Code sample

[SagarDamu]

Hi,
As I'm new to the concourse, now there is a scenario where I need to upload the file to the s3 bucket and pick a particular value from that file which is uploaded previously and use it in another job, if there is any sample code or syntax for uploading and downloading the file from s3 bucket through concourse it will be helpful, please provide if any sample code or syntax available. Thanks in advance.
