Download one html page with all needed graphics and linked pdf/zip files

Try:

wget -r -np -k -p http://www.site.com/dir/page.html

The args (see man wget) are:

• r Recurse into links, retrieving those pages too (this has a default max depth of 5, can be set with -l).
• np Never enter a parent directory (i.e., don't follow a "home" link and mirror the whole site; this will prevent going above ccc in your example).
• k Convert links relative to local copy.
• p Get page-requisites like stylesheets (this is an exception to the np rule).

If I remember correctly, wget will create a directory named after the domain and put everything in there, but just in case try it from an empty PWD.

First of all, you should check with the website operator that this an acceptable use of their service. After that, you can do something like this:

wget -pk example.com

-p gets the requisites to view the page (the Javascript, CSS, etc). -k converts the links on the page to those that can be used for local viewing.

From man wget:

-p, --page-requisites

This option causes Wget to download all the files that are necessary to properly display a given HTML page. This includes such things as inlined images, sounds, and referenced stylesheets.

[...]

-k, --convert-links

After the download is complete, convert the links in the document to make them suitable for local viewing. This affects not only the visible hyperlinks, but any part of the document that links to external content, such as embedded images, links to style sheets, hyperlinks to non-HTML content, etc.
