SYSPOWER(1) BSD General Commands Manual SYSPOWER(1)NAMEsyspower — display the remaining battery charge from the /sys interface
SYNOPSISsyspowerDESCRIPTION
The syspower utility parses the data in the Linux ACPI
/sys/class/power_supply tree and displays the remaining charge of the
battery both in the raw format read from the files and as a percentage of
the full charge.
Now, why in the world I would need to write this when I seem to have had
the acpi(1) tool right under my nose the whole time, is a question left
for better men than me to judge :)
RETURN VALUES
The syspower utility exits 0 on success, and >0 if an error occurs.
ENVIRONMENT
The syspower utility's operation is currently not directly affected by
its environment.
FILES
The syspower utility examines the /sys/class/power_supply/BAT* directo‐
ries and looks for the charge_now and charge_full files in each of them.
EXAMPLES
Display the current status of all the batteries that ACPI knows about:
