Options
paths (string)
--dryrun (boolean) Displays the operations that would be performed using the specified command without actually running them.
--quiet (boolean) Does not display the operations performed from the specified command.
--include (string) Don't exclude files or objects in the command that match the specified pattern. See Use of Exclude and Include Filters for details.
--exclude (string) Exclude all files or objects from the command that matches the specified pattern.
--acl (string) Sets the ACL for the object when the command is performed. If you use this parameter you must have the "s3:PutObjectAcl" permission included in the list of actions for your IAM policy. Only accepts values of private, public-read, public-read-write, authenticated-read, aws-exec-read, bucket-owner-read, bucket-owner-full-control and log-delivery-write. See Canned ACL for details
--follow-symlinks | --no-follow-symlinks (boolean) Symbolic links are followed only when uploading to S3 from the local filesystem. Note that S3 does not support symbolic links, so the contents of the link target are uploaded under the name of the link. When neither --follow-symlinks nor --no-follow-symlinks is specified, the default is to follow symlinks.
--no-guess-mime-type (boolean) Do not try to guess the mime type for uploaded files. By default the mime type of a file is guessed when it is uploaded.
--sse (string) Specifies server-side encryption of the object in S3. Valid values are AES256 and aws:kms. If the parameter is specified but no value is provided, AES256 is used.
--sse-c (string) Specifies server-side encryption using customer provided keys of the the object in S3. AES256 is the only valid value. If the parameter is specified but no value is provided, AES256 is used. If you provide this value, --sse-c-key must be specified as well.
--sse-c-key (blob) The customer-provided encryption key to use to server-side encrypt the object in S3. If you provide this value, --sse-c must be specified as well. The key provided should not be base64 encoded.
--sse-kms-key-id (string) The customer-managed AWS Key Management Service (KMS) key ID that should be used to server-side encrypt the object in S3. You should only provide this parameter if you are using a customer managed customer master key (CMK) and not the AWS managed KMS CMK.
--sse-c-copy-source (string) This parameter should only be specified when copying an S3 object that was encrypted server-side with a customer-provided key. It specifies the algorithm to use when decrypting the source object. AES256 is the only valid value. If the parameter is specified but no value is provided, AES256 is used. If you provide this value, --sse-c-copy-source-key must be specified as well.
--sse-c-copy-source-key (blob) This parameter should only be specified when copying an S3 object that was encrypted server-side with a customer-provided key. Specifies the customer-provided encryption key for Amazon S3 to use to decrypt the source object. The encryption key provided must be one that was used when the source object was created. If you provide this value, --sse-c-copy-source be specified as well. The key provided should not be base64 encoded.
--storage-class (string) The type of storage to use for the object. Valid choices are: STANDARD | REDUCED_REDUNDANCY | STANDARD_IA | ONEZONE_IA | INTELLIGENT_TIERING | GLACIER | DEEP_ARCHIVE. Defaults to 'STANDARD'
--grants (string)
Grant specific permissions to individual users or groups. You can supply a list of grants of the form
--grants Permission=Grantee_Type=Grantee_ID [Permission=Grantee_Type=Grantee_ID ...]To specify the same permission type for multiple grantees, specify the permission as such as
--grants Permission=Grantee_Type=Grantee_ID,Grantee_Type=Grantee_ID,...Each value contains the following elements:
- Permission - Specifies the granted permissions, and can be set to read, readacl, writeacl, or full.
- Grantee_Type - Specifies how the grantee is to be identified, and can be set to uri or id.
- Grantee_ID - Specifies the grantee based on Grantee_Type. The Grantee_ID value can be one of:
- uri - The group's URI. For more information, see Who Is a Grantee?
- id - The account's canonical ID
For more information on Amazon S3 access control, see Access Control
--website-redirect (string) If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.
--content-type (string) Specify an explicit content type for this operation. This value overrides any guessed mime types.
--cache-control (string) Specifies caching behavior along the request/reply chain.
--content-disposition (string) Specifies presentational information for the object.
--content-encoding (string) 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.
--content-language (string) The language the content is in.
--expires (string) The date and time at which the object is no longer cacheable.
--source-region (string) When transferring objects from an s3 bucket to an s3 bucket, this specifies the region of the source bucket. Note the region specified by --region or through configuration of the CLI refers to the region of the destination bucket. If --source-region is not specified the region of the source will be the same as the region of the destination bucket.
--only-show-errors (boolean) Only errors and warnings are displayed. All other output is suppressed.
--no-progress (boolean) File transfer progress is not displayed. This flag is only applied when the quiet and only-show-errors flags are not provided.
--page-size (integer) The number of results to return in each response to a list operation. The default value is 1000 (the maximum allowed). Using a lower value may help if an operation times out.
--ignore-glacier-warnings (boolean) Turns off glacier warnings. Warnings about an operation that cannot be performed because it involves copying, downloading, or moving a glacier object will no longer be printed to standard error and will no longer cause the return code of the command to be 2.
--force-glacier-transfer (boolean) Forces a transfer request on all Glacier objects in a sync or recursive copy.
