I am not a Linux expert and currently using a Fedora 23 Server (so only command line) with no FTP access for a project. I am used to install software directly in command line with prepared download commands, like - to state an example - the go-cd solution I currently use on my Fedora: https://docs.gocd.io/current/installation/install/server/linux.html
Now I have encountered a software that I want to install on my Fedora and I don't figure out how because the installation instruction does not state any download commands which suggests I have to download the package by clicking on a download button, unzip the package in some folder of my fedora server - a procedure that would only work if a.) I could paste the unzipped package through a FTP client, which does not work because I have no FTP access.
So is there a way to download any package only via command line? The software I want to download is this btw http://pmd.sourceforge.net/pmd-4.3/installing.html
