Here's a safer way to do this:

#!/bin/sh
ROOT=terp.umd.edu
TMPFILE=/tmp/ns.$$
DIG=/etc/dig
DBCACHE=/usr/local/dns/root.cache
#
# Look up root server information and store it in a temporary file.
#
$DIG @$ROOT . ns >$TMPFILE

#
# Move the new cache in place if it is not empty.
#
if test -s $TMPFILE
then
        mv $TMPFILE $DBCACHE
        #
        # Reload the nameserver
        #
        kill -HUP `/bin/cat /etc/named.pid`
else
        rm $TMPFILE
fi
