      The ls command is used to query the list of buckets, objects in a bucket, and objects in a directory.

      Command Syntax

      ./coscli ls [cos://<bucket-name>[/prefix/]] [flag]
      ls includes the following parameters:
      Parameter Format
      Description
      Example
      cos://<bucket-name>
      Specifies the optional 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/
      ls includes the following optional flags:
      Flag Abbreviation
      Flag Name
      Description
      -h
      --help

      None
      --include
      Includes specific objects.
      None
      --exclude
      Excludes specific objects.
      -r
      --recursive
      Specifies whether to traverse directories recursively and list all objects.
      None
      --limit
      Specifies the maximum quantity to be listed. (If 0 or no value is configured, the default value is 10000)
      Note:
      --include and --exclude support standard regular expressions. You can use regular expressions to filter objects that meet your requirements.
      When using zsh, you may need to add double quotes at both ends of the pattern string.
      ./coscli ls cos://bucket1 -r --include ".*.mp4"
      For other common options of this command (such as switching buckets and user accounts), see common options.

      Examples

      Listing all buckets of the current account

      ./coscli ls
      The returned information includes the bucket name, region, creation time, and total number of buckets. Below is an example:
                 BUCKET NAME          |     REGION      |     CREATE DATE
      --------------------------------+-----------------+-----------------------
        examplebucket-1250000000      | ap-nanjing      | 2022-01-01T00:00:00Z
      --------------------------------+-----------------+-----------------------
                                        TOTAL BUCKETS:  |          1
                                      ------------------+-----------------------

      Listing objects

      Listing all objects in the bucket1 bucket

      ./coscli ls cos://bucket1
      The returned information includes the object key (the unique identifier of the object in the bucket), storage class, last update time, object size, and total number of objects. Below is an example:
              KEY      |   TYPE   |      LAST MODIFIED       |  SIZE
      -----------------+----------+--------------------------+---------
              test.txt | STANDARD | 2022-01-01T00:00:00.000Z |   2  B
      -----------------+----------+--------------------------+---------
                                         TOTAL OBJECTS:      |   1
                                  ---------------------------+---------

      Listing all objects and subdirectories in the picture directory in the bucket1 bucket

      ./coscli ls cos://bucket1/picture/
      General listing only returns the data at the level of the query path, without expanding subpaths. Below is an example:
              KEY        |   TYPE   |      LAST MODIFIED       |  SIZE
      -------------------+----------+--------------------------+---------
       picture/subfolder |      DIR |                          |   
        picture/pic1.png | STANDARD | 2022-01-01T00:00:00.000Z | 162  B
      -------------------+----------+--------------------------+---------
                                         TOTAL OBJECTS:        |   2
                                  -----------------------------+---------

      Listing all objects in the picture directory in the bucket1 bucket recursively

      ./coscli ls cos://bucket1/picture/ -r
      If there are subpaths at the level of the query path, recursive listing will scan all subpaths and return all files under the level of the query path. Below is an example:
                   KEY            |   TYPE   |      LAST MODIFIED       |  SIZE
      ----------------------------+----------+--------------------------+---------
       picture/subfolder/pic2.png |      DIR |                          |   
                picture/subfolder |      DIR |                          |   
                 picture/pic1.png | STANDARD | 2022-01-01T00:00:00.000Z | 162  B
      ----------------------------+----------+--------------------------+---------
                                                  TOTAL OBJECTS:        |   2
                                           -----------------------------+---------

      Listing all MP4 objects in the bucket1 bucket recursively

      ./coscli ls cos://bucket1 -r --include .*.mp4

      Listing all non-MP4 objects in the bucket1 bucket recursively

      ./coscli ls cos://bucket1 -r --exclude .*.mp4

      Listing all non-JPG objects prefixed with test in the picture directory in the bucket1 bucket

      ./coscli ls cos://bucket1/picture -r --include ^picture/test.* --exclude .*.jpg
