How list Amazon S3 bucket contents by modified date?

Question

Most of the time it happens that we load files in a common S3 bucket due to which it becomes hard to figure out data in it.

How can I view objects uploaded on a part

Answer 1

This isn't a general solution, but can be helpful where your objects are named based on date - such as CloudTrail logs. For example, I wanted a list of objects created in June 2019.

aws s3api list-objects-v2 --bucket bucketname --prefix path/2019-06

This does the filtering on the server side. The downside of using the "query" parameter is it downloads a lot of data to filter on the client side. This means potentially a lot of API calls, which cost money, and additional data egress from AWS that you pay for.

Answer 2

Search on a given date

aws s3api list-objects-v2 --bucket BUCKET_NAME --query 'Contents[?contains(LastModified, `YYYY-MM-DD`)].Key'

Search from a certain date to today

aws s3api list-objects-v2 --bucket BUCKET_NAME  --query 'Contents[?LastModified>=`YYYY-MM-DD`].Key'

You can optionally remove the .Key from the end of the query to grab all metadata fields from the s3 objects
