Course Description
The Practical Extraction Report Language (Perl) is a popular and portable scripting language used by anyone who needs to extract and manipulate data coming from text files, log files, databases, pipes etc. Perl is extremely powerful and fast, but easier to learn than languages like C and Java. The student will be able to produce working and meaningful Perl programs upon completion of this course.
 
Prerequisites
Students need to be familiar with the basics of programming and the use of a text editor. Although Perl can run on a number of operating systems, the course is normally taught in a UNIX/Linux or Windows environment.
