UNIX KORN Shell Programming

Course ID

75300

Course Description

The Korn shell "language" is the JCL of the UNIX/Linux world and a lot more! It is widely used for automating routines (system administration, housekeeping, security scans) and for writing installation scripts. It is also useful for customizing UNIX tools or creating new tools; and for creating "user-friendly" and/or logical interfaces to other programs and tools. In this course, students learn to read, write, and debug Korn shell programs. Students learn how to use pipes, filters, I/O redirection, variable substitution, meta-characters, script tracing and debugging, shell functions, and signal handling. Exercises and lab sessions reinforce the learning objectives and provide participants the opportunity to gain practical hands-on experience.

Prerequisites

Successful completion of the "Fundamentals of UNIX" course, or equivalent experience. Ability to use the UNIX vi editor to write programs. Prior experience with some programming language would be helpful but is not required.

Audience

Programmers, system administrators, operations staff, and other users who are familiar with the fundamentals of the UNIX/Linux system environment and who would benefit from knowing and being able to apply advanced UNIX data processing, editing, and programming skills to their daily work.
