System V Service

There are many command line tools you can use to manage Sys V services.

List services

$ service --status-all

Start a service

$ sudo service networking start

Stop a service

$ sudo service networking stop

Restart a service

$ sudo service networking restart

These commands aren't specific to Sys V init systems, you can use these commands to manage Upstart services as well. Since Linux is trying to move away from the more traditional Sys V init scripts, there are still things in place to help that transition.

Exercise

Manage a couple of services and change their states, what do you observe?
