Tips and Tricks of wget
When you ever need to download a pdf, jpg, png or any other type of picture or file from the web, you can just right-click on the link and choose to save it on your hard disk. This is possible for one or even up to five files, but more than that.
wget is a GNU program, which is used a lot in Linux, it can download pages, and files from the internet directly to your computer.
If you do not have it installed you can install on:
Debian or Ubuntu
sudo apt-get install wget
Download a single file
Download the whole site recursively
wget -r http://www.site.com
Download all files of a specific type: (pdf and jpg for example)
