In this video, you'll learn how to get Perl documentation.
- [Voiceover] Perl includes a rich documentation system…called Perdoc, as part of the language package.…Perldoc is also available on the web at perldoc.perl.org,…and in fact this is probably…much more convenient for most people.…The entire documentation system is available here.…For example, if I wanted to know about the IO File module,…I can type in right here "IO::File",…just as I would declare it in my Perl script,…and here is the entire documentation for that module,…all of the methods, and how it all works.…
If I want to find out about a function,…like, for instance, "say" or "print",…I'll just type in "print" here,…and there is the print function.…And there is all the documentation for the print function.…Perldoc is also available from the command line…on any system with a properly installed Perl interpreter.…If you are familiar with the command line…and you like using it,…you can come out it here to the command line,…like I've done here,…and you can type "perldoc" and "IO File" like that,…and I get the documentation, just like a man page…
