There are plenty of file sharing utilities on the web. Some of them are CLI-based, and some of them are GUI-based. Some of them are free, and some of them are paid. When it comes to share or transfer large files from command line over Internet, there are only a few.
One of them is Transfer.sh. No, it isn’t a script, it is a website. It allows you to share files over Internet easily and quickly. You don’t need to install anything except cURL or wget. Most of the Linux distributions comes preinstalled with those utilities, so you don’t need to install anything, really.
