How to get a list of all services?

Question

linux

Hi everyone
There are two commands in ubuntu:

initctl list
service --status-all

However, getting normal service statuses for processing in scripts is difficult:

started/not started,
autoload enabled/not enabled

While parsing all the services, then individually initctl status ssh/service ssh status — which is not pretty =(

#!/bin/bash
