recommened you do this from within tmux since the steamcmd
utility creates its own repl
taken from here
$ sudo useradd -m steam
$ sudo apt update && sudo apt-get install lib32gcc1 -y
$ sudo su - steam
$ mkdir ~/Steam && cd ~/Steam
$ curl -sqL "https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz" | tar zxvf -
