Awk printing each line in file seperatly - awk

Question

I am making a script that takes a list of zones records and values and puts it in a DNS server.
The formatting for the wanted output is just for ansible, the problem is i get that i can't operate on each line seperatly with awk.
What it does is when i don't mention a NR it prints all the items in the same line.
When i mention an NR it prints either nothing or only the specified NR (Ie only if i do NR==1 it will print the first line)
My objective is to iterate on all lines and print them in the format i want with newline after end of line.
bash_script
#! /bin/bash
read -p "File: " file
zone=`awk 'NR==1 { print $2}' ${file}`
echo "${zone}:" >> /etc/ansible/roles/create_dns/defaults/main/${zone}.yml
lines=`wc -l < ${file}`
for line_num in $(seq 1 $lines)
do
echo $line_num
echo `awk 'NR==$line_num {print " - { zone: \x27" $2"\x27, record: \x27" $1"\x27, value: \x27" $3"\x27 }\\n"}' ${file}` >> /etc/ansible/roles/create_dns/defaults/main/${zone}.yml
done
$file
ansible ben.com 10.0.0.10
test ben.com 10.0.0.110
example ben.com 10.0.0.120
Wanted output:
ben.com:
- { zone: 'ben.com', record: 'ansible', value: '10.0.0.10' }
- { zone: 'ben.com', record: 'test', value: '10.0.0.110' }
- { zone: 'ben.com', record: 'example', value: '10.0.0.120' }
Output i get:
ben.com:

You can use this single awk for this:
read -p "File: " file
awk '{printf "\t- { zone: \047%s\047, record: \047%s\047, value: \047%s\047 }\n", $2, $1, $3 > $2}' "$file"
cat ben.com
- { zone: 'ben.com', record: 'ansible', value: '10.0.0.10' }
- { zone: 'ben.com', record: 'test', value: '10.0.0.110' }
- { zone: 'ben.com', record: 'example', value: '10.0.0.120' }```

With your shown samples, please try following solution. This is a Generic solution, on basis of, you could give a number of column names in BEGIN section of this program under split section, but this is considering that you want to add strings(eg: zone, record etc) before each field/column values. IN case your number of strings are lesser than number of fields/columns in Input_file then you can change condition from i<=NF too as per your need, to fetch how many columns you want to get.
read -p "File: " file
awk -v s1='\047' 'BEGIN{OFS=", ";split("zone:,record:,value:",headings,",")} {for(i=1;i<=NF;i++){$i=headings[i]" " s1 $i s1};$0=" - { " $0" }"} 1' "$file"
Adding a non one liner form of solution here:
awk -v s1="'" '
BEGIN{
OFS=", "
split("zone:,record:,value:",headings,",")
}
{
for(i=1;i<=NF;i++){
$i=headings[i]" " s1 $i s1
}
$0=" - { " $0" }"
}
