wget [options] [urls]

Perform non-interactive file downloads from the Web. wget works

in the background and can be used to set up and run a download

without the user having to remain logged on. wget supports

HTTP, HTTPS, FTP, as well as downloads through HTTP

proxies. wget uses a global startup file that you may find at /etc/

wgetrc or /usr/local/etc/wgetrc. In addition, users can define their

own $HOME/.wgetrc files.

Specify a comma-separated list of filename suffixes or patterns

to accept.

output to the file specified with -o or to wget-log ...
