You can use 'rb' option

If the bucket is not empty then use the --force flag
The following commands deletes the Bucket from S3
aws s3api delete-bucket --bucket "your-bucket-name" --region "your-region".
I am deleting S3 bucket from following command without any extra hustle of emptying it first
aws s3 rb s3://<BUCKATE-NAME> --force
for example
aws s3 rb s3://alok.guha.myversioningbucket --force
PS : Make sure you have programmatic access with policy "AmazonS3FullAccess"
