AFAIK, the files disappear each time the script is run:
umask 077
rm -f $TMPDIR/check.$$ $TMPDIR/checkoutput.$$
$TMPDIR/checkreport.$$
if [ -f $TMPDIR/check.$$ -o -f $TMPDIR/checkoutput.$$ -o -f
$TMPDIR/checkreport.$$ ]; then
echo "Log files exist in $TMPDIR directory that cannot be
removed. This
may be an attempt to spoof the log checker." \
| $MAIL -s "$HOSTNAME $DATE ACTIVE SYSTEM ATTACK!"
$SYSADMIN
exit 1
fi
