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

Command Syntax

./coscli cp <source_path> <destination_path> [flags]

Note：

• For more information on bucketAlias, see Download and Installation Configuration.
• For other common options of this command (such as switching bucket and user account), see Common Options.

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 for the object to upload. Default value: STANDARD
None	--part-size	Part size. Default value: 32 MB
None	--thread-num	Number of concurrent threads. Default value: 5
None	--rate-limiting	Speed limit for a single URL. Value range: 0.1-100 MB/s

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 files that meet specific criteria.
• When using zsh, you may need to add double quotes at both ends of the pattern string.

./coscli cp ~/test/ cos://bucket1/example/ -r --include ".*.mp4"

Examples

Upload

./coscli cp ~/test/ cos://bucket1/example/ -r --include .*.mp4

Uploading all non-MD objects in the local directory test to the example directory in the bucket1 bucket

./coscli cp ~/test/ cos://bucket1/example/ -r --exclude .*.md

Uploading all objects in the dir directory (containing the dirA, dirB, dirC, and dirD subdirectories) except the dirD directory

./coscli cp dir/ cos://bucket1/example/ -r --exclude dirD/.*

Uploading all objects in the local directory test to the example directory in the bucket1 bucket using the ARCHIVE storage class
