======

The nova client is the command-line interface (CLI) for
the Compute service (nova) API and its extensions.

This chapter documents :command:`nova` version ``9.0.1``.

For help on a specific :command:`nova` command, enter:

.. code-block:: console

   $ nova help COMMAND

.. note:: Over time, command line functionality will be phased out
          of the ``nova`` CLI and into the ``openstack`` CLI. Using
          the ``openstack`` client where possible is preferred but
          there is not full parity yet for all of the ``nova`` commands.
          For information on using the ``openstack`` CLI, see:

          https://docs.openstack.org/python-openstackclient/latest/
