getForwardedVariables.js
Implement and export as default a function that accepts the contents of the configuration file as a string, finds environment variables in it that need to be passed and returns them as a string in the format "name1=value1,name2=value2,name3=value3,...".
Environment variables in the configuration file are set by the environment command, after which there is a comma-separated list of variables in quotation marks.
environment="X_FORWARDED_MAIL=tirion@google.com,X_FORWARDED_HOME=/home/tirion,language=en"
Those variables that need to be forwarded start with the prefix X_FORWARDED_. Variable names in the output should be without this prefix. For example, if in the configuration file the variable is set like this: X_FORWARDED_HOME=/home/tirion, then in the output line it should look like this: "HOME=/home/tirion".
[program:prepare]
command=sudo -HEu tirion /bin/bash -c 'cd /usr/src/app && make prepare'
autorestart=false
environment="X_FORWARDED_MAIL=tirion@google.com,X_FORWARDED_HOME=/home/tirion,language=en"
[program:http_server]
command=sudo -HEu tirion /bin/bash -c 'cd /usr/src/app && make environment'
environment="key5=value5,X_FORWARDED_var3=value,key6=value6"
// Read the file contents and write it to the content constant. You don't need to implement this in your solution
const content = fs.readFileSync("s.conf", 'utf-8');
// Pass file contents to a function
const result = getForwardedVariables(content);
console.log(result); // => "MAIL=tirion@google.com,HOME=/home/tirion,var3=value"
