W3C Listen MANUAL

Command Line Syntax

	listen [ options ]

Options

The order of the options is not important. Currently available options are:-

Getting Help

-v [ a | b | c | g | p | s | t | u ]
Verbose mode: Gives a running commentary on the program's attempts to read data in various ways. As the amount of verbose output is substantial, the -v option can now be followed by zero, one or more of the following flags (without space) in order to differentiate the verbose output generated:
  • a: Anchor relevant information
  • b: Bindings to local file system
  • c: Cache trace
  • g: SGML trace
  • p: Protocol module information
  • s: SGML/HTML relevant information
  • t: Thread trace
  • u: URI relevant information
The -v option without any appended options shows all trace messages. An example is
	-vpt
showing thread and protocol trace messages
-version
Prints out the version number of the software, and the version number of the WWW library, and exits.

Configuration Options

-port <n>
Indicates the port number to listen on. Default is 80
-backlog <n>
