Disabled units

[ratatosk85]

Hello, thanks for the script, but there is a problem:
if the unit is disabled, then it is not displayed in the systemctl list-units list. I modified a little for myself - added one more loop before the main one:

lines = subprocess.check_output(["/bin/systemctl", "list-units", "-a", "-t", "service", "--no-legend"]).decode("UTF-8").split("\n")
lines_disabled = subprocess.check_output(["/bin/systemctl", "list-unit-files", "-a", "-t", "service", "--no-legend"]).decode("UTF-8").split("\n")
        for line in lines_disabled:
            if line and not "@." in line:
               result = re.search(r"^(.+)\.service\s+(\w+).*$", line)
               service_name = result.group(1)
               service_mode = result.group(2)
               if service_mode == 'disabled':
                    service_mode = 3
                    service_oid = self.create_oid(service_name)
                    self.data[service_oid] = ('integer', service_mode, service_name)
                    oids.append(service_oid)

        for line in lines:
            if line and not "@." in line:
            ...

I think a good programmer will make it more beautiful
