# /usr/local/sbin/batterytest
# Baterry control
set restminutes=`/sbin/sysctl -n hw.acpi.battery.time`
set modus=`/sbin/sysctl -n hw.acpi.battery.state`
# does it have Power Supply connected?
if ( "${modus}" == "1" ) then
  # 7 Minutes?
  if ( "${restminutes}" < "7" ) then
    shutdown -p +2 "The Battery is empty! The Computer will shutdown after 2 Minutes!" &


# chown root /usr/local/sbin/batterytest
# chmod u+x /usr/local/sbin/batterytest
