We have done our best to make Passenger user-friendly, but it is still possible for users to get stuck or to need help. So before we conclude this tutorial, we will teach you how to get help.

The --help option

Although this Library is a good source of information on using Passenger, you do not have to consult this Library for everything. Passenger is self-documenting: every Passenger command supports the --help option, which will provide you with basic information about the command, its behavior and its syntax.

Here is an example of passenger --help:

$ passenger --help
Phusion Passenger Standalone, the easiest way to run web apps.

Available commands:

  passenger start      Start Phusion Passenger Standalone.
  passenger stop       Stop a Phusion Passenger instance.
  passenger status     Show the status of a running Phusion Passenger instance.

Run 'passenger <COMMAND> --help' for more information about each command.

Many Passenger commands support subcommands. These subcommands, too, support --help. The above output already suggested that you can run passenger start --help:

$ passenger start --help
Usage: passenger start [DIRECTORY] [OPTIONS]
Starts Passenger Standalone and serve one or more web applications.

Server options:
    -a, --address HOST               Bind to the given address.
    -p, --port NUMBER                Use the given port number. Default: 3000

So if you want to know what a command does and whether its behavior can be modified, please do not hestitate to pass --help.
