[ aws . s3api ]

head-bucket

Description

This operation is useful to determine if a bucket exists and you have permission to access it. The operation returns a 200 OK if the bucket exists and you have permission to access it. Otherwise, the operation might return responses such as 404 Not Found and 403 Forbidden .

To use this operation, you must have permissions to perform the s3:ListBucket action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources .

See 'aws help' for descriptions of global parameters.

Synopsis

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

Options

--bucket (string)

The bucket name.

--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. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--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.

See 'aws help' for descriptions of global parameters.

Examples

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

Output

None
