Perl Manual: Introduction

July 31, 2009 · Posted in Doc, Perl 

Perl is one of the most used and famed scripting language, it can be installed in almost all platforms and operating systems and it’s very versatile. It’s also free and there are a lot of websites with content Perl-related, CGI scripts for example. There are modules (or libraries) for the most varied programming tasks (mathematics functions, file compression/decompression, data encrypt, HTML and XML handling, networking, data base access, etc.).

The official web of Perl is http://www.perl.com and it has a lot of links to other useful information sources. Perl has a directory called CPAN (‘Comprehensive Perl Archive Network), with mirrors around the world, where you can find the main extension modules for this language.

Perl has the same virtues and flaws that the other scripting languages, like Python, Ruby, Tcl/Tk and, though less versatile, awk. The motto of Perl is “There’s more than one way to do it“, I believe it.
It’s a semi-interpreted/semi-compiled language, but we can consider it interpreted because don’t exist the intermediate compile and link stages, this make possible run the program just after write it.

In the next articles of this series I will try to explain the Perl basics for benefit from its efficiency and write speed.
