Common Desktop Environment: Desktop KornShell User's Guide

Preface

The Desktop KornShell User's Guide provides the information you need to create Motif applications with KornShell (kshell) scripts. In addition to the basic information you'll need to get started, several example scripts of increasing complexity are described. Throughout this guide the term dtksh means the Desktop KornShell.

Who Should Use This Guide

This guide is intended for programmers who want a quick and easy means of creating Motif applications, but don't have the time, knowledge, or inclination to use the C programming language. A good understanding of kshell programming, Motif, the Xt Intrinsics, and, to a lesser extent, Xlib is needed. An understanding of C would also be helpful.

How This Guide Is Organized

Chapter 1, Introduction to Desktop KornShell describes the basic information you need to begin writing Motif applications in dtksh scripts.

Chapter 2, A Sample Script describes two simple dtksh scripts. The first script creates a push button widget within a bulletin board widget. The second script expands the first by adding a callback for the push button.

Chapter 3, Advanced Topics describes more advanced topics pertaining to dtksh scripts.

Chapter 4, A Complex Script describes a much more complex script than either of the ones described in Chapter 2. This script creates a graphic interface to the find command.

Appendix A, dtksh Commands lists all the dtksh commands.

Appendix B, dtksh Convenience Functions contains man pages for commands or functions that are not documented elsewhere.

Appendix C, The script_find Script contains the complete listing of the complex script described in Chapter 4.
