Learning the Korn Shell

This Nutshell Handbook® is a thorough introduction to the Korn shell, both as a user interface and as a programming language.The Korn shell, like the C and Bourne shells, is a program that interprets UNIX commands. It has many features that aren't found in other shells, including command history (the ability to recall and edit previous commands). The Korn shell is also faster; several of its features allow you to write programs that execute more quickly than their Bourne or C shell equivalents.T
