prox_enable_path=`find /sys/devices/ -name 'prox_enable'`

if [ -z "$1" ]; then
     echo "0" > $prox_enable_path
else
     echo "1" > $prox_enable_path
fi

Save it as /use/sbin/proximity_disable.sh or /use/bin/proximity_disable.sh, note however that you need to login as root (devel-su) to use the script. Don't forget to chmod the script to add execution rights.
