#!/bin/sh

if [ -e ${file} ];then
echo "this is not normal shutdown" >>/var/log/checkmessage

touch ${file}
fi

#!/bin/sh
file=/tmp/check
echo "this is normal shutdown and rm file" >>/var/log/checkmessage
rm -rf ${file}

ln -s /etc/rc.d/rc0.d/K01rm-file /etc/rc.d/init.d/rm-file.sh

#ll /etc/rc.d/rc0.d/

ln -s /etc/rc.d/rc6.d/K01rm-file /etc/rc.d/init.d/rm-file.sh
ln -s /etc/rc.d/rc3.d/S01touch-file /etc/rc.d/init.d/touch-file.sh
