Unix Courses > AIX Basics Training Course

This course is designed for System Administrators and end-users that are new to the AIX Operating System. On this course delegates will learn how to accomplish basic tasks such as creating, organising and removing files, using electronic mail and text editors, printing and monitoring their processes. Delegates learn to accomplish these tasks through the command line interface.

For students studying towards IBM AIX certification, this introductory level course provides the pre-requisite knowledge for the AIX System and Network Administration courses.

Delegates should be familiar with basic information technology (IT) concepts and the role of an operating system. Experience of another operating system would also be beneficial.
