LOAD = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB = The low-level unit activation state, values depend on unit type.
123 loaded units listed. Pass --all to see loaded but inactive units, too.
To show all installed unit files use 'systemctl list-unit-files'.
</programlisting>
The header and the last unit of a given type are underlined if the
terminal supports that. A colored dot is shown next to services which
were masked, not found, or otherwise failed.</para>
<para>The LOAD column shows the load state, one of
<constant>loaded</constant>, <constant>not-found</constant>,
<constant>stub</constant>, <constant>error</constant>,
<constant>merged</constant>, <constant>masked</constant>. The ACTIVE
columns shows the general unit state, one of <constant>active</constant>,
<constant>reloading</constant>, <constant>inactive</constant>,
<constant>failed</constant>, <constant>activating</constant>,
<constant>deactivating</constant>. The SUB column shows the
unit-type-specific detailed state of the unit, possible values vary by
unit type. The list of possible LOAD, ACTIVE, and SUB states is not
constant and new systemd releases may both add and remove values.
<programlisting>systemctl --state=help</programlisting> command maybe be
used to display the current set of possible values.</para>
<para>This is the default command.</para>
