NAME

systemd-ac-power - Report whether we are connected to an external power source

SYNOPSIS

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.

Added in version 253.

--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.

Added in version 254.

-h, --help

Print a short help text and exit.

--version

Print a short version string and exit.

EXIT STATUS

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