We can also see in the S3 console that the new bucket has been created in the specified region.

Move a local file to the specified bucket

The following mv command moves a single file to a specified bucket and key.

aws s3 mv test.txt s3://mybucket/test2.txt

The following rm command deletes a single s3 object:

aws s3 rm s3://mybucket/test2.txt

The following rb command removes a bucket. In this example, the user's bucket is mybucket. Note that the bucket must be empty in order to remove:
