Name: Introduction to Unix and Shell Scripting
Course Code: GA100
Duration: 5

Scheduled Dates for GA100

This course provides an introduction to Unix, including operating system commands and creating and executing shell scripts. The Bourne shell is used in examples and exercises, so that the commands used will be as generic as possible among various shells. Students are also introduced briefly to the other major shells. The course is also appropriate as a refresher to those returning to Unix after a long time on other platforms, and would be helpful to those who have learned Unix on-the-job, and would now like to fill in gaps in their knowledge and deepen their understanding and skill. The course includes hands-on exercises to reinforce concepts and build skills.

Target Audience
This course is intended for programmers or others who need to use Unix as a data-processing platform or those who support Unix-based applications and users. The first part of the course, covering Unix basics, is also appropriate for end users who must use Unix to perform basic maintenance and navigation tasks, while the second part, shell scripting, is appropriate for programmers or system administrators who need to automate more complex tasks. Although the introductory and scripting material covered is appropriate for systems administrators, this course does not specifically cover system administration itself.
