1. Prepare an S3 bucket, as described in Preparing to Use AWS S3 Bucket for the CLU. 

2. Consider whether you want to download a single data file or multiple data files: 

   • To download a single data file: Plan to specify the path for that data file in the command. 
   • To download multiple data files: In your file system, use a command line editor (such as vi editor) to create a file that lists the paths for all of the DME data files you want to download, delimited by newline. Plan to use the -f option to specify that file in the command. 

3. Run the following command:

   code

   Panel
   borderColor silver borderStyle solid
   Clipboard AllowLineWrap true
   dm_download_dataobject_s3 [optional parameters] [DME data path] <destination S3 bucket> <destination-path> [AWS credentials file path]

   
   

   The following table describes each parameter:

   Parameter	Description
   [-D <REST-response>]	An optional parameter, specifying a path and filename in your file system. The system always creates a response file: If you specify this parameter, the system saves the response from the server to the specified file in the specified location. If you omit this parameter, the system saves the file as download-dataobject-response-header.tmp in your home directory.
   [-o <output-json-file>]	An optional parameter, specifying a path and filename in your file system. The system always creates an output file:  If you specify this parameter, the system saves the output to the specified file in the specified location. If you omit this parameter, the system saves the output as download-dataobject-response-message.json.tmp in your home directory. If the command is successful, the output file is empty.
   [-f <paths-file>] or [DME data path]	One or more paths within DME. Select one of the following methods to specify the data file or data files that you want to download: To specify multiple data files, use the -f parameter to specify a path and filename in your file system, of a file that lists the paths for all of the DME data files you want to download, delimited by newline. To specify a single data file, specify the path for the DME data file you want to download.
   <destination S3 bucket>	The name of the destination S3 bucket.
   <destination path>	The path to and the name of the folder in the destination bucket. Do not begin the path with a slash. If the destination folder structure you specify does not already exist, DME creates it.
   [AWS credentials file path]	The location of the credentials file. If your credentials file is in the default location, as noted in Preparing to Use AWS S3 Bucket for the CLU, you can omit this parameter.

...

The following example uses the credentials file in a non-default location to download a data file from DME. 

In this example, the command performs the following:

...

For another example, consider the following command.

With the following code in the specified file-list.txt file, the above command uses the credentials file in a default location to download multiple data files from various locations in DME.
