Export variables defined in another file

Question

The list of variables change constantly and modifying it on my end

Answer 1

Are you looking for the '.' command (also spelled 'source' in bash):

source foo.sh

Since you need to export them to the environment as well, you may need to do a little extra work:

while read -r line; do
    export "$line"
done < foo.sh
