What command line tool can be used for Google Cloud resource management?

The command line tool used for Google Cloud resource management is gcloud. This tool is the primary interface for interacting with Google Cloud products and services, allowing users to manage resources effectively. It supports a wide range of commands, enabling users to create, configure, and delete resources such as virtual machines, storage buckets, and databases from the command line.

gcloud aids in managing permissions, billing, and project settings, making it essential for administrators and developers working within the Google Cloud environment. It enables automation of resource management tasks, integrates easily with scripts, and is a core component of the Google Cloud SDK.

The other tools mentioned serve different purposes. gsutil is specifically designed for managing Google Cloud Storage resources, while kubectl is used for managing Kubernetes clusters. The option gcloud resources does not represent an actual tool or command within the gcloud suite. Therefore, gcloud is the correct choice as it encompasses a comprehensive set of capabilities for managing Google Cloud resources.
