| <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> |
