This script simply add the Tor repository to your Ubuntu GNU/Linux distribution, and setup this Tor as a relay node.
Try:
$ curl https://github.com/PeterDaveHello/ubuntu-tor-simply-setup/raw/master/setup.sh -Lo- | sudo bash
or
$ wget https://github.com/PeterDaveHello/ubuntu-tor-simply-setup/raw/master/setup.sh -O- | sudo bash
By default, we'll use 21 port to run tor service, the bandwidth rate and the burst will be limited by 1MB and 2MB, see setup.sh and /etc/tor/torrc for more details.
