Advanced Perl programming — a 3–day course
Synopsis
A course in Advanced Perl programming for those with a basic knowledge of
the language and a desire to extend their skills.
Please Note: This Perl training course outline provides a selection
of advanced skills in multi-purpose Perl programming rather than merely
specialist applications of the language. In practice, most purchasers of our
advanced Perl courses tend to require a combination of generic and specialist
skills. For that reason, we typically ask them to talk to our Perl consultants
about building a course combining some of the course modules outlined here with
other specialist modules from our complete
listing of Perl training course modules.
On the other hand, if you need an off-the-shelf specialist Perl course,
please consider our Perl for system
administration and our Perl for web
development courses.
Suitable for
- Perl programmers who want or need to use the Perl language well
in a variety of contexts.
- Developers who want to optimise their Perl; taking advantage of the
language's native productivity tools and techniques, rather than holding on to
inefficient methods imported from other languages.
Prerequisites
- Considerable Perl programming experience
Delivery
This is a hands-on practical workshop based around the coding of real world
solutions to real world problems.
This advanced Perl training course is run primarily as an in-house/on-site
course for company groups.
From time to time, we take bookings from individuals on publicly scheduled
versions of the course. Because of the relatively small numbers of people who
are ready for advanced perl programming, we tend to accumulate a list of
interested individuals before announcing a particular date.
Please contact us at training@gbdirect.co.uk to arrange
delivery of this course for your company or to register an interest in an
individual place on a public presentation of this course. N.B. Please state
clearly, which one of these two options applies to you.
