SYNOPSIS

syspower

DESCRIPTION

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

ENVIRONMENT

FILES
