I want to download the Chinese version of "Learn you a Haskell for Great Good" at http://learnyouahaskell-zh-tw.csie.org/, use this command:
wget -U mozilla --limit-rate=200k --no-clobber --convert-links --random-wait -r -p -E -e robots=off http://learnyouahaskell-zh-tw.csie.org/
where:
-U mozilla: pretends to be just like a browser Mozilla is looking at a page;
-r: recursive download all website, -p: download everything even pictures;
-E: gets the right extension of the file, without most html and other files have no extension;
-e robots=off: act like we are not a robot;
You can use "-l" option to specify the recursive depth. The default maximum depth is five layers.
