SYNOPSIS
gcloud preview compute instances get-screenshot INSTANCE_NAME [--destination=DESTINATION] [--zone=ZONE] [GCLOUD_WIDE_FLAG …]
DESCRIPTION

gcloud preview compute instances get-screenshot test-instance --destination=output.jpg
POSITIONAL ARGUMENTS
INSTANCE_NAME
Name of the instance to get a screenshot from. For details on valid instance names, refer to the criteria documented under the field 'name' at: https://cloud.google.com/compute/docs/reference/rest/v1/instances
FLAGS
--destination=DESTINATION
Filename, including the path, to save the screenshot (JPEG image).
--zone=ZONE
Zone of the instance to get a screenshot from. If not specified, you might be prompted to select a zone (interactive mode only). gcloud attempts to identify the appropriate zone by searching for resources in your currently active project. If the zone cannot be determined, gcloud prompts you for a selection with all available Google Cloud Platform zones.

To avoid prompting when this flag is omitted, the user can set the compute/zone property: 

gcloud config set compute/zone ZONE

A list of zones can be fetched by running: 

gcloud compute zones list

To unset the property, run: 

gcloud config unset compute/zone

Alternatively, the zone can be stored in the environment variable CLOUDSDK_COMPUTE_ZONE.

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.

Run $ gcloud help for details.
