kfox / apply_environment_variables.sh
Created September 9, 2022 15:17
Apply environment variables to your current shell context, useful for when you SSH into a server and need your user to operate in the same context as a service already running as that user, e.g. Celery, etc.
eval $(xargs -0 -L1 -a /proc/1/environ | grep -E '^[A-Z].*' | sed -e 's/=/="/' -e 's/$/"/')
