Perl, a rich computer programming language, runs on more than 100 computer platforms for a wide range of applications, from mainframes to portable devices, from rapid prototyping to large-scale scalable development.
Perl was originally designed by Larry Wall and published on December 18, 1987. It is now Perl 6, updated on December 25, 2015.
Perl borrowed features from C, sed, AWk, shell scripting languages, and many other programming languages, the most important of which were regular expression integration and the huge third-party code base CPAN. In short, Perl is as powerful as C and as convenient as scripting description languages like AWk and SED. Perl enthusiasts call it “a fantastic scripting language with all the language features” and “the ace tool in Unix.”
Perl is commonly called “Practical Extraction and Report Language,” and you may also see “Perl,” with all the letters in lower case. Generally, “Perl,” with a capital P, refers to the language itself, while “Perl,” with a lowercase P, refers to the interpreter the program runs on.

The introduction
Since Larry Wall released Perl1.0 in 1987, the number of users has increased dramatically, and more and more programmers and software developers have been involved in Perl development. From its inception as a high-level language for writing portable tools in a cross-platform environment, Perl is widely recognized as an industrial-scale powerful tool that can be used anywhere to get your job done. Perl’s predecessor was a Unix system administration tool used for countless small tasks. After gradually developed into a powerful programming language, used for Web programming, database processing, XML processing and system management; It’s designed to do all of this while still being able to handle small, everyday tasks. Perl is particularly well suited for systems administration and Web programming. Has been used in virtually all Unix(including Linux) bundled together as a standard component, as well as for Microsoft Windows and almost all operating systems. Perl is widely used. The basic information
Perl was originally designed by Larry Wall, who published it on December 18, 1987. Perl borrows features from C, sed, AWk, shell scripting languages, and many other programming languages. The most important features are the built-in regular expression capabilities and the huge third-party code base CPAN. Perl is known as a “Practical Extraction and Reporting Language.” It’s a term, not just a shorthand, and Perl’s creator, Larry Wall, came up with the first one, but quickly expanded to the second. That’s why Perl doesn’t have all uppercase letters. There’s no need to argue about which is right. Larry agrees with both. The programming language Perl is a programming language designed and continuously updated and maintained by Larry Wall. Perl has the power and flexibility of a high-level language such as C. In fact, as you’ll see, many of its features are borrowed from THE C language. Perl, like scripting languages, doesn’t need a compiler or linker to run your code; you just write a program and tell Perl to run it. This means that Perl is ideal for quick solutions to small programming problems and for creating prototypes for large events to test potential solutions. Perl provides all the functionality of scripting languages such as SED and AWk, and a lot more than they do. Perl also supports sed to Perl and awk to Perl translators. In short, Perl is as powerful as C and as convenient as scripting description languages like AWk and SED. The characteristics of
Perl interpreters are open source, free software, and you don’t have to worry about the cost of Perl. Perl runs on most operating systems and can be easily migrated to different operating systems. Perl is a language that gets the job done. From the beginning, Perl was designed as a language that could simplify simple tasks without losing the ability to handle difficult problems. It can easily manipulate numbers, text, files and directories, computers and networks, especially program languages. The language should make it easy to run external programs and scan their output for things of interest. And it should be easy to hand things you’re interested in to other programs for special processing. Of course, the language should also be easy to compile and run portable on any modern operating system.
