module: hostname
author:

    - Hideki Saito (@saito-hideki)
version_added: "1.4"
short_description: Manage hostname
requirements: [ hostname ]
description:
    - Set system's hostname. Supports most OSs/Distributions including those using C(systemd).
    - Windows, HP-UX, and AIX are not currently supported.
notes:
    - This module does B(NOT) modify C(/etc/hosts). You need to modify it yourself using other modules such as M(ansible.builtin.template)
      or M(ansible.builtin.replace).
    - On macOS, this module uses C(scutil) to set C(HostName), C(ComputerName), and C(LocalHostName). Since C(LocalHostName)
      cannot contain spaces or most special characters, this module will replace characters when setting C(LocalHostName).
options:
    name:
        description:
            - Name of the host.
            - If the value is a fully qualified domain name that does not resolve from the given host,
              this will cause the module to hang for a few seconds while waiting for the name resolution attempt to timeout.
