Getting information about an object

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

1. See the description of the CLI command for getting information about an object:

   yc storage s3api head-object --help
   

2. Get a list of buckets in the default folder:

   yc storage bucket list
   

   Result:

   +------------------+----------------------+-------------+-----------------------+---------------------+
   |       NAME       |      FOLDER ID       |  MAX SIZE   | DEFAULT STORAGE CLASS |     CREATED AT      |
   +------------------+----------------------+-------------+-----------------------+---------------------+
   | first-bucket     | b1gmit33ngp6******** | 53687091200 | STANDARD              | 2022-12-16 13:58:18 |
   +------------------+----------------------+-------------+-----------------------+---------------------+
   

3. Run this command:

   yc storage s3api head-object \
     --bucket <bucket_name> \
     --key <object_key>
   

   Where:

   • --bucket: Name of your bucket.
   • --key: Object key.

   Result:

   etag: '"d41d8cd98f00b204e9800998********"'
   request_id: 6428ce25********
