Perl 1: Introduction to Perl

In this course, you will learn the basics of scripting with Perl. Perl has long been considered “the duct tape of the Internet.”  It is used to do everything from building web pages to creating back-end applications and administrative scripts.  Countless programs have been written in Perl over the years.

Upon completion of this course, you will be able to:

  • Create and run Perl programs using basic scalars, arithmetic, conditional statements, and interpolation.
  • Implement and manipulate strings, functions, operators, lists, loops, and arrays.
  • Format output and list content.
  • Map data with hashes.
  • Perform basic Unix commands.
  • Aggregate and sort data using subroutines.
  • Read external files in Perl.

From beginning to end, you will learn by doing your own Perl-based projects and submitting them for instructor feedback.  These projects, as well as the final project, will add to your portfolio and contribute to certificate completion.  besides a browser and internet connection, all software is provided online by the O’Reilly School of Technology.

This course counts toward both the Perl Programming Certificate Series and the Open Source Programming Certificate Series.

Prerequisites: Experience using a web browser and email.  This course is meant for the beginning or intermediate student.
