How to find out what linux starts at startup?

Question

linux

There is a system in which some program is launched, I need to find out where it lies and what else is launched with it.
There is nothing similar in standard console output, mostly standard services.
Maybe you can turn on a more detailed output, where all the sh commands will be registered?
Help me please )

If the distribution kit is on systemd, then you can look into its journal (journalctl -b), and it should hang in the usual top / htop. Further, usually package managers are able to search for a package by an executable file and vice versa, display files belonging to a package, and so on. Further, you can (in the case of systemd) look at the service file of this program - it should indicate what starts with it (for other init systems, there should also be an analogue, depending on the distro).
I did not delve deeply into these issues, but if I had such a problem, I would solve it in a similar way.
