Terakhir diperbarui: 2025-05-09 18:27:39

The du command is used to list the statistical information of files per storage type under a bucket or a folder. The statistical information includes the total files of different storage types and the total size of the file per type.
Note: 
If you need to use this command to stat information of all objects, when you perform authorization policy, set action to cos:HeadBucket, cos:GetBucket. 
If you need to use this command to stat all historical version information, when you perform authorization policy, set action to cos:HeadBucket, cos:GetBucketVersioning, cos:GetBucketObjectVersions. 
For more authorizations, please refer to CAM-Enabled API.
Command Syntax
./coscli du cos://<bucket-name>[/prefix/] [flag]
du includes the following parameters:
Parameter Format
Description
Example
cos://<bucket-name>
Specifies the target bucket, which 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.
Access with the bucket alias: cos://example-alias
Access with the bucket name: cos://examplebucket-1250000000
/prefix/
Specifies a directory (optional).
/picture/
du includes the following optional flags:
Flag Abbreviation
Flag Name
Description
-h
--help
Views the usage of this command.
None
--include
Includes specific objects.
None
--exclude
Excludes specific objects.
None
--all-versions 
All version data of the statistical object is only available after version control is enabled for the bucket. The statistical information will include the count of DeleteMarkers.
Note: 
--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 enclose the pattern string with double quotation marks.
./coscli du cos://bucket1/picture/ --include ".*\\.mp4$"
For more general options for this command (such as switching buckets or user accounts), see Common Options.
Examples
Listing statistics on objects in the bucket1 bucket
./coscli du cos://bucket1
The returned information includes the number and size of objects in different storage classes, total number of objects, and total object size in the bucket. Below is an example:
       STORAGE CLASS      | OBJECTS COUNT | TOTAL SIZE
