# head-object

Available in Classic and VPC

Get the metadata of an object stored in a Ncloud Storage bucket.

              Note

              

For a Sub Account user to execute this command, they must have View/GetObject action permissions.

## Syntax

The `head-object` syntax is as follows:

```
aws s3api head-object \
    --bucket <bucket> \
    --key <key> \
    [--version-id <version-id>] \
    [--range <range>] \
    [--part-number <part-number>] \
    [--sse-customer-algorithm <sse-customer-algorithm>] \
    [--sse-customer-key <sse-customer-key>] \
    [--sse-customer-key-md5 <sse-customer-key-md5>] \
    --endpoint-url <endpoint-url>
```

              Note

              

When you query an object for which object lock retention or legal hold has been set, the `ObjectLockMode`, `ObjectLockRetainUntilDate`, and `ObjectLockLegalHoldStatus` fields are returned.
