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.
