GNU Wget is a simple 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, 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.
# pacman -S wget
Configuration is performed in Template:Filename. Not only is the default configuration file well documented; altering it is seldom necessary. See the man page for more intricate options.
Normally, SSH is used to securely transfer files among a network. However, FTP is lighter on resources compared to scp and rsyncing over SSH. FTP is not as secure, but when transfering large amounts of data inside a firewall protected environment on CPU-bound systems, using FTP can prove beneficial.
wget ftp://root:email@example.com.X.Y//ifs/home/test/big/"*.tar" 3,562,035,200 74.4M/s in 47s
In this case, Wget transfered a 3.3 G file at 74.4MB/second rate.
In short, this procedure is:
- faster than ssh
- easily used by languages than can substitute string variables
- globbing capable
Wget uses the standard proxy environment variables. See: Proxy settings
To use the proxy authentication feature:
$ wget --proxy-user "DOMAIN\USER" --proxy-password "PASSWORD" URL
Proxies that use HTML authentication forms are not covered.
XferCommand = /usr/bin/wget --proxy-user "domain\user" --proxy-password="password" --passive-ftp -c -O %o %u
