ecclectic, interpreted language with deep roots in Unix. It was originally
written by Larry Wall, creator of other Unix staples such as patch and rn,
to help with system administration tasks. Because many of its variables are
$, Perl often looks like an
awk program or even a Bourne shell
script. Like all appearances, this too can be deceiving. Perl is a complete
programming language that supports both structured and object oriented
programming. Getting started with Perl is easy, since many of the Bourne shell
tricks you’ve seen will work (after a fashion) under Perl. As your knowledge
grows, you’ll find that Perl will help you scratch increasingly obscure itches.
Because Perl has been ported to many different platforms, it brings a Unix-like
API to whichever operating system is hosting it. Perl makes cross-platform
programming a reality.
The complete guide to Perl is O’Reilly’s Programming Perl, a book that weighs in at over 1500 pages. Therefore, only the barest of essentials can be presented here to help you identify your Perl installation, tinker with existing scripts, and install new modules. Luckily, Perl always comes with documentation that can be accessed through the perldoc (Section 41.10) system.
