In this Shell Programming training, students learn to read, write, and debug Korn shell scripts. Back at work they can greatly increase productivity by automating repetitive tasks (for themselves or others), and by creating specifically tailored utilities designed to meet their precise needs. Students will read and write many shell scripts in this class, which will additionally increase their overall UNIX knowledge and skills.

The course is intended for UNIX users, programmers, and system administrators.
