LIST COMMAND FLAGS: --filter=EXPRESSION

Apply a Boolean filter EXPRESSION to each resource item to be listed. If the expression evaluates True, then that item is listed. For more details and examples of filter expressions, run $ gcloud topic filters. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--limit=LIMIT

Maximum number of resources to list. The default is unlimited. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.

--page-size=PAGE_SIZE

Some services group resource list output into pages. This flag specifies the maximum number of resources per page. The default is determined by the service if it supports paging, otherwise it is unlimited (no paging). Paging may be applied before or after --filter and --limit depending on the service.

--sort-by=[FIELD,…]

Comma-separated list of resource field key names to sort by. The default order is ascending. Prefix a field with ``~´´ for descending order on that field. This flag interacts with other flags that are applied in this order: --flatten, --sort-by, --filter, --limit.
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.
