The free, open-source wget command-line tool downloads content from the Web through a variety of protocols, including HTTP, secure HTTPS and FTP. Wget works in the background, even when you're not logged on, to run complicated or long download scripts without the need for user input. Wget also follows links and monitors FTP servers for updates. Wget isn't installed by default on most editions of Ubuntu, but you can add it with Ubuntu's apt-get utility.
Start a terminal session using an account that has root access on your system.
