Perl is a high-level In computing, a high-level programming language is a programming language with strong abstraction from the details of the computer. In comparison to low-level programming languages, it may use natural language elements, be easier to use, or be more portable across platforms. Such languages hide the details of CPU operations such as memory access, general-purpose Array programming generalize operations on scalars to apply transparently to vectors, matrices, and higher dimensional arrays, interpreted In computer science, an interpreter normally means a computer program that executes, i.e. performs, instructions written in a programming language. While interpretation and compilation are the two principal means by which programming languages are implemented, these are not fully distinct categories, one of the reasons being that most interpreting, dynamic programming language Dynamic programming language is a term used broadly in computer science to describe a class of high-level programming languages that execute at runtime many common behaviors that other languages might perform during compilation, if at all. These behaviors could include extension of the program, by adding new code, by extending objects and. Perl was originally developed by Larry Wall Larry Wall is a programmer and author, most widely known for his creation of the Perl programming language in 1987, a linguist Linguistics is the scientific study of natural language. Linguistics encompasses a number of sub-fields. An important topical division is between the study of language structure and the study of meaning (semantics and pragmatics). Grammar encompasses morphology (the formation and composition of words), syntax (the rules that determine how words working as a systems administrator A system administrator, systems administrator, or sysadmin, is a person employed to maintain and operate a computer system and/or network. System administrators may be members of an information technology department for NASA The National Aeronautics and Space Administration is an agency of the United States government, responsible for the nation's public space program. NASA was established by the National Aeronautics and Space Act on July 29, 1958, replacing its predecessor, the National Advisory Committee for Aeronautics (NACA). The agency became operational on, in 1987, as a general-purpose Unix Unix is a computer operating system originally developed in 1969 by a group of AT&T employees at Bell Labs, including Ken Thompson, Dennis Ritchie, Brian Kernighan, Douglas McIlroy, and Joe Ossanna. Today the term Unix is used to describe any operating system that conforms to Unix standards, meaning the core operating system operates the same scripting language to make report processing easier.[1][2] Since then, it has undergone many changes and revisions and become widely popular amongst programmers. Larry Wall continues to oversee development of the core language, and its upcoming version, Perl 6 Perl 6 is a programming language specification. It serves as a major revision to Perl, introducing elements of many modern and historical languages. Perl 6 is intended to have many implementations. Backward compatibility with earlier versions of Perl is not a direct goal, though a compatibility mode is part of the specification. The design process.
Perl borrows features from other programming languages including C C is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system, shell scripting A shell script is a script written for the shell, or command line interpreter, of an operating system. It is often considered a simple domain-specific programming language. Typical operations performed by shell scripts include file manipulation, program execution, and printing text (sh The Bourne shell, or sh, was the default Unix shell of Unix Version 7, and replaced the Thompson shell, whose executable file had the same name, sh. It was developed by Stephen Bourne, of AT&T Bell Laboratories, and was released in 1977 in the Version 7 Unix release distributed to colleges and universities. It remains a popular default shell), AWK AWK is a programming language that is designed for processing text-based data, either in files or data streams, and was created at Bell Labs in the 1970s. The name AWK is derived from the family names of its authors — Alfred Aho, Peter Weinberger, and Brian Kernighan; however, it is not commonly pronounced as a string of separate letters but, and sed sed is a Unix utility that (a) parses text files and (b) implements a programming language which can apply textual transformations to such files. It reads input files line by line (sequentially), applying the operation which has been specified via the command line (or a sed script), and then outputs the line. It was developed from 1973 to 1974 as.[3] The language provides powerful text processing facilities without the arbitrary data length limits of many contemporary Unix tools,[4] facilitating easy manipulation of text files A text file is a kind of computer file that is structured as a sequence of lines. A text file exists within a computer file system. The end of a text file is often denoted by placing one or more special characters, known as an end-of-file marker, after the last line in a text file. It is also used for graphics programming Graphics are visual presentations on some surface, such as a wall, canvas, computer screen, paper, or stone to brand, inform, illustrate, or entertain. Examples are photographs, drawings, Line Art, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings, or other images. Graphics often combine text,, system administration A system administrator, systems administrator, or sysadmin, is a person employed to maintain and operate a computer system and/or network. System administrators may be members of an information technology department, network programming In computing, network programming, essentially identical to socket programming or client-server programming, involves writing computer programs that communicate with other programs across a computer network. The program or process initiating the communication is called a client process, and the program waiting for the communication to be initiated, applications that require database One way of classifying databases involves the type of content, for example: bibliographic, full-text, numeric, image. Other classification methods start from examining database models or database architectures: see below access and CGI programming The Common Gateway Interface is a standard protocol for interfacing external application software with an information server, commonly a web server on the Web The World Wide Web is a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia and navigate between them using hyperlinks. Using concepts from earlier hypertext systems, English physicist Tim Berners-Lee, now the Director of the. Perl is nicknamed "the Swiss Army chainsaw A Swiss Army knife , (French: Couteau suisse, German: Schweizer Offiziersmesser, Italian: Coltellino svizzero) is a brand of multi-function pocket knife or multi-tool. It originated in Ibach Schwyz, Switzerland in 1897. The term "Swiss Army knife" is a registered trademark owned by Wenger S.A. and Victorinox A.G., longtime suppliers of of programming languages" due to its flexibility and adaptability.[5]
