GNU Wget is a computer program that implements simple and
powerful content retrieval from web servers and is part of the
GNU Project. Its name is derived from World Wide Web and get,
connotative of its primary function. It currently supports
downloading via HTTP, HTTPS, and FTP protocols, the most popular
TCP/IP-based protocols used for web browsing. Its features
include recursive download, conversion of links for offline
viewing of local HTML, support for proxies, and much more. It
appeared in 1996, coinciding with the boom of popularity of the
web, causing its wide use among Unix users and distribution with
most major Linux distributions. Written in portable C, Wget can
be easily installed on any Unix-like system and has been ported
to many environments, including Mac OS X, Microsoft Windows,
OpenVMS and AmigaOS. Competitive tools include cURL. It has been
used as the basis for graphical programs such as Gwget for the
GNOME Desktop. Released under the terms of the GNU General
