Bind : how to modify serial number of all your dns zone with sed

You can simply use the sed command to do this :

Go on your dns zone directory and :

<em>sed -i -e "s/2[0-9]\{9\}/yourserialnumber/g" path_to_your_dns_zone_files/*.hosts</em>

Example :

<em>sed -i -e "s/2[0-9]\{9\}/2012011901/g" /var/lib/named/var/named/master/*.hosts</em>

That’s done, you can just restart bind :)
