Hands-On KornShell93 Programming is a self-paced tutorial that introduces you to the essentials of KornShell programming. Based almost entirely on short, focused examples that demonstrate central concepts and effective programming techniques, it will quickly bring you up to speed. The book reflects the newest version of KornShell, KSH93. It also provides coverage of significant developments, such as CGI programming with KornShell, and offers an in-depth look at KornShell string handling. Humorously written, the book makes it easy to learn KornShell essentials, including data types, math, pattern matching, conditions, loops, menus, command-line arguments, functions, start-up scripts, I/O, strings, variables, background processes, and CGI scripts. Highlighted "Beware" sections will warn you of potential pitfalls and keep you on the track to learning effective KornShell programming. CD-ROM contains the U/WIN package of popular UNIX utilities.
Korn Shell Programming by Example is a straight-forward, nuts and bolts book that will become a standard in the libraries of Unix administrators everywhere because of its real-life examples, progressive style, and lack of unnecessary fluff. Based on the Korn shell, it is an essential reference for administrators on how to program their system, and it is also beneficial for those new to Unix who need to know how to automate their system. Most of all, Korn Shell Programming by Example teaches and arms readers with the ability to solve problems they might encounter. Shows system administrators how to program using Korn Shell 93 and automate many of their daily tasks. The author discusses building scripts with variables and functions, manipulating data and files, controlling the flow of logic within a script, and using filters to isolate particular data. An appendix documents many commands that are useful in writing scripts.
This is a Second Edition of the best-selling guide to the KornShell command and programming language by the original inventors of the language. It provides a specification for the KornShell language, tutorial material for those new to ksh (the program that implements the KornShell language), and a comprehensive reference for all ksh users. Covers major new additions to the KornShell language ksh93 (including command completion and a key binding mechanism); provides tutorials for both of the functions of ksh (as an interactive command language, and as a programming language); contains numerous examples illustrating the features of ksh; and features a Quick Reference summary of the KornShell language with page references to the book. For both new users with little shell experience, and for experienced computer users who are familiar with ksh and/or other shells. A tutorial that describes the functions of ksh and summarizes KornShell.
Beginners may be wondering, "Is this book too hard for me?" No, probably not. Programmers experienced in various languages, though not in the KornShell, are probably wondering, "Is this book too wimpy for me?" No, probably not. To help guide both kinds of readers through the book, the author marked certain sections as being more appropriate for one group or the other. Beginners don't need an explanation of traps and experienced programmers already know what loops are. This book will teach you the following: introduces the KornShell and its features; contains some simple KornShell scripts to get you started; discusses data types; shows you how to do simple math; illustrates pattern matching; Explains how to evaluate conditions; shows you how to set up loops; describes how to create simple menus; explains how to evaluate command line arguments; illustrates functions; examines input and output; focuses on string manipulation.
The Korn shell is an interactive command and scripting language for accessing Unix and other computer systems. As a complete and high-level programming language in itself, it's been a favorite since it was developed in the mid 1980s by David G. Korn at AT&T Bell Laboratories. Knowing how to use it is an essential skill for serious Unix users. Learning the Korn Shell shows you how to use the Korn shell as a user interface and as a programming environment. Learning the Korn Shell is the key to gaining control of the Korn shell and becoming adept at using it as an interactive command and scripting language. Prior programming experience is not required in order to understand the chapters on basic shell programming. Readers will learn how to write many applications more easily and quickly than with other high-level languages. In addition, readers will also learn about Unix utilities and the way the Unix operating system works in general.
