Following is the script we are running.

for x in `cat /root/domain | cut -d: -f1` ; do echo "ns1 14400 IN A $x" >> /var/named/$x.db ; done

The script is inserting the domain but instead of the domain name (Domain1.com), we need the IP (192.0.2.55) to be inserted.

ns1 14400 IN A Domain1.example

We are looking for the below-mentioned data.

ns1 14400 IN A 192.0.2.55

File in content: (domain)

• Domain1.example 192.0.2.55


• Domain2.example 198.51.100.2

EDIT #1

We have around 500 domains and trying to insert A records to the domains with specific IPs.

Example:

• domain1.example 192.0.2.33


• domain2.example 198.51.100.44


• domain3.example 203.0.113.44

The below mentioned script assigns the required records to the domains individually.

$ for x in domain1.com; do echo "ns1 14400 IN A 192.0.2.126" >> /var/named/$x.db; done

We have a file containing the domains and the IPs and we would like to have a script which would assign the records from that file itself in bulk (See the above mentioned example).

Problem is with delimiter : in cut, which does not exist.

Try,

for x in `awk 'print $2' /root/domain ` ; do echo "ns1 14400 IN A $x" >> /var/named/$x.db ; done

This can be done with pure bash:

while read a x; do [ -n "$x" ] && echo "ns1 14400 IN A $x" >>/var/named/$x.db ; done <file

• 
  read a x: assign the first word to $a and the second word to $x.


• 
  [ -n "$x" ]: if $x is not empty


• 
  echo "..." >> append to the desired file.


• 
  <file: file is the input file with the domains and IPs.
