If you find yourself with a customer requesting to know where all the domains associated with a cpanel account are pointing to or are migrating accounts, you can do the following:
#for each in `ls /var/cpanel/users/*`; do grep DNS $each >> domains.txt; done;
#sed -i 's:.*DNS.*\=::gi' domains.txt ;
#for each in `cat domains.txt`; do echo "doing a dig on $each"; dig $each | grep -E "^$each.*\b(A|CNAME).*\..*\..*" ; echo ""; done;
The output will be something similar to;
doing a dig on cavemantech.net
cavemantech.net. 13970 IN A 68.180.131.16
doing a dig on cave.cavemantech.net
cave.cavemantech.net. 13970 IN A 68.180.131.16
doing a dig on training.cavemantech.net
training.cavemantech.net. 13970 IN A 68.180.131.16
doing a dig on wordpress.cavemantech.net
wordpress.cavemantech.net. 13970 IN A 68.180.131.16
doing a dig on roundcube.cavemantech.net
roundcube.cavemantech.net. 13970 IN A 68.180.131.16
doing a dig on confluence.cavemantech.net
doing a dig on dino.cavemantech.net
dino.cavemantech.net. 13970 IN A 68.180.131.16
Also if you need multiple queries for a specific record:
#dig example.com ns another.com ns
or if all records are needed:
#dig example.com any another.com any
which returns non-label (resource records) RRs for both domains
# dig example.com another.com any
which returns A (resource records) RR for 1st and non-label (resource records) RRs for 2nd domain
# dig example.com any another.com
which returns non-label (resource records) RRs for 1st and A (resource records) RR for 2nd
