Modifying/Adding in the DNS server entry using shell script
Dear Experts.

I need to add/modify the entries in the DNS server and this has to be achieved using shell script and below is the requirement, could you please let me know if a shell script can be written for this task?

Code:
1. Log in to primary DNS server
2. Check /etc/named.conf if zone is already created (grep –i 10.0.11 named.conf)
     Eg: if want to add server 10.0.11.13 in to DNS
zone "11.0.10.in-addr.arpa" in {
type master;
file "db.10.0.11";
};
3. If zone is already there go to /var/named
4. Then add server entry in file db.10.0.11
EG: 13 IN PTR servername.fg.net. And modify the serial number to yyyymmdd as below highlighted. 
Suppose if entry is made on 20th November enter the serial number as 20111120
root@PDNS1A101 # cat db.10.0.99
$TTL 5h
;SOA rec
99.0.10. in-addr.arpa. IN SOA PDNS1A101.fg.net. root.PDNS1A101.fg.net. ( 20090101; serial number ( you should change to 20111120)
10800; refresh every 3 hours
10800; retry every 3 hours
604800; expire after a week
86400) ; TTL of 1 day
; Name Servers
99.0.10.in-addr.arpa. IN NS PDNS1A101.fg.net.
;Pointer records for 10.0.99
11 IN PTR PSPROA167.fg.net.
12 IN PTR PSPROD055.fg.net.
5. Add entry in db.fg.net (please change serial number here also)
6. Restart dns service -- svcadm restart dns/server

To answer your question bluntly: Yes, it's doable. Give it a try and post your approach and - possibly erroneous - results, and we will try to help. Although the named files' structures are no secrets, input and ouput samples would help as well.

As a hint, look into the nsupdate command.
