Pour créer le fichier de configuration, on peut s'appuyer sur les scripts suivants:

cd /var/lib/squidguard/db/blacklist/dest/
ls */usage | xargs grep -l black | xargs -n1 dirname | (
    while read list; do
	echo "dest $list {"
	if [ -f "$list/domains" ]; then
	    echo "  domainlist $list/domains"
	fi
	if [ -f "$list/urls" ]; then
	    echo "  urllist $list/urls"
	fi
	if [ -f "$list/expressions" ]; then
	    echo "  expressionlist $list/expressions"
	fi
	echo "}"
    done
)

echo $(ls */usage | xargs grep -l black | xargs -n1 dirname | while read list; do echo '!'$list; done)
