Perl is a high-level, general-purpose programming language that was originally developed for text manipulation and now used for a wide range of tasks, including web development, system administration, and network programming. Perl was initially designed for text processing and manipulation, and it excels at tasks involving regular expressions and string manipulation. It has powerful features for handling text data, making it popular for tasks like parsing log files and extracting information from text.The name "Perl" originally stood for "Practical Extraction and Reporting Language," reflecting its initial focus on text processing tasks. However, over time, it has evolved into a general-purpose programming language.Perl has robust support for regular expressions, allowing developers to perform complex pattern matching and manipulation of strings with ease. This is one of the language's strengths, especially in tasks that involve searching, matching, and transforming textual data.

1. Introduction to Perl
Programming Language
-Practical Extraction and Reporting Language

2. Introduction:
 Perl is a versatile programming language developed by
Larry Wall in the late 1980s. It is designed for text
processing, system administration, and various scripting
tasks
 It efficiently handles text manipulation, making it a popular
choice for diverse applications

3. History:
 Evolution from Perl 1 to Perl 5.
 Perl's journey from a text-processing language to a
general-purpose programming language.
 Perl 1, 2, 3, 4, and the transformative Perl 5.

4. Basic Syntax Of Perl Program
 Perl is a general purpose, high level interpreted and
dynamic programming language.
 Perl is a lot similar to C syntactically and is easy for the
users who have knowledge of C, C++.
 Like other Programming Languages, Perl also follows a
basic syntax for writing programs for applications and
software or writing a simple Perl program.

5. Our First Perl Program:

6. Perl Language is used for:

7.  System Administration: Widely used for automating
system tasks.
 Text Processing: Known for powerful regular
expression support.
 Web Development: Used for server-side scripting and
CGI programming.
 Bioinformatics: Applied in handling biological data.
 Diverse Usage: Flexible for various applications.

8. Advantages:
 Flexibility: Supports multiple programming paradigms.
 CPAN: Rich ecosystem of modules for easy extension.
 Text Processing: Exceptional for handling and
manipulating text.
 Community Support: Active community and resources.

9. Disadvantages:
 Learning Curve: "Some find the syntax unconventional."
 Performance: "May not be as fast as some compiled
languages."
 Stringent Practices: "Lack of enforced discipline can lead
to less maintainable code."

10. Conclusion:
 Perl has proven itself to be a dynamic and adaptable
programming language since its inception in the late
1980s. Originally designed for text processing, Perl has
evolved into a robust and versatile tool embraced across
various domains.
 In today's programming landscape, Perl remains a
valuable asset, offering a unique blend of features that
cater to both traditional and emerging application
domains.
