Thanks. But why do some commands require service service-name command (like sshd) where postfix works without the service command in front of it?
'service command option' is essentially the same as: /etc/rc.d/init.d/command option so it runs the standard startup/shutdown script.
'command option' is going to run the first instance of 'command' it finds in your execution search $PATH, and then it is up to that command to interpret the option. In other words there is no way to generalize about this case.
