Assigning variable values on the fly in bash

Question

I have the below config file : OO_CONF.conf with the below contents:

appPackage_name = sqlncli
appPackage_version = 11.3.6538.0

Now i want to r

Answer 1

Use the declare built-in in bash with -g flag to make it globally available,

#!/bin/bash

while IFS=' = ' read -r  key value; do
    declare -g $key="$value"
done <OO_CONF.conf

printf "%s %s\n" "${appPackage_name}" "${appPackage_version}"

The idea is to set the IFS to = so to split the lines in the file to read the key and value pairs and then with declare we can create variables on the fly with the below syntax

declare -g <var-name>=<variable-value>
