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.
