What is envstore
envstore is:
envstore allows you to save environment variables into a separate store, list them, and reload them into the (other) shell again. It therefore provides a way to share them in cases where exporting to child processes is not feasible.
Included is envify, a shell script which loads the environment saved with envstore and then executes the command given to it.
