AIX Administration Essentials

This 3 day instructor led class is for students new to AIX, and it this class is your starting point to learn AIX Administration. This class starts at the beginner level and works into intermediate and advanced AIX commands and utilities. The student is
introduced to the AIX Korn shell, the command line and command syntax. Although
you will be exposed to the various windowing platforms available in AIX, this course teaches UNIX at “the command line level” to develop a thorough understanding of the AIX operating environment.

The student learns how to navigate the AIX file systems and how to work with files, directories and permissions. The student will learn how to use the AIX editors “ex” and “vi. “ Once the student is comfortable with basic AIX commands, they’ll move onto advanced power tools as well as how to customize the POSIX Korn shell.

The classroom labs are run in a real-world UNIX environment, are structured to allow you to learn by doing, and are developed to simulate “real world” situations. The hands-on labs progressively build your AIX knowledge and command skills in a clear and
concise manner.

Working in a controlled UNIX classroom environment with an expert instructor, you will learn AIX concepts and commands. You will receive professional tips and techniques that will help you build your AIX confidence and skills.

Recommendation Statement: Student should be able to use a computer monitor,
keyboard, mouse. Student needs to be able to input commands and control
characters from a keyboard.

 Log in and log out of AIX
