read script properties from configuration file

Question

I have this batch script:

#target environment (this can be DEV/QA/PROD)
targetEnv=DEV 

url=get this from file name env_prop_${DEV}.ini
user=get this from file name env_prop_${DEV}.ini
password=get this from file name env_prop_${DEV}.ini

what i would like to do is extract all the the environment configuration into seperate files like:

config_DEV.ini   containing:
         url=dev1
         user=dev1
         password=pass1
config_QA.ini   containing:
         url=qa-server
         user=dev
         password=password
config_PROD.ini   containing:
         url=prod-server-01
         user=manager007
         password=*******

And then substitute the script variables according to the targetEnv
so for example if targetEnv is QA, variable url will be

       url=qa-server
       user=dev
       password=password

What have you tried so far, and what problems are you having? — cdarke, Jan 15 '18 at 22:26
i found a post with Perl substitution, but we don't have Perl installed. — JavaSheriff, Jan 15 '18 at 22:28
Please show the code that you have written so far, with any issues you might have. — cdarke, Jan 15 '18 at 22:30

You can do it this way:

url=$(awk -F "=" '/url/ {print $2}' config_$targetEnv.ini)
user=$(awk -F "=" '/user/ {print $2}' config_$targetEnv.ini)
password=$(awk -F "=" '/password/ {print $2}' config_$targetEnv.ini)

Or by sourcing your .ini, if it is formatted the way you wrote:

source config_$targetEnv.ini
