This is a trick to load a .ENV file into the session and then evaluate a template file, replacing the variables in it
Raw
load-env-file-and-render-template.sh
# read the .env file into the current env
source <(sed -E -n 's/[^#]+/export &/ p' .env)
# we need to escape the $ as ${DOLLAR} in the template,
# so now we can replace it correctly
sudo cat stub.conf.template | DOLLAR='$' envsubst > "${NEW_TEMPLATE_NAME}.conf"
