Perl is one of the most popular text processing languages in the world. It allows you to create extremely efficient text parsers for all sorts of applications.

This interactive course will help you get up to speed on Perl, starting off with basic concepts like loops, strings, and arrays. You'll build your way up to more complex topics like data structures and packages.

No background knowledge is needed. Anyone willing to understand the principles and syntax of Perl to use it in the future will find this course useful.

Learn Perl from Scratch


`Perl` was originally developed by **Larry Wall** in **1987** as a *general-purpose* Unix scripting language to make text processing easier. Before **Perl**, almost all text processing on Unix-like systems was done with a conglomeration of tools that included `sed` and `awk`, the various shell programming languages, and `C` programs.

> Perl stands for **P**ractical **E**xtraction and **R**eport **L**anguage.

`Awk` is a lot slower than `sed`. Perl reliably outperforms the `sed` and `awk` and is also very useful for the computation of regular expressions. 



## Perl as a language

`Perl` is a family of *high-level*, *general-purpose*, *interpreted* and  *dynamic programming* languages. The languages in this family include Perl **5** and Perl **6**. 

It is intended to be practical as it is *easy to use* and *efficient*. It supports both **procedural** and **object-oriented** programming and has great built-in support for *text processing* and has an impressive collection of third-party modules.

## Perl's use in industry

`Perl` is used in many fields and has helped the industry over the years. List of fields in which `Perl` is commonly used is given below:

* System Administration
* Web Development
* Network Programming
* GUI Development
