This document should also find use as a handy desk reference for some of the more common perl related questions.<\/p>\n<h4>The history of perl in 100 words or less<\/h4>\n<p>In the mid-1980s, <a href=\"https:\/\/en.wikipedia.org\/wiki\/Larry_Wall\">Larry Wall<\/a> was working as a<a href=\"https:\/\/en.wikipedia.org\/wiki\/System_administrator\"> sys-admin<\/a> and found that he needed to do a number of common, yet oddball functions over and over again. And he did not like any of the scripting languages that were around at the time, so he invented Perl. Version 1 was released circa 1987. A few changes have occurred between then and now. The current version of Perl has exceeded 5.8.3 and is a highly recommended upgrade.<\/p>\n<p>Perl 6 is on the drawing board as a fundamental rewrite of the language. It is not available yet, and probably will not be available for some time.<\/p>\n<p><b>Perl<\/b>\u00a0is a family of two\u00a0<a title=\"High-level programming language\" href=\"https:\/\/en.wikipedia.org\/wiki\/High-level_programming_language\">high-level<\/a>,\u00a0<a title=\"General-purpose programming language\" href=\"https:\/\/en.wikipedia.org\/wiki\/General-purpose_programming_language\">general-purpose<\/a>,\u00a0<a title=\"Interpreter (computing)\" href=\"https:\/\/en.wikipedia.org\/wiki\/Interpreter_(computing)\">interpreted<\/a>,\u00a0<a title=\"Dynamic programming language\" href=\"https:\/\/en.wikipedia.org\/wiki\/Dynamic_programming_language\">dynamic programming languages<\/a>. &#8220;Perl&#8221; refers to Perl 5, but from 2000 to 2019 it also referred to its redesigned &#8220;sister language&#8221;, Perl 6, before the latter&#8217;s name was officially changed to\u00a0<a title=\"Raku (programming language)\" href=\"https:\/\/en.wikipedia.org\/wiki\/Raku_(programming_language)\">Raku<\/a>\u00a0in October 2019.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><iframe style=\"width: 100%; height: 700px; border: none;\" src=\"https:\/\/online.visual-paradigm.com\/share\/book\/iperl-19jt0abmgm?enforceShowPromotionBar=true&amp;p=1\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n","protected":false},"featured_media":21975,"template":"","meta":{"_yoast_wpseo_title":"","_yoast_wpseo_metadesc":""},"product_brand":[],"product_cat":[357],"product_tag":[],"class_list":{"0":"post-21971","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-perl","8":"first","9":"instock","10":"shipping-taxable","11":"product-type-simple"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 -
