Overview

IBM AIX Korn Shell Programming training course is designed to give delegates practical experience in developing and writing AIX shell scripts. Most of the built-in shell commands are introduced together with the main program control structures. This course is not suitable for C shell programmers

Audience

Programmers, administrators and support personnel who need to understand existing shell scripts, automate procedures and write their own utilities

The course assumes knowledge of the AIX Operating System to the level covered in the AIX Basics Course. Some programming experience may also prove advantageous

Skills Gained

The delegates will practise

  • Writing simple scripts to enhance basic command output
  • Using the various shell quoting mechanisms appropriately
  • Manipulating shell variables and user-defined variables in scripts
  • Implementing conditional execution facilities
  • Using the shell's built-in loop constructs where appropriate
  • Writing scripts to trap user interrupts
  • User defined Functions
  • Developing menu-driven shell scripts

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. It's a cost effective option.
