I am wondering how I go about finding the user that is running tor when installed on ubuntu. The quote below says that tor should be running as a separate user. I have a relay setup and currently running. I am doing this so that I can setup tor-arm based upon the instructions given here: https://www.torproject.org/docs/tor-relay-debian.html.en#after
"The best approach for most users is to run your relay on Debian or Ubuntu using the system Tor package — the deb takes care of running Tor as a separate user, making sure it has enough file descriptors available, starting it at boot, and so on."
I used option 2 on the following page to complete the ubuntu install: https://www.torproject.org/docs/debian.html.en
