This is a tool which downloads files via HTTP, HTTPS or FTP.
$ wget http://example.com
Use this if you do not want to check the https certificate. Sometimes you will get warnings such as:
WARNING: The certificate of `example.com' is not trusted. WARNING: The certificate of `example.com' hasn't got a known issuer.
and no data will be downloaded. To ignore the WARNING and download anyway, add the "no-check-certificate" option:
$ wget --no-check-certificate https://example.com
Proxy username. You will need to have the environment variable http_proxy set to the proxy server's URL. Note that http_proxy is in lowercase. You can specify the username and password in the URL, e.g. http://username:firstname.lastname@example.org:8080
