Windows Service equivalent in Linux?

A Windows service is the equivalent of a UNIX daemon. It is a process that provides one or more facilities to client processes.

Starting and Stopping Services

sudo systemctl list-units --type=service --state running                || List all running services
sudo systemctl start <service_name>                      || Starts a service.
sudo systemctl stop <service_name>                       || Stops a service.
sudo systemctl restart <service_name>                    || Restarts a service.
sudo systemctl enable <service_name>                     || Configures a service to start automatically at boot.
sudo systemctl disable <service_name>                    || Prevents a service from starting automatically at boot.
sudo systemctl status <service_name>                     || Shows the current status of a service.
