NAME
gcloud storage objects describe - describe a Cloud Storage object
SYNOPSIS
gcloud storage objects describe URL [--additional-headers=HEADER=VALUE] [--fetch-encrypted-object-hashes] [--raw] [--soft-deleted] [--decryption-keys=[DECRYPTION_KEY,…]] [GCLOUD_WIDE_FLAG]
DESCRIPTION
Describe a Cloud Storage object.
EXAMPLES
Describe a Google Cloud Storage object with the url "gs://bucket/my-object":
gcloud storage objects describe gs://bucket/my-object

Describe object with JSON formatting, only returning the "name" key:

gcloud storage objects describe gs://bucket/my-object --format="json(name)"
POSITIONAL ARGUMENTS
URL
Specifies URL of object to describe.
FLAGS
--additional-headers=HEADER=VALUE
Includes arbitrary headers in storage API calls. Accepts a comma separated list of key=value pairs, e.g. header1=value1,header2=value2. Overrides the default storage/additional_headers property value for this command invocation.
--fetch-encrypted-object-hashes
If the initial GET request returns an object encrypted with a customer-supplied encryption key, the hash fields will be null. If the matching decryption key is present on the system, this flag retries the GET request with the key.
--raw
Shows metadata in the format returned by the API instead of standardizing it.
--soft-deleted
Displays soft-deleted resources only. For objects, it will exclude live and noncurrent ones.
ENCRYPTION FLAGS
--decryption-keys=[DECRYPTION_KEY,…]
A comma-separated list of customer-supplied encryption keys (RFC 4648 section 4 base64-encoded AES256 strings) that will be used to decrypt Cloud Storage objects. Data encrypted with a customer-managed encryption key (CMEK) is decrypted automatically, so CMEKs do not need to be listed here.
GCLOUD WIDE FLAGS
These flags are available to all commands: --access-token-file, --account, --billing-project, --configuration, --flags-file, --flatten, --format, --help, --impersonate-service-account, --log-http, --project, --quiet, --trace-token, --user-output-enabled, --verbosity.
