Bash : Adding Input Prefix To Dig Output

when I do , 

$dig axfr @ns2.3u.net weclapp.com

I get output result as,

; <<>> DiG 9.8.1-P1 <<>> axfr @ns2.3u.net weclapp.com
; (1 server found)
;; global options: +cmd
weclapp.com.        300 IN  SOA ns1.3u.net. ops.3u.net. 2015052602 21600 3600 604800 180

Now i would like to add each output line with a number read from a file. I did,

#Input.txt
1,weclapp.com,ns2.3u.net

#test.sh
while IFS=, read -r n d s;do 
      printf "$n,%s\n" $(dig axfr @"$s" "$d")
done < Input.txt

#d is domain , #s is name server ,#n is number from the input file.

When i run it $sh tesh.sh,I get output as.

1,......

Can some one suggest on how to achieve adding input number (n ) to the following dig command output ?

You can modify your script like this:

while IFS=, read -r n d s;do
   dig axfr @"$s" "$d" | sed "s/^\(.\)/$n,\1/"
done < Input.txt

sed will skip adding $n, on empty lines but will prefix $n, on all other lines.

Output:

1,; <<>> DiG 9.8.3-P1 <<>> axfr @ns2.3u.net weclapp.com
1,; (1 server found)
1,;; global options: +cmd
1,weclapp.com.      300 IN  SOA ns1.3u.net. ops.3u.net. 2015052602 21600 3600 604800 180

1,weclapp.com.      300 IN  NS  ns1.3u.net.
1,weclapp.com.      300 IN  NS  ns2.3u.net.
