GNU Wget (or just Wget, formerly Geturl) is a computer program that retrieves content from web servers, and is part of the GNU Project. Its name is derived from ''World Wide Web'' and ''get''. It supports downloading via HTTP, HTTPS, and FTP protocols. Its features include recursive download, conversion of links for offline viewing of local HTML, and support for proxies. 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 Microsoft Windows, Mac OS X, OpenVMS, HP-UX, MorphOS and AmigaOS. It has been used as the basis for graphical programs such as GWget for the GNOME Desktop. ==History== Wget descends from an earlier program named Geturl by the same author, the development of which commenced in late 1995. The name changed to ''Wget'' after the author became aware of an earlier Amiga program named GetURL, written by James Burton in AREXX.Wget filled a gap in the web-downloading software available in the mid-1990s. No single program could reliably download files via both HTTP and FTP. Existing programs either only supported FTP (such as NcFTP and (dl )) or were written in Perl, which was not yet ubiquitous. While Wget was inspired by features of some of the existing programs, it aimed to support both HTTP and FTP and to enable the users to build it using only the standard development tools found on every Unix system. At that time many Unix users struggled behind extremely slow university and dial-up Internet connections, leading to a growing need for a downloading agent that could deal with transient network failures without assistance from the human operator. In 2010 US Army intelligence analyst PFC Chelsea Manning used Wget to download the 250,000 U.S. diplomatic cables and 500,000 Army reports that came to be known as the Iraq War logs and Afghan War logs sent to Wikileaks. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Wget」の詳細全文を読む スポンサード リンク
