Intermediate Perl

Course Description

This course takes people who use Perl a little and turns them into Perl programmers. Building on the foundations of our Introduction to Perl course it will take your Perl programming ability to the next level. This course will enable you to use Perl to tackle just about any problem.

The course can be run over one day in lecture style or over two days including practical exercises.

Intended Audience

This course will be useful to anyone who has used Perl occasionally, but who now wants to improve their knowledge of Perl in order to become a competent Perl programmer. In order to get the most out of this course, you should be comfortable writing simple Perl programs using loops, subroutines and CPAN modules. Our Introduction to Perl course provides an ideal background for this course, but we recommend a couple of months of using the skills learned from that course before attending this one.
