The result should be tested when you care about it.

Probably not. In fact, sometimes that is desired -- the stop command
will often exit with an error status if the daemon wasn't already
running, and in this case you want to start it again anyways.

You look for the situation where an error in an earlier command means
that you shouldn't execute the second command. It all depends on what
the commands are and what the errors mean and what you want to do
about them.
