Perl - The Camel Symbol

Perl - Example Program. In Perl, the canonical "Hello world" program is: #!/usr/bin/perl print "Hello, world!\n"; The first line is the shebang, which tells the operating system where to find the Perl interpreter. The second line prints the string Hello, world! and a newline (like a person pressing 'Return' or 'Enter'). The shebang is the usual way to invoke the interpreter on Unix systems. Windows systems may rely on the shebang, or they may associate a .plSee also:

CPAN, the Comprehensive Perl Archive Network, is a collection of mirrored web sites that serve as a primary archive and distribution channel for Perl sources, distributions, documentation, scripts, and—especially—modules. It is commonly browsed with the search engine http://search.cpan.org/. There are currently over 8,800 modules available on CPAN, contributed by over 2,500 authors. Modules are available for a wide variety of tasks, including advanced mathematics, database connectivity, and networking. Essentially everything on CP ...

Perl was originally named "Pearl", after "the pearl of great price" of Matthew 13:46. Larry Wall wanted to give the language a short name with positive connotations; he claims that he looked at (and rejected) every three- and four-letter word in the dictionary. He also considered naming it after his wife Gloria. Wall discovered before the language's official release that there was already a programming language named PEARL and chan ...

At the 2000 Perl Conference, Jon Orwant made a case for a major new language initiative. This led to a decision to begin work on a redesign of the language, to be called Perl 6. Proposals for new language features were solicited from the Perl community at large, and over 300 RFCs were submitted. Larry Wall spent the next few years digesting the RFCs and synthesizing them into a coherent framework for Perl 6. He has presented his design for Perl 6 in a series of documents called apocalypses, which are numbered to correspond to chapters ...

The design of Perl can be understood as a response to three broad trends in the computer industry: falling hardware costs, rising labor costs, and improvements in compiler technology. Many earlier computer languages, such as Fortran and C, were designed to make efficient use of expensive computer hardware. In contrast, Perl is designed to make efficient use of expensive computer programmers. Perl has many features that ease the programmer's task at the expense of greater CPU and memory requirements. These include automatic memory management; dynamic typing; strings, lists, and hashes; regular expressions; intros ...

The perlintro(1) man page states: Perl is a general-purpose programming language originally developed for text manipulation and now used for a wide range of tasks including system administration, web development, network programming, GUI development, and more. The language is intended to be practical (easy to use, efficient, complete) rather than beautiful (tiny, elegant, minimal). Its major features are that it's easy to use, supports both procedural and object-oriented (OO) programming, has powerful built-in support for text processing, and has one of the world's most impressive collectio ...
