Hi Aioi, There's the already mentioned apm(8) (i.e. -l, -m options) or you could run something like this: #!/bin/sh sysctl -n hw.sensors.acpiac0.indicator0 \ hw.sensors.acpibat0.watthour0 \ hw.sensors.acpibat0.watthour3 | awk 'NR == 1 { ac = $1 } NR == 2 { full = $1 } NR == 3 { remaining = $1 } END { if ( ac == "On" ) state = "charging" else state = "discharging" printf("%s %d%s %s%s\n", "Remaining battery life is", remaining/full*100, "% and it is", state, "\.") }' Regards, Raf
