In addition to the basics of UNIX shell programming, _Learning the Korn Shell_ explains ksh string operations, co-processes, signals and signal handling, and one of the worst "dark corners" of shell programming, command-line interpretation. It covers new features like command history, which allows readers to recall and re-use previous commands conveniently, and built-in pattern matching, arithmetic evaluation, and condition evaluation, which allow them to write much more efficient shell scripts.

As an extended example of advanced shell programming, it contains kshdb, a Korn shell script that's a debugger for shell scripts. An Appendix summarizes the differences between the Korn shell and the standard Bourne shell, the IEEE 1003.2 POSIX Shell Standard, the Windowing Korn shell (wksh), and such public domain versions as pdksh and bash.
