In systemd, the System V init concept of runlevels is replaced by the concept of targets. In a service file, e.g. bluetooth.service, in the install section, there will be a line like

WantedBy= multi-user.target

This means that when the target, multi-user, becomes active, the service, bluetooth in my example, will be started.

I am writing a program which needs to list every service's target. So I am trying to program finding it. Of course, my program could go to the /lib/systemd/system directory and parsing bluetooth.service to get the target, but is there some command I could give that would simply print out the target for a given service?

I did call forth the daemon but regardless of the paraphernalia and incantations used it wouldn't be persuaded into emitting a response suitable for parsing.

Thanks for trying.
