[ aws . s3api ]



This operation is useful to determine if a bucket exists and you have permission to access it.

See also: AWS API Documentation


--bucket <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--bucket (string)

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.


The following command verifies access to a bucket named my-bucket:

aws s3api head-bucket --bucket my-bucket

If the bucket exists and you have access to it, no output is returned. Otherwise, an error message will be shown. For example:

A client error (404) occurred when calling the HeadBucket operation: Not Found
