For months I've been using:
$ sudo systemctl start tor.service
but I just realized we can start tor by simply typing "tor" into a terminal. What's the proper/safest way to start and stop tor.service?
Normally the Tor service should be started/stopped with either
sudo systemctl start/stop tor.service or
sudo service tor start/stop.
Personally I've always used the
service command because it is simpler. I'm guessing things get a little more complicated when you run multiple Tor instances, but I have no experience with that.
Running Tor in a terminal runs Tor as your user, and binds it to that terminal window. Running as a service allows Tor to run in the background with the proper permissions.
