Course Description

This hands on course provides a comprehensive introduction to writing Korn and Bash shell scripts. Besides covering fundamental syntax for program flow control, variable assignment and substitution, I/O control, and mathematical expressions, it emphasizes the powerful features of these shells, including built-in string operators, variable typesetting/conversion, functions, and coprocess communication and control. The creative use of standard UNIX and Linux utilities within scripts to solve problems is stressed throughout. The Korn Shell and Bash Shell programming course is designed for the administrators and programmers who are developing, testing, or integrating software on UNIX or Linux, as well as for advanced UNIX or Linux users. Both the commonalities and differences between the Korn and Bash shells are examined, and students will have the opportunity to learn from examples coded in both shells. Comprehensive hands on exercises are integrated throughout this Unix Shell programming course to reinforce learning and develop real competency.

Students who are not already familiar with fundamental UNIX syntax and common UNIX commands should take the 5-day UNIX/Linux Fundamentals and Shell Scripting course rather than this 3-day course.

Course Prerequisites

Familiarity with the UNIX file system and commands is required to learn Korn Shell and Bash Shell. Students who are not familiar with the UNIX file system and commands should instead register for the course UNIX/Linux Fundamentals and Shell Scripting.
