A. Audience

This course is for individuals who have completed "UNIX for Beginning Users" (or equivalent experience) and want to write UNIX BourneShell script files. A script file contains a sequence of UNIX commands which can be executed by entering one command. It is assumed that the student already has a good understanding of the UNIX operating system, be able to use a UNIX editor, and be familiar with a computer terminal or typewriter keyboard.

B. Course Objectives

Upon successful completion of this course the student will be able to: 1. Write moderately complex BourneShell scripts. 2. Make a BourneShell script executable. 3. Demonstrate how to use the following BourneShell commands: shift, exit, expr, test, if then, if then else, if then elif, for, while, until, and case. 4. Use the following BourneShell constructs: tracing mechanisms (for debugging), user variables, BourneShell variables, read-only variables, positional parameters, reading input to a BourneShell script, command substitution, comments, and exporting variables. In addition, test on numeric values, test on file type, and test on character strings are covered. 6. Create a ".profile" script to customize the user environment. 7. Use advanced features of File Transfer Protocol (FTP) 8. Compile source code into object and executable modules. 9. Optional: KornShell programming. This is of primary interest to programmers. 10. Convert VMS DCL command files to UNIX Shell.

C. Course Handout Conventions

There are several conventions used in this handout for consistency and easier interpretation: 1. Samples of actual terminal sessions are single-lined boxed. 2.
