wget can be used to get a single file from a website, or to download the entire site if you know how. Here some examples of using wget.

To get a single file from a website, and save it using it's default name, use:

  wget http://www.cameraangle.co.uk/index.php
  
  This will download the file index.php from wwww.cameraangle.co.uk

To get a single file from a website, and save it using a new name, use:

  wget http://www.cameraangle.co.uk/index.php -O index.txt
  
  This will download the file index.php from wwww.cameraangle.co.uk and save it as index.txt

This does depend on the site supporting resuming.
