systemd-ac-power - Report whether we are connected to an external power source
systemd-ac-power [OPTIONS...]
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)).
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.
On success (running on AC power), 0 is returned, a non-zero failure code otherwise.
