This script automatically looks for a .env file at the project root. The repo includes a .env.sample file. To use with your project, run cp node_modules/s3-sync-dir/.env.sample ./.env. The file includes the following config variables:


The script will fall back to the variables defined in the .env file, if not passed in explicitly as arguments.


The S3 bucket must be already created and grant write permissions to the owner of the AWS credentials.
