I'm no expert at Perl. There are a number of websites with tutorials on Perl (see the reference section), but I wanted to share my learning of Perl over the years. Therefore, this tutorial takes examples I had to solve or look up on the internet as I programmed in Perl and explains them. This is a continuous work in progress.
While this tutorial does contain a chapter named Introduction, I would strongly urge a beginner at Perl to go through at least one of the tutorials mentioned in the Reference section. Most of this tutorial contains practical examples for people already familiar with Perl or at least have some scripting background.
