Sometimes we do not want to kill the zone files along with the accounts,To perform this action First of all get a list of all the accounts and put that list into a file called /root/acctlist:
grep -v 'root\|#' /etc/trueuserowners | grep resellerusername | cut -d: -f1 > /root/acctlist
Note: Please replace resellerusername with the reseller’s username.
Now if you have a list of users, you can run the following command to terminate the accounts but still keep the DNS:
for i in `cat /root/acctlist` ;do /usr/local/cpanel/scripts/killacct $i --killdns=n --force ;done
