Do you have a lot of domains and you want to quickly check if a domain exists on the server? Just run the shell command: grep yourdomain /etc/userdomains
root@web [~]# grep demo.plothost.com /etc/userdomains
demo.plothost.com: plothost
root@web [~]#In this case, the domain “demo.plothost.com” exists and it belongs to user “plothost”.
You may also want to know if the domain resolves to your server/IP. Use:
root@web [~]# dig demo.plothost.com
