Here are some handy wget commands
wget with username and password
In case a url requires simple web auth, one can use the following wget command.
$ wget --user user --password pass http://site.com/
wget – ignore certificate
$ wget --no-check-certificate https://site.com/
wget – download content to a specific file
$ wget http://site.com/ -O outfile
Continue getting a partially-downloaded file
This is useful when you want to finish up a download started by a previous instance of wget, or by another program.
$ wget -c http://site.com/ -O outfile
