Options

--bucket (string)

The name of the bucket containing the object.

--if-match (string)

Return the object only if its entity tag (ETag) is the same as the one specified, otherwise return a 412 (precondition failed).

--if-modified-since (timestamp)

Return the object only if it has been modified since the specified time, otherwise return a 304 (not modified).

--if-none-match (string)

Return the object only if its entity tag (ETag) is different from the one specified, otherwise return a 304 (not modified).

--if-unmodified-since (timestamp)

Return the object only if it has not been modified since the specified time, otherwise return a 412 (precondition failed).

--key (string)

The object key.

--range (string)

Downloads the specified range bytes of an object. For more information about the HTTP Range header, see `http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.35 .

Note

Amazon S3 doesn't support retrieving multiple ranges of data per GET request.

--version-id (string)

VersionId used to reference a specific version of the object.

--sse-customer-algorithm (string)

Specifies the algorithm to use to when encrypting the object (for example, AES256).

--sse-customer-key (string)

Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side​-encryption​-customer-algorithm header.

--sse-customer-key-md5 (string)

Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

--request-payer (string)

Confirms that the requester knows that they will be charged for the request. Bucket owners need not specify this parameter in their requests. For information about downloading objects from requester pays buckets, see Downloading Objects in Requestor Pays Buckets in the Amazon S3 Developer Guide .

Possible values:

  • requester

--part-number (integer)

Part number of the object being read. This is a positive integer between 1 and 10,000. Effectively performs a 'ranged' HEAD request for the part specified. Useful querying about the size of the part and the number of parts in this object.

--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

To wait (pause running) until an object no longer exists

The following wait object-not-exists example pauses and continues only after it can confirm that the specified object (--key) in the specified bucket doesn't exist.

aws s3api wait object-not-exists \
    --bucket my-bucket \
    --key doc1.rtf

This command produces no output.

Output

None
