</img> When there is the need to download files like pictures, PDFs, or any other type of file, it can be done by right clicking on the link and choosing to save the given file, but that is tiring.
A better approach is to use wget
It is usually installed in all Linux distros, but if not we can install it.
Debian / Ubuntu
apt-get install wget
Fedora / CentOS
yum install wget
Now lets explore some of its features.
If there is the need to download a single page.
But if there is the need to download the entire site, use the recursive option.
wget -r http://www.site.com
Now what to do if only certain file types are needed? Use the -A option
To download only pdf and jpg use.
wget -r -A pdf,jpg http://www.site.com
Well now suppose that there is the need to follow external links, usually wget does not do this, here we can use -H option.
wget -r -H -A pdf,jpg http://www.site.com
This is a little bit dangerous as it could end up downloading a lot much files that the ones needed, so we could limit the sites to follow, we will use -D for this.
wget -r -H -A pdf,jpg -Dfiles.site.com http://www.site.com
By default wget will follow 5 levels when using -r option, we can change this behaviour with the -l option.
wget -r -l 2 http://www.site.com
This way only two levels depth will be followed.
