        required: True
    notes:
      - Like all lookups this runs on the Ansible controller and is unaffected by other keywords, such as become,
        so if you need to different permissions you must change the command or run Ansible as another user.
      - Alternatively you can use a shell/command task that runs against localhost and registers the result.
      - Pipe lookup internally invokes Popen with shell=True (this is required and intentional).
        This type of invocation is considered a security issue if appropriate care is not taken to sanitize any user provided or variable input.
        It is strongly recommended to pass user input or variable input via quote filter before using with pipe lookup.
        See example section for this.

            shell as the program to execute. If shell is True, it is recommended to pass
