rb - Remove buckets
gsutil rb [-f] gs://<bucket_name>...
The rb command deletes a bucket. Buckets must be empty before you can delete them.
Be certain you want to delete a bucket before you do so, as once it is deleted the name becomes available and another user may create a bucket with that name. (But see also "DOMAIN NAMED BUCKETS" under "gsutil help naming" for help carving out parts of the bucket name space.)
|-f||Continues silently (without printing error messages) despite errors when removing buckets. If some buckets couldn't be removed, gsutil's exit status will be non-zero even if this flag is set.|
