systemd-ac-power

OPTIONS

Description

systemd-ac-power 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 ConditionACPower= (see systemd.unit(5)).

Options

The following options are understood:

-v; --verbose
Show result as text instead of just returning success or failure.

--low
Instead of showing AC power state, show low battery state. In this case, will return zero if all batteries are currently discharging and below 5% of maximum charge. Returns non-zero otherwise.

Exit status

On success (running on AC power), 0 is returned, a non-zero failure code otherwise.
