Script to scan host doesn't work

[diocanelebbrosobastardo]

hi I'm using openvas that I installed on kali linux (installed on virtual box) ...

what i would like to do is scan my system .... i found this script, only once i give it the command to run it, which is suggested by the script itself, i get this:

usage: gvm-script [-h] [-c [CONFIG]] [--log [{DEBUG, INFO, WARNING, ERROR, CRITICAL}]] [--timeout TIMEOUT] [--gmp-username GMP_USERNAME]
                  [--gmp-password GMP_PASSWORD] [-V] [--protocol {GMP, OSP}]
                  CONNECTION_TYPE ...
gvm-script: error: the following arguments are required: CONNECTION_TYPE
unknown option - -
usage: ssh [-46AaCfGgKkMNnqsTtVvXxYy] [-B bind_interface]
           [-b bind_address] [-c cipher_spec] [-D [bind_address:] port]
           [-E log_file] [-e escape_char] [-F configfile] [-I pkcs11]
           [-i identity_file] [-J [user @] host [: port]] [-L address]
           [-l login_name] [-m mac_spec] [-O ctl_cmd] [-o option] [-p port]
           [-Q query_option] [-R address] [-S ctl_path] [-W host: port]
           [-w local_tun [: remote_tun]] destination [command [argument ...]]

this is the script I used, found in the openVAS github page:

https://github.com/greenbone/gvm-tools/blob/main/scripts/scan-new-system.gmp.py

from gvm.protocols.gmp import Gmp


def check_args(args):
    len_args = len(args.script) - 1
    message = """
        This script starts a new scan on the given host.
        It needs one parameters after the script name.
        1. <host_ip>        IP Address of the host system
        2. <port_list_id>   Port List UUID for scanning the host system.

2 problems are also reported: "gmp" is not defined, ln87 "args" is not defined, ln87

can anyone please help me ?

You need to run a GMP script via gvm-script [connection type] /path/to/script.gmp.py.
