Parameter Description

Parameter	Optional or Mandatory	Description
bucket	Mandatory	Bucket name
prefix	Optional	Prefix of an object name for listing objects NOTE: If this parameter is left blank, all objects in the bucket are listed.
s	Optional (additional parameter)	Displays simplified query result. NOTE: In the simplified format, the returned result contains only the object name.
d	Optional (additional parameter)	Lists only objects and subdirectories in the current directory, instead of recursively listing all objects and subdirectories. NOTE: According to the naming conventions in OBS, a slash (/) is used as the directory separator.
v	Optional (additional parameter)	Lists versions of an object in a bucket. The result contains the latest version and historical versions (if any) of the object.
marker	Optional (additional parameter)	Object name to start with when listing objects in a bucket. All objects are listed in lexicographical order by object name. NOTE: For details about how to use this parameter, see Listing.
versionIdMarker	Optional (additional parameter). It must be used together with the v and marker parameters.	Version ID to start with when listing versions of objects in a bucket. All versions and objects are listed in lexicographical order by object name and version ID. NOTE: If the value of versionIdMarker is not a version ID specified by marker, versionIdMarker is invalid.
bf	Optional (additional parameter)	Display formats of bytes in the listing result. Possible values are: human-readable raw NOTE: If this parameter is not configured, the display format of bytes in the result is determined by the humanReadableFormat parameter in the configuration file.
du	Optional (additional parameter)	Quickly returns the total size of listed objects, without displaying detailed object information. This parameter can be used together with other parameters. NOTE: If there are too many objects listed, wait for a while.
limit	Optional (additional parameter)	Maximum number of objects that can be listed. If the value is less than or equal to 0, all objects are listed. If it is left blank, 1000 objects are listed by default. NOTE: If there are a large number of objects in a bucket, you are advised to set this parameter to limit the number of objects to be listed each time. If not all objects are listed, marker and versionIdMarker of the next request will be returned in the result, which you can use to list the remaining objects.
format	Optional (additional parameter)	Prints a listing result in the user-defined format. Currently, the value can only be default, indicating that the listing result is displayed in one row.
config	Optional (additional parameter)	User-defined configuration file for executing a command. For details about parameters that can be configured, see Parameter Description.
