Nameservers changed for all sites on one of my Plesk servers and I now have to modify all the NS records. Rather than spending the rest of my life doing the point and click shuffle I was trying to use the dns.sh script from ftp://download1.sw-soft.com/Plesk/Plesk7.5/Doc/plesk-7.5r-sdk-html/docs/cu/unix/ch08.html - but the documentation might as well have been in Russian. dns.sh command <domain_name> [-a -ip | -ns -nameserver | -mx -mailexchanger -priority | -cname -canonical | -ptr -subnet | -txt -domain ] Logically I'd expect something like dns.sh -d mydomain.com -ns myoldnameserver.com to delete an old nameserver entry but it complains about missing -nameserver. Adding that just gives another error. Maybe one of the Plesk gurus can clarify the syntax (and fix the documentation) ?
