AIX Essentials

Length: 3 Days

Prerequisite: Basic computer skills                     

Recommendation Statement:
Student should have basic computer skills: able to use a computer monitor, keyboard and mouse.

Course Description:
This course teaches basic and advanced topics in AIX and is equivalent to the IBM AN100 course.  The course 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 AIX 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 korn shell.

The classroom labs are run in a real-world Solaris environment where students have access to IBM Power servers running the AIX operating system.  Lab exercises 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 AIX classroom environment with an expert instructor, you will learn AIX concepts and commands from both the desktop GUI environment and the command line. You will receive professional tips and techniques that will help you build your AIX confidence and skills.


Upon completion of this course, you should be able to:

  • Log in and log out of an AIX system
  • Understand AIX Korn shell concepts
  • Compose command-line strings to perform functions
