Course Description:

'' Students Will Learn:Language Syntax
Pattern Matching
Flow Control
Arrays & Hashes
I/O and File Manipulation
Subroutines

Description: This hands on Perl scripting class provides a thorough introduction to the Perl programming language, teaching attendees how to develop and maintain portable scripts useful for system management and data manipulation. Emphasis is placed on built-in subroutines that can be used to help conveniently build fast, portable and efficient scripts. Extensive hands on exercises provide practice in report creation, pattern matching, string manipulation, file I/O, command line processing, and debugging. Students are shown how to extend Perl’s basic functionality with packages and loadable modules. Attendees who also want an in-depth introduction to CGI Programming and the use of the Perl DBI module for database access should attend the five-day Perl Programming and CGI Scripting course instead.

Prerequisites: Prior scripting experience or knowledge of fundamental programming concepts.
