<title>Description</title>
|
|
|
|
<para><command>systemd-ac-power</command> may be used to check whether the system
|
|
is running on AC power or not. By default it will simply return success (if we
|
|
can detect that we are running on AC power) or failure, with no output.
|
|
This can be useful for example to debug <varname>ConditionACPower=</varname> (see
|
|
<citerefentry><refentrytitle>systemd.unit</refentrytitle><manvolnum>5</manvolnum></citerefentry>).</para>
