shell programming

    This chapter looks at UNIX (and Linux) shell programming.

    You may wonder why a chpapter on shell scripting is in a programming book. And you may not even read this line because your professor probably has cut this entire chapter out of the version used in your class.

    There are actually several good reasons to include a chapter on shell scripting.

    The chapter can serve as background material so that a student new to UNIX (or Linux or Mac OS X) will be able to make effective use of the shell for work on programming assignements.

    There are actual classes in shell scipting, especially at junior colleges and community colleges.

    This chapter goes beyond the typical material in a shell scripting class and presents material related to either downloading and compiling existing software (including ports to new hardware and/or operating systems) or for preparing your own software for release via the internet.

This is a very worthy project that can benefit tens of millions of poor students at a very low cost (hundreds of dollars a month) and a banner ad for the sponsor could lead to millions of dollars of income.
