Perl Programming
Course Description
This course starts by introducing you to the basics of programming in the Perl environment. The full extent of what can be done with Perl is explored. You will enhance your command set and be capable of creating some extremely useful applications, not just local to your machine, but across the network, or with databases.
The course work is based around a 40/60 approach to lecture and hands on giving the attendee the chance to really work with the system and see its potential. Where possible, the practicals will use real world examples and useful starting code that can be integrated into new or existing projects.
If project work is a must then creating modules will help you maintain projects efficiently and allow multiple people to work on larger applications.

Who should attend?
Experienced system administrators, Programmers and Analysts intending to implement Perl programs, e.g. HTML generation, application control, and report generation, data manipulation, etc.
Pre-requisites
This course is intended for competent programmers in another structured language such as C, Basic, Unix Shell scripting, etc. This is a comprehensive course that moves quickly through the key topics required to gain a full understanding of the Perl Programming environment.
