How to use AWS S3 CLI to dump files to stdout in BASH?

Question

I'm starting a bash script which will take a path in S3 (as specified to the ls command) and dump the contents of all of the file objects to stdout. Essentially I'd like to replicate cat /path/to/files/* except for S3, e.g. s3cat '/bucket/path/to/files/*'. My first inclination looking at the options is to use the cp command to a temporary file and then cat that. Has anyone tried this or similar or is there already a command I'm not finding which does it? Select the correct answer from above options

Answer 1

The contents of all the file objects have to be dumped to stdout Pass “-” for destination of aws s3 cp command to obtain this. For instance, $ aws s3 cp s3://mybucket/stream.txt What you're trying to do is something like this? :: #!/bin/bash BUCKET=your-bucket-name for key in `aws s3api list-objects --bucket $BUCKET --prefix bucket/path/to/files/ | jq -r '.Contents[].Key'` do echo $key aws s3 cp s3://$BUCKET/$key - | md5sum Done
