📚 PERL PROGRAMMING TOPICS
• Getting Started with Perl
Understand what Perl is where it is used how to install it configure a development environment and run your first script.

• Variables and Data Types
Learn about scalars numbers strings undefined values operators expressions interpolation and basic Perl syntax.

• Arrays Hashes and References
Work with arrays hashes lists references and nested structures to store organize and access information.

• Strings and Regular Expressions
Study string operations splitting joining pattern matching substitutions captures and regular expressions for search validation and text transformation.

• Conditions and Loops
Understand if unless while until for foreach loop labels and control statements used to manage program flow.

• Subroutines and Scope
Create reusable functions pass arguments return values and manage variable scope with my local and state.

• Files Directories and Input/Output
Learn to open read write append and close files. Explore filehandles directories standard input standard output and formatted text.

• Modules and CPAN
Understand Perl packages modules namespaces CPAN installation reusable libraries and coding conventions.

• Database and Web Integration
