Yes, you can do that from the AWS CLI, with the mv command. Let me give you the step by step process. I am assuming you already have created the S3 bucket and added few objects.
Steps to rename files:
- Download and install the AWS CLI tool
- Then use the command aws configure and provide the necessary details. Follow this documentation - AWS configure documentation
- Use this command directly or save it in a file and call it : aws s3 -recursive mv s3://bucketname/foldername/filename s3://bucketname/foldername/newfilename
- Provide the appropriate information in the bucketname, foldername and filename parts. Enter the newfilename which you want in the second part.
That's it! This should work.
