How to use neptune-export

Question

Can someone please list out a detailed stepwise process to export data from Neptune to S3(or local storage) in form of CSV. I followed the doc(which seems to be the only resource available online), but it is not very clear. TIA

The Neptune Export tool has many options that can be used to configure an export of both property graph and RDF data. The overall syntax of the command (if invoked via the command line) is:

NAME
        neptune-export.sh export-pg - Export property graph from Neptune to CSV
        or JSON.

SYNOPSIS
        neptune-export.sh export-pg
                [ --alb-endpoint <applicationLoadBalancerEndpoint> ]
                [ --approx-edge-count <approxEdgeCount> ]
                [ --approx-node-count <approxNodeCount> ]
                [ {-b | --batch-size} <batchSize> ]

                [ {-el | --edge-label} <edgeLabels>... ]
                [ --escape-csv-headers ] [ --escape-newline ]

                [ {-r | --range | --range-size} <rangeSize> ]
                [ {--region | --stream-region} <region> ]

There are detailed instructions at the GitHub page for the tool that describe the alternative ways to export data. https://github.com/awslabs/amazon-neptune-tools/tree/master/neptune-export
