How to create .ini file using bash using template

Question

I am new to shell scripting. And trying to create a .ini file with following details. End result of .ini file:

[dev]
JDBC_URL = jdbc:h2:mem:mem_test;MODE=Oracle
JDBC_USERNAME =
JDBC_PASSWORD =

SERVICE_ENDPOINT = http://localhost:8080/Central/api/AppService

[qa]
JDBC_URL = jdbc:oracle:thin:@qa-oracle:1521:qa
JDBC_USERNAME = qauser
JDBC_PASSWORD = qapass

SERVICE_ENDPOINT = http://qa-services/Central/api/AppService

[prod]
JDBC_URL = jdbc:oracle:thin:@prod-oracle:1521:prod
JDBC_USERNAME = scott
JDBC_PASSWORD = tiger

SERVICE_ENDPOINT = http://prod-services/Central/api/AppService

@Cyrus, i already had a look on this, but it doesn't solve my purpose as i am looking for creating multi section file with common fields in each seaction. And by section i mean dev, qa, prod. — Srishti

@BleedCode, why don't you crate a property file eg--> JDBC_URL, JDBC_USERNAME,JDBC_pass and URL etc and then provide values there, you could easily use while or awk to read that file and could create these kind of files then, let me know on same if that is what you are looking for? — RavinderSingh13

Let's say you create following property Input_file.

cat Input_file
dev,bla-bla-bla,user_singh,singh,http://chumma.com
qa,bla-bla-bla,user_singh1,http://chumma1.com

It's value are in format of environment,JDBC_URL,user,pass,service_point Then following may help you on same.

while IFS=, read environment jdbc_url user pass service
do
   echo -e "[" $environment "]\nJDBC_URL = $jdbc_url\nJDBC_USERNAME = $user\nJDBC_PASSWORD = $pass\nSERVICE_ENDPOINT = $service"
done < "Input_file"

But echo won't prints the value in properties file. It prints on console.

@BleedCode, you mean you need to create a single output file or multiple output files?

Srishti Over a year ago

One template file using which one properties file should be created with above content which i provided in example.

@BleedCode: Replace "Input_file" with "Input_file" > "properties.ini" to redirect stdout to a file.

Srishti Over a year ago

@RavinderSingh13 in bash we have a template for creating properties file. For more understanding go through this: Create new file from templates with bash script". So my question is same but i need a template with multiple sections.
