If you ever need to download an entire website, perhaps for off-line viewing, wget can do the job — for example:
$ wget --recursive --no-clobber --page-requisites --html-extension --convert-links --restrict-file-names=windows --domains website.org --no-parent www.website.org/tutorials/html/
This command downloads the website www.website.org/tutorials/html/.
The options are:
--recursive: download the entire website--domains website.org: don't follow links outside website.org--no-parent: don't follow links outside the directory tutorials/html/--page-requisites: get all the elements that compose the page (images, css and so on)--html-extension: save files with the .html extension--convert-links: convert links so that they work locally, off-line--restrict-file-names=windows: modify filenames so that they will work in Windows as well--no-clobber: don't overwrite any existing files (used in case the download is interrupted and resumed).
