Overview
Perl is an interpreted programming language that is optimised for text processing. As such, it is well suited for generating reports based on data extracted from files.
Perl is available on all major operating systems including Unix, Linux, Windows, OS/2 and Mac/OS. The language interpreter is freely available, as is a vast amount of pre-written code.
Objectives
On successful completion of this course, participants will be able to:
- Write and execute Perl programs
- Write and use Perl subroutines
- Locate and use Perl modules
- Understand Perl's powerful regular expressions
- Use Perl to manipulate files and directories
- Navigate the extensive Perl documentation
Audience
This course is for system administrators who wish to process data and log files and require a language that enables powerful and flexible report-generation programs to be written quickly and easily.
This course is also an essential stepping stone for programmers and analysts who wish to use Perl for the CGI and object-oriented programming tasks covered in the Advanced Perl course.
Prerequisites
Participants are expected to be familiar with at least one other programming language. Those with C, C++, Java and/or Unix shell programming experience will recognise many syntactical similarities.
