Inhaltsangabe

Learning the Korn Shell is a thorough introduction to UNIX's newest and most powerful command interpreter. Like its predecessors, the C shell and the Bourne shell, the Korn shell is both an interactive environment and a programming language. This book describes both facets of the Korn shell's personality: how to use it for issuing commands and how to use it for writing powerful, efficient shell scripts. If you have put off learning shell programming, or if you've only dabbled in it, this book gives you the tools to get serious! It explains thoroughly all of the Korn shell's important programming features; it shows how to solve real-world programming problems simply and efficiently. Likewise, if you are an experienced Bourne shell programmer, this book will show you the Korn shell's significant new features and how to use them effectively. Although the Korn shell runs virtually all Bourne shell scripts correctly, reworking your scripts can make them significantly faster. At the same time, you can learn one of UNIX's most powerful command execution environments. The Korn shell provides command history editing, aliases, and other convenient interactive features. You can easily go back to your previous commands, modify them, and re-issue them, using commands modeled after the Emacs and vi editors. You'll also learn how to use environment variables and options to customize the shell's behavior. As a bonus, Learning the Korn Shell develops one extended programming example: a shell script debugger, written in the shell itself! It's the only program we know of its type; it's an elegant and practical tool that you'll want to use when developing your own shell programs.
