So if I am understanding the below should write each line in config to script.sh to be able to use as variables? By sourceing . $config the config into memory, that will not print the actual variables but the script will be able to use them, if I understand correctly. Thank you Smilie.

Code:
config=$1
. $config
echo "$@"
while read line; do
  echo "$line"
done <"$config" >script.sh
