sitefaqlet SiteDocClan  <h1>Where is Perl function foo() documented?</h1> An excellent repository of Perl documentation exists at [http://perldoc.perl.org/]. That's your one-stop shop. Also, [szabgab] has created this nice [http://www.szabgab.com/articles/perlindex.html|comprehensive perl index]. Your local installation of Perl comes with a full set of documentation on the Perl language and the perl execution environment. (This surprises a lot of people new to Perl.) On UNIX and UNIX-like systems (such as Linux), it's all available via the <code>perldoc</code> command. For example, <code>perldoc perlfunc</code> on UNIXy systems should give you the answer to the title question. On other OSes, Perl provides the same documentation in various forms — for example, in HTML — and with only a little searching under perl's installation directory, you should be able to find everything you need for basic questions. If you want to link to documentation for a function, either in a node or in the chatterbox, you can do it like this: <tt>[doc://foo]</tt> where foo is the function name in question. For example, <c>[doc://time]</c> -> [doc://time]. (Note that this also works for built-in perl variables, e.g. <c>[doc://@ARGV]</c>) If you want to jump immediately to such documentation in your browser, it's quite easy: simply type <tt>doc://foo</tt> (no square brackets) in the Search box at the top of any page. (To do a general search of the documentation at perldoc.perl.org, type <tt>perldoc://</tt> rather than <tt>doc://</tt>.) If you happen to be viewing a PerlMonks node which contains code (such as entries in the [id://1747] or [id://1967]), and you happen to have your [id://590090|Function Nodelet] enabled, that nodelet will contain links to the documentation for every function used in the code displayed on the node. <h4>Old On-site Docs</h4> If you don't mind looking at an older version of the Perl documentation, there are a couple of handy ways: For browsing, you can visit our dusty old [id://148].  This has an index of all the perl docs, including, for example, the Perl FAQ. If you want info on a specific function or topic, you can type its name in the Search box at the top of any page. This will take you directly to the corresponding page in the [id://148]. <hr/>Back to the [PerlMonks FAQ]
