Students will immediately be able to use Perl to complete tasks in the real world.
Working within in an engaging, hands-on learning environment, guided by our expert web development, PHP practitioner, students will learn to:
Create a working script that gets input from the command line, the keyboard, or a file
Use arrays to store and process data from files
Create formatted reports
Use regular expressions
Use the appropriate types of variables and data structures
Refactor duplicate code into subroutines and modules
What is available in the standard library
Use shortcuts and defaults, and what they replace
This course is appropriate for anyone who wants to create applications or modules to automate and simplify common tasks with Perl.
