SYSPOWER(1) General Commands Manual SYSPOWER(1) NAME syspower -- display the remaining battery charge from the /sys interface 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 bat- tery 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* directories 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: syspower SEE ALSO acpi(1) HISTORY The syspower utility was written by Peter Pentchev in 2010. AUTHORS Peter Penchev <roam@ringlet.net> FreeBSD ports 15.quarterly December 26, 2010 SYSPOWER(1)
