gcloud alpha storage tail - outputs the last parts (the tail) of an object to stdout

gcloud alpha storage tail URL [--additional-headers=HEADER=VALUE] [--bytes=BYTES; default="1000"] [--follow] [--decryption-keys=[DECRYPTION_KEY,…]] [GCLOUD_WIDE_FLAG …]

gcloud alpha storage tail gs://my-bucket/object

The following command outputs the last 100 bytes of an object:

gcloud alpha storage tail gs://my-bucket/object --bytes=100

The following command continuously streams new data as it is appended to the appendable object:

gcloud alpha storage tail gs://my-bucket/appendable-object --follow

URL

The URL of the object to tail.

--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.

--bytes=BYTES; default="1000"

Output the last BYTES bytes of the object, or use +BYTES to output starting with byte BYTES of the object (capped at object size). Default is 1000.

--follow

Output the last B bytes of the appendable object and continuously streams new bytes appended to the appendable object.

--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.
