      The cp command is used to upload, download, or copy objects.

      Command Syntax

      ./coscli cp <source_path> <destination_path> [flags]
      cp includes the following parameters:
      Parameter Format
      Description
      Example
      source_path
      Source file path, which can be a local path or a COS file path. The COS path is accessible by using the bucket alias or bucket name configured in the configuration file as detailed in Download and Installation Configuration. If you use the bucket name for access, you also need to include the endpoint flag.
      Local path: ~/example.txt
      COS file path specified with the bucket alias: cos://bucketalias/example.txt
      COS file path specified with the bucket name: cos://examplebucket-1250000000/example.txt
      destination_path
      Destination file path, which can be a local path or a COS file path. The COS path is accessible by using the bucket alias or bucket name configured in the configuration file as detailed in Download and Installation Configuration. If you use the bucket name for access, you also need to include the endpoint flag.
      Local path: ~/example.txt
      COS file path specified with the bucket alias: cos://bucketalias/example.txt
      COS file path specified with the bucket name: cos://examplebucket-1250000000/example.txt
      cp includes the following optional flags:
      Flag Abbreviation
      Flag Name
      Description
      None
      --include
      Includes specific objects.
      None
      --exclude
      Excludes specific objects.
      -r
      --recursive
      Specifies whether to traverse all objects in the directory recursively.
      None
      --storage-class
      Specifies the storage class of the uploaded file. Default value: STANDARD. For more information, see Storage Class Overview.
      None
      --part-size
      Part size in MB. Default value: 32 MB
      None
      --thread-num
      Number of concurrent threads. Default value: 5
      None
      --rate-limiting
      Speed limit for a single URL in MB/s. Value range: 0.1–100 MB/s
      None
      --meta
      Metadata of the uploaded file, including certain HTTP standard attributes (HTTP Header) and custom metadata prefixed with x-cos-meta- (User Meta). The file metadata is in the format of header:value#header:value, such as Expires:2022-10-12T00:00:00.000Z#Cache-Control:no-cache#Content-Encoding:gzip#x-cos-meta-x:x.
      Note:
      cp automatically uses concurrent upload/download for large objects.
      If an object is larger than --part-size, COSCLI will split the object into multiple parts according to --part-size and use --thread-num threads to concurrently upload/download the object.
      Each thread maintains a URL. For each URL, you can use the --rate-limiting parameter to limit the speed of a single URL. When concurrent upload/download is enabled, the total rate is --thread-num * --rate-limiting.
      If an object is uploaded/downloaded in parts, checkpoint restart will be enabled by default.
      --include and --exclude support standard regular expression syntax, so you can use them to filter out objects that meet specific criteria.
      When using zsh, you may need to add double quotes at both ends of the pattern string.``plaintext ./coscli cp ~/test/ cos://bucket1/example/ -r --include ".*.txt" --meta=x-cos-meta-a:a#ContentType:text#Expires:2022-10-12T00:00:00.000Z``> - For other common options of this command (such as switching bucket and user account), see Common Options.
