The Perl Programming course is a comprehensive course that explains the Perl programming language, from basic through advanced syntax. This course is aimed at a wide range of people - programmers, system administrators, web authors, and operators. It explains how to use the Perl programming language to write quick yet powerful scripts to take advantage of Perl's system administration capabilities and issue Perl commands.

who can benefit

Students who can benefit from this course are system administrators and web administrators, although Perl is a language for everyone. The course is taught on the UNIX platform (Solaris Operating Environment), however the material is suitable for any operating system (for example MSDOS, VMS, and so on).

prerequisites

To succeed fully in this course, students should be able to:

	Use basic UNIX commands such as rm, cp, man, more, mkdir, ps, and chmod (or be able to learn these quickly during the course)
	Create and edit text files in vi or another available text editor
	Exposure to any other programming language (C, C++, BASIC, Fortran, Java, Pascal, Shell...) and shell programming skills (Bourne/Korn) are a large advantage, although not essential

skills gained

Upon completion of this course, students should be able to:

	Write scripts that create and change scalar variables
	Use control structures to branch or loop
	Create and change array variables
	Create and change hash variables
	Read files supplied on the command line, and search the files for specific text patterns
	Execute regular expression tests, and recognize backwards referencing.
	Read and write files and system processes using file handles
	Create, remove, and change directory and file properties
	Create Perl subroutines, packages, and modules and use public modules
	Create real-world administration scripts
