You're using the PGL adblock list - yes?
The proper way to do it would be something like

   get-pgl.sh
------------ begin cut here ------------
#!/bin/sh
# get the PGL adservers rpz zone
#   https://pgl.yoyo.org/adservers/serverlist.php?hostformat=rpz&showintro=1&mimetype=plaintext

url="https://pgl.yoyo.org/adservers/serverlist.php?hostformat=rpz&showintro=1&mimetype=plaintext"
fname="db.rpz-pgl"

umask 002
cd /etc/bind

ds=$(date "+%F")
echo "date suffix: ${ds}"

if [ -f "${fname}.${ds}" ]; then
   echo "OhNoes!!! ${fname}.${ds} already exists!"  >&2
   exit 1
fi

mv ${fname}  ${fname}.${ds}
stat=$?

if [ $stat -ne 0 ]; then
   echo "Oh Noes!! 'mv ${fname}  ${fname}.${ds}' failed!!?  ${stat}"  >&2
   exit 2
fi

wget --no-proxy -O ${fname} ${url}
stat=$?

if [ $stat -ne 0 ]; then
   echo "OhNoes!!! wget ${url} failed: ${stat}"  >&2
   exit 3
fi

dos2unix ${fname}
stat=$?

if [ $stat -ne 0 ]; then
   echo "OhNoes!!! dos2unix ${fname}  failed: ${stat}"  >&2
   exit 4
fi

------------  end  cut here ------------

then in your named.conf you'd have something like

  response-policy { zone "rpz.foo"; zone "rpz.bar"; zone "rpz.pgl"; }
     break-dnssec yes
     recursive-only no
     qname-wait-recurse no;

zone            "rpz.foo"     in { ... }
zone            "rpz.bar"     in { ... }
zone            "rpz.pgl"     in { type master; notify no; file
"/etc/bind/db.rpz-pgl"; };
