Goals

This course teaches tools and techniques used to write programs in Perl (Practical Extraction and Report Language). Perl is a multi-purpose scripting language widely used for systems administration tasks and for web-based applications development. It is available on Unix and Windows platforms. By the end of the course, participants will have a thorough understanding of basic and intermediate Perl concepts and will have been exposed to advanced Perl topics such as object-oriented programming and client/server programming.

After completing this course, participants will be able to:

• Create Perl-based software tools and prototypes
• Automate common tasks, including those that are difficult in shell scripts
• Manage files, databases, processes
• Apply Perl in Web CGI scripts and network applications

Audience

Experienced Unix or Windows users, systems administrators, and developers who wish to learn the Perl programming language.
