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:
apt-get install wget
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:
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
