A quick script to add env variables to your heroku application. Following options are required:
  -h,  [--help]    | show this help text
  -f=, [--file=]   | env file path
Sample command: ./$(basename "$0") -f='.env'
"

# Reading input options
for i in "$@"; do
  case $i in
    -f=*|--file=*)
      FILE="${i#*=}"
    ;;

    -h*|--help*)
      printf "$usage"
      exit 0
    ;;

    *)
      # ignoring unknown option
    ;;
  esac
done

# Check if -f option is present
if [ -z $FILE ]
then
  echo -e "${YELLOW}--file${NC} ${RED}option missing${NC}. Use --help option to know the command\n"
  exit 1
fi

echo -e "\n${BLUE}---> Looking for your envs${NC}\n"

ENVS=""
while IFS='=' read key value; do
    # Check that the key is not empty and that it does not start with "#" to avoid comment
    if [[ ! -z "$key" && ! $key =~ ^#.* ]]; then
      echo -e "$key=$value"
      ENVS="$ENVS $key=$value"
    fi
done < "$FILE"

echo -e "\n${BLUE}---> Set all env to the following app ${NC}\n"

heroku apps:info

echo -e "\n${BLUE}---> Setting up the envs ${NC}\n"

heroku config:set $ENVS
