Course programme

This course is applicable to the Bourne shell and it's derivatives (e.g. the Korn shell and 'bash') on any Unix or Linux variant. Participants will gain an understanding of the the major concepts of Unix/Linux operation.

Effective use of shell scripts allow users and administrators to automate many complex tasks in Unix. In addition, the 'sed' and 'awk' programs enable powerful text processing scripts to be written. This course provides an in-depth coverage of scripting for all three programs.
