where to find the help document?

[Ruby Newbee]

Hello,

How to find ruby's help document?
for example, I want to know what's the difference between two
functions of "p" and "print", but don't know where to search.

Thanks.

These are described in the Pickaxe book which is distributed with Ruby.
Also you can use ri.

Here are the core docs http://ruby-doc.org/core/

and here the standard library docs http://ruby-doc.org/stdlib/

Or have a look at http://www.ruby-doc.org .

Thanks all.
So, is there a convenient way to check the usage of a function?
like unix's `man printf` or Perl's perldoc -f print

Regards.
