To download files through Linux Terminal, we can invoke the command wget.

Wget should be installed in all Linux distros. Otherwise, you may install it as follows:

Ubuntu/Debian

apt-get install wget

Fedora/CentOS

yum install wget

Wget will download the file and place it in your current navigated folder in the Terminal.

To download a single file from a webpage, issue the following command:

wget http://www.example.com/file.pdf

If you would like to download the entire website, include the -R (recursive) option:

wget -r http://www.example.com

Suppose you wanted to download all images from the website, include -R and -A options:

wget -r -A png,gif,jpg http://www.example.com
