NAME

s4cmd.py - Super Amazon S3 command line tool

SYNOPSIS

s4cmd.py [options]

DESCRIPTION

S4cmd is a command-line utility for accessing Amazon S3, inspired by s3cmd. It is intended as an alternative to s3cmd for enhanced performance and for large files, and with a number of additional features and fixes. In general, it strives to be compatible with the most common usage scenarios for s3cmd. It does not offer exact drop-in compatibility, due to a number of corner cases where different behavior seems preferable, or for bugfixes.

Super S3 command line tool. Version 2.1.0

--API-ACL=ACL

The canned ACL to apply to the object.

--API-CacheControl=CACHECONTROL

Specifies caching behavior along the request/reply chain.

--API-ContentDisposition=CONTENTDISPOSITION

Specifies presentational information for the object.

--API-ContentEncoding=CONTENTENCODING

Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.

--API-ContentLanguage=CONTENTLANGUAGE

The language the content is in.

--API-ContentMD5=CONTENTMD5

The base64-encoded 128-bit MD5 digest of the part data.

--API-ContentType=CONTENTTYPE

A standard MIME type describing the format of the object data.

--API-CopySourceIfMatch=COPYSOURCEIFMATCH

Copies the object if its entity tag (ETag) matches the specified tag.

--API-CopySourceIfModifiedSince=COPYSOURCEIFMODIFIEDSINCE

Copies the object if it has been modified since the specified time.

--API-CopySourceIfNoneMatch=COPYSOURCEIFNONEMATCH

Copies the object if its entity tag (ETag) is different than the specified ETag.

--API-CopySourceIfUnmodifiedSince=COPYSOURCEIFUNMODIFIEDSINCE

Copies the object if it hasn’t been modified since the specified time.

--API-CopySourceRange=COPYSOURCERANGE

The range of bytes to copy from the source object. The range value must use the form bytes=first-last, where the first and last are the zero-based byte offsets to copy. For example, bytes=0-9 indicates that you want to copy the first ten bytes of the source. You can copy a range only if the source object is greater than 5 GB.

--API-CopySourceSSECustomerAlgorithm=COPYSOURCESSECUSTOMERALGORITHM

Specifies the algorithm to use when decrypting the source object (e.g., AES256).

--API-CopySourceSSECustomerKeyMD5=COPYSOURCESSECUSTOMERKEYMD5

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 the encryption key was transmitted without error. Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required

--API-CopySourceSSECustomerKey=COPYSOURCESSECUSTOMERKEY

Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided in this header must be one that was used when the source object was created.

--API-ETag=ETAG

Entity tag returned when the part was uploaded.

--API-Expires=EXPIRES

The date and time at which the object is no longer cacheable.

--API-GrantFullControl=GRANTFULLCONTROL

Gives the grantee READ, READ_ACP, and WRITE_ACP permissions on the object.

--API-GrantReadACP=GRANTREADACP

Allows grantee to read the object ACL.

--API-GrantRead=GRANTREAD

Allows grantee to read the object data and its metadata.

--API-GrantWriteACP=GRANTWRITEACP

Allows grantee to write the ACL for the applicable object.

--API-IfMatch=IFMATCH

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

--API-IfModifiedSince=IFMODIFIEDSINCE

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

--API-IfNoneMatch=IFNONEMATCH

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

--API-IfUnmodifiedSince=IFUNMODIFIEDSINCE

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

--API-Metadata=METADATA

A map (in json string) of metadata to store with the object in S3

--API-MetadataDirective=METADATADIRECTIVE

Specifies whether the metadata is copied from the source object or replaced with metadata provided in the request.

--API-MFA=MFA

The concatenation of the authentication device’s serial number, a space, and the value that is displayed on your authentication device.

--API-RequestPayer=REQUESTPAYER

Confirms that the requester knows that she or he will be charged for the request. Bucket owners need not specify this parameter in their requests. Documentation on downloading objects from requester pays buckets can be found at http://docs.aws.amazon.co m/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.ht ml

--API-ServerSideEncryption=SERVERSIDEENCRYPTION

The Server-side encryption algorithm used when storing this object in S3 (e.g., AES256, aws:kms).

--API-SSECustomerAlgorithm=SSECUSTOMERALGORITHM

Specifies the algorithm to use to when encrypting the object (e.g., AES256).

--API-SSECustomerKeyMD5=SSECUSTOMERKEYMD5

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 the encryption key was transmitted without error. Please note that this parameter is automatically populated if it is not provided. Including this parameter is not required

--API-SSECustomerKey=SSECUSTOMERKEY

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 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.

--API-SSEKMSKeyId=SSEKMSKEYID

Specifies the AWS KMS key ID to use for object encryption. All GET and PUT requests for an object protected by AWS KMS will fail if not made via SSL or using SigV4. Documentation on configuring any of the officially supported AWS SDKs and CLI can be found at http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAW SSDK.html#specify-signature-version

--API-StorageClass=STORAGECLASS
