Ubuntu – How to download archive of ubuntu community documentation so that i can use it offline

Use wget -r -l 0 -np -e robots=off -U "Mozilla/5.0 (Windows NT x.y; rv:10.0) Gecko/20100101 Firefox/10.0" -k -p -R *action=* https://help.ubuntu.com/community in your target directory. @asutosh 's would hypothetically work, but one would incur robots.txt issues, extra pages downloaded, etc. I have tested this and it will download all HTML. If you want to get images, you may need to do a bit of tweaking.
