LOAD = unit definition was properly loaded.
ACTIVE = high-level unit activation state, i.e. generalization of SUB.
SUB = low-level unit activation state, values depend on unit type.

50 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
                          All are 
                        loaded active
