I would love to have that feature in envsubst:

With a new flag (we could call it --curly-only) envsubst should only exchange
variables which use curly braces.

Example: "$foo ${bar}"

In this case $foo should not be changed, only "bar" should get substituted.

This would make it better for situations where you have a lot of dollar signs.
