This course is designed to teach how to use Perl in everyday work – for example, in system administration for purposes of task automation. We focus on Perl’s main strength, namely, suitability for troubleshooting purposes, and to this end cover topics such as regular expressions, word processing, screenscraping, parsing web pages. The participants will also learn how to use the numerous useful Perl libraries, communicate with other processes or databases and communicate over the Internet.
We use Linux during this training; however, example of using Perl in Windows are also provided.
