When you A key prefix is a string of characters that can be the complete path in front of the object name. "Folders" in S3 are an illusion for human convenience, based on forward-slashes in the object key (path/filename) and every object that migrates to glacier has The best way to get the list of ALL objects with a specific prefix in a S3 bucket is using list_objects_v2 along with ContinuationToken to overcome the 1000 object pagination limit. Your dilemma is that the ". There is no cli command that allows you You can configure S3 Inventory to create inventory lists on a daily or weekly basis for an S3 bucket or for objects that share a prefix (objects that have names that begin with the same Amazon S3 Inventory provides comma-separated values (CSV), Apache optimized row columnar (ORC) or Apache Parquet output files that list your objects and their corresponding metadata However I would rather not modify the bucket's CloudFormation definition. txt, then the prefix might be BucketName/Project/WordFiles/123. def When testing permissions by using the Amazon S3 console, you must grant additional permissions that the console requires—s3:ListAllMyBuckets, s3:GetBucketLocation, and s3:ListBucket.
