It supports HTTP, HTTPS, and FTP protocols, as well as 8retrieval through HTTP proxies. 9 10It can follow links in HTML pages and create local versions of remote 11web sites, fully recreating the directory structure of the original 12site. This is sometimes referred to as "recursive downloading." 13While doing that, Wget respects the Robot Exclusion Standard 14(/robots.txt). Wget can be instructed to convert the links in 15downloaded HTML files to the local files for offline viewing. 16 17Recursive downloading also works with FTP, where Wget can retrieves a 18hierarchy of directories and files. 19 20With both HTTP and FTP, Wget can check whether a remote file has 21changed on the server since the previous run, and only download the 22newer files. 23 24Wget has been designed for robustness over slow or unstable network 25connections; if a download fails due to a network problem, it will 26keep retrying until the whole file has been retrieved. If the server 27supports regetting, it will instruct the server to continue the 28download from where it left off. 29 30If you are behind a firewall that requires the use of a socks style 31gateway, you can get the socks library and compile wget with support 32for socks. 33 34Most of the features are configurable, either through command-line 35options, or via initialization file .wgetrc. Wget allows you to 36install a global startup file (/usr/local/etc/wgetrc by default) for 37site settings. 38 39Wget works under almost all Unix variants in use today and, unlike 40many of its historical predecessors, is written entirely in C, thus 41requiring no additional software, such as Perl. The external software 42it does work with, such as OpenSSL, is optional. As Wget uses the GNU 43Autoconf, it is easily built on and ported to new Unix-like systems. 44The installation procedure is described in the INSTALL file. 45 46As with other GNU software, the latest version of Wget can be found at 47the master GNU archive site ftp.gnu.org, and its mirrors.