--request-payer (string) 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.com/AmazonS3/latest/dev/ObjectsinRequesterPaysBuckets.html
--metadata (map) A map of metadata to store with the objects in S3. This will be applied to every object which is part of this request. In a sync, this means that files which haven't changed won't receive the new metadata. When copying between two s3 locations, the metadata-directive argument will default to 'REPLACE' unless otherwise specified.
Shorthand Syntax:
KeyName1=string,KeyName2=string
JSON Syntax:
{"string": "string"
...}
--metadata-directive (string) Specifies whether the metadata is copied from the source object or replaced with metadata provided when copying S3 objects. Note that if the object is copied over in parts, the source object's metadata will not be copied over, no matter the value for --metadata-directive, and instead the desired metadata values must be specified as parameters on the command line. Valid values are COPY and REPLACE. If this parameter is not specified, COPY will be used by default. If REPLACE is used, the copied object will only have the metadata values that were specified by the CLI command. Note that if you are using any of the following parameters: --content-type, content-language, --content-encoding, --content-disposition, --cache-control, or --expires, you will need to specify --metadata-directive REPLACE for non-multipart copies if you want the copied objects to have the specified metadata values.
--expected-size (string) This argument specifies the expected size of a stream in terms of bytes. Note that this argument is needed only when a stream is being uploaded to s3 and the size is larger than 50GB. Failure to include this argument under these conditions may result in a failed upload due to too many parts in upload.
--recursive (boolean) Command is performed on all files or objects under the specified directory or prefix.
See 'aws help' for descriptions of global parameters.
Examples
Copying a local file to S3
The following cp command copies a single file to a specified bucket and key:
aws s3 cp test.txt s3://mybucket/test2.txt
Output:
upload: test.txt to s3://mybucket/test2.txt
Copying a local file to S3 with an expiration date
The following cp command copies a single file to a specified bucket and key that expires at the specified ISO 8601 timestamp:
aws s3 cp test.txt s3://mybucket/test2.txt --expires 2014-10-01T20:30:00Z
Output:
upload: test.txt to s3://mybucket/test2.txt
Copying a file from S3 to S3
The following cp command copies a single s3 object to a specified bucket and key:
aws s3 cp s3://mybucket/test.txt s3://mybucket/test2.txt
Output:
copy: s3://mybucket/test.txt to s3://mybucket/test2.txt
Copying an S3 object to a local file
The following cp command copies a single object to a specified file locally:
aws s3 cp s3://mybucket/test.txt test2.txt
Output:
download: s3://mybucket/test.txt to test2.txt
Copying an S3 object from one bucket to another
The following cp command copies a single object to a specified bucket while retaining its original name:
aws s3 cp s3://mybucket/test.txt s3://mybucket2/
Output:
copy: s3://mybucket/test.txt to s3://mybucket2/test.txt
Recursively copying S3 objects to a local directory
When passed with the parameter --recursive, the following cp command recursively copies all objects under a specified prefix and bucket to a specified directory. In this example, the bucket mybucket has the objects test1.txt and test2.txt:
aws s3 cp s3://mybucket . --recursive
Output:
download: s3://mybucket/test1.txt to test1.txt download: s3://mybucket/test2.txt to test2.txt
Recursively copying local files to S3
When passed with the parameter --recursive, the following cp command recursively copies all files under a specified directory to a specified bucket and prefix while excluding some files by using an --exclude parameter. In this example, the directory myDir has the files test1.txt and test2.jpg:
aws s3 cp myDir s3://mybucket/ --recursive --exclude "*.jpg"
Output:
upload: myDir/test1.txt to s3://mybucket/test1.txt
Recursively copying S3 objects to another bucket
When passed with the parameter --recursive, the following cp command recursively copies all objects under a specified bucket to another bucket while excluding some objects by using an --exclude parameter. In this example, the bucket mybucket has the objects test1.txt and another/test1.txt:
aws s3 cp s3://mybucket/ s3://mybucket2/ --recursive --exclude "another/*"
Output:
copy: s3://mybucket/test1.txt to s3://mybucket2/test1.txt
You can combine --exclude and --include options to copy only objects that match a pattern, excluding all others:
aws s3 cp s3://mybucket/logs/ s3://mybucket2/logs/ --recursive --exclude "*" --include "*.log"
Output:
copy: s3://mybucket/logs/test/test.log to s3://mybucket2/logs/test/test.log copy: s3://mybucket/logs/test3.log to s3://mybucket2/logs/test3.log
Setting the Access Control List (ACL) while copying an S3 object
The following cp command copies a single object to a specified bucket and key while setting the ACL to public-read-write:
aws s3 cp s3://mybucket/test.txt s3://mybucket/test2.txt --acl public-read-write
Output:
copy: s3://mybucket/test.txt to s3://mybucket/test2.txt
Note that if you're using the --acl option, ensure that any associated IAM policies include the "s3:PutObjectAcl" action:
aws iam get-user-policy --user-name myuser --policy-name mypolicy
Output:
{
"UserName": "myuser",
"PolicyName": "mypolicy",
"PolicyDocument": {
"Version": "2012-10-17",
"Statement": [
{
"Action": [
"s3:PutObject",
"s3:PutObjectAcl"
],
"Resource": [
"arn:aws:s3:::mybucket/*"
],
"Effect": "Allow",
"Sid": "Stmt1234567891234"
}
]
}
}
