I have environment variables
POSTGRES_USER=dbuser
POSTGRES_PASS=dbpasswd
POSTGRES_DBNAME=db
POSTGRES_HOST=123.123.123.123
POSTGRES_PORT=5432
I want to use them in bash script to declare a variable
#!/usr/bin/env bash
DATABASE_URL="postgres://$POSTGRES_USER:$POSTGRES_PASS@$POSTGRES_HOST:$POSTGRES_PORT/$POSTGRES_DBNAME"
How do I properly import my environment variables directly to my bash parameter DATABASE_URL?
