Perl Training Course

Overview

This course introduces users, programmers and system administrators to the popular interpreted language called Perl (Practical Extraction and Report Language).

Although Perl is hailed as the system administrator's language and is the standard de facto language for writing dynamic web pages, this practical course will be useful for anyone working with UNIX text files, databases and processes.

Objectives
