someone that had a C Shell background migrating to the Korn Shell (and which has still served me well with Bash.) -- Mark L.
