Perl is a script programming language with syntax similar to the C language. It is an older interpreted language that is open source and free to use. Perl was designed with ease of use in mind. Its efficient design enables developers to accomplish much with a small amount of code. Perl is easier to learn than structured languages like C and C++. Nonetheless, the language is used to create sophisticated programmes. Because of its good text manipulation capabilities and ability to deal with binary files, the language is frequently used to develop familiar gateway interface (CGI) programmes.

Design and Features of Perl
Perl includes standard Unix utilities like sed, awk, and tr. Because it is an interpreted language, it can run code and execute instructions without compiling the entire programme into machine language instructions.
On the other hand, Perl can be compiled into C code or cross-platform bytecode before execution. A Perl programme is almost as fast when compiled as a fully pre-compiled C language programme. Some servers, such as Apache, support a plugin that keeps Perl in memory at all times. This reduces compile time and speeds up CGI Perl script execution.
Easy to start
Perl is a high-level language. It is more similar to other popular programming languages such as C and C++, making it simple to learn for anyone.
Text-Processing
As the acronym "Reporting Language and Practical Extraction" suggests, Perl has strong text manipulation capabilities, allowing it to generate reports from various text files quickly. It can also convert files into different formats.

Contained Best Features
Perl incorporates features from other languages such as C, sed, awk, and sh, making it more valuable and productive.
System Administration
Perl makes system administration simple due to its support for multiple scripting languages. Instead of becoming dependent on various languages, use Perl to complete the entire system administration task. Despite this, Perl is also used in web programming, web automation, GUI programming, and other areas.
Web and Perl
Perl can be embedded in web servers to increase processing power, and it includes the DBI package, which makes web-database integration a breeze.
Advantages of Perl
- Perl supports cross-platform development and is compatible with mark-up languages such as HTML, XML, and others.
- It is instrumental in text manipulation, i.e. Regular Expression. It also has a socket capability.
- It is open-source and free software licensed under the Artistic and GNU General Public Licences (GPL).
- Because it is an embeddable language, it can be embedded in web and database servers.
- It supports over 25.000 open source modules from the CPAN (Comprehensive Perl Archive Network) that provide many powerful extensions to the standard library. For instance, XML processing, GUI (Graphical User Interface), and DI (Database Integration), among others.
