wget(1) is a command line utility that will download files from a specified URL. It's useful for retrieving entire web sites for offline viewing, or for a more safer download of files from HTTP or FTP servers instead of Netscape. The basic syntax is:
$ wget <url> |
You can also pass options. For example, this will download the Slackware web site:
$ wget --recursive http://www.slackware.com |
wget will create a www.slackware.com directory and store the files in there, just as the site does.
wget can also download files from FTP sites; just specify an FTP URL instead of an HTTP one.
wget has many more options, which make it nice for site specific scripts (web site mirroring and so forth). The man page should be consulted for more information.
