The 'service' command does not exit until the service receives a signal.
This is typically run from launchd (Mac), systemd or init (Linux), etc.

If 'set' is followed by a 16-digit hex number it will get/set network config
options. Otherwise it will get/set service options. Run with no arguments to
see all options.

An identity can be specified as a file or directly. This is auto-detected.

Most commands require a secret token to permit control of a running
service. The CLI will automatically try to read this token from the
authtoken.secret file in the service's working directory and then from a
file called .zerotierauth in the user's home directory. The -t option can
be used to explicitly specify a location.`)
