OWFS(5)			     One-Wire File System		       OWFS(5)

       owfs.conf - owfs	programs configuration file

       An OWFS configuration file is specified on the command line:

       owfs -c config_file [other options]
	      The  file	 name  is arbitrary, there is no default configuration
	      file used.

       A configuration file can	be invoked for any of the OWFS programs	( owfs
       (1)  owhttpd (1)	owserver (1) owftpd (1)	) or any of the	language bind-
       ings ( owperl (1) owcapi	(1) owtcl (1) owphp owpython ) to set  command
       line parameters.

       Similar to Unix shell script or perl syntax

	      option # some options (like 'foreground')	take no	values

	      !	server:	opt = value # owserver NOT effected by this line

	      http: opt	= value	# only owhttpd effected	by this	line
	      !	http: opt = value # owhttpd NOT	effected by this line

       owftpd ftp: opt = value # only owftpd effected by this line
	      !	ftp: opt = value # owftpd NOT effected by this line

       owfs   owfs: opt	= value	# only owfs effected by	this line

       1-wire is a wiring protocol and series of devices designed and manufac-
       tured by	Dallas Semiconductor, Inc. The bus is  a  low-power  low-speed
       low-connector scheme where the data line	can also provide power.

       Each  device  is	 uniquely and unalterably numbered during manufacture.
       There are a wide	variety	of devices, including memory, sensors  (humid-
       ity, temperature, voltage, contact, current), switches, timers and data
       loggers.	More complex devices (like thermocouple	sensors) can be	 built
       with  these  basic devices. There are also 1-wire devices that have en-
       cryption	included.

       The 1-wire scheme uses a	single bus master and multiple slaves  on  the
       same  wire.  The	bus master initiates all communication.	The slaves can
       be individually discovered and addressed	using their unique ID.

       Bus masters come	in a variety of	configurations including serial,  par-
       allel, i2c, network or USB adapters.

   OWFS	design
       OWFS  is	 a  suite of programs that designed to make the	1-wire bus and
       its devices easily accessible. The underlying principle is to create  a
       virtual filesystem, with	the unique ID being the	directory, and the in-
       dividual	properties of the device are represented as simple files  that
       can be read and written.

       Details	of  the	 individual slave or master design are hidden behind a
       consistent interface. The goal is to provide an easy set	of tools for a
       software	 designer  to create monitoring	or control applications. There
       are some	performance enhancements in the	implementation,	including data
       caching,	parallel access	to bus masters,	and aggregation	of device com-
       munication. Still the fundamental goal has been ease of use,  flexibil-
       ity and correctness rather than speed.

       owfs.conf  (5)  allows  a  uniform set of command line parameters to be

       Not all OWFS programs use the same command line options,	but  the  non-
       relevant	ones will be ignored.

       Command	line and configuration options can mixed. They will be invoked
       in the order presented. Left to right for the command line. Top to bot-
       tom for the configuration file.

       Configuration files can call other configuration	files. There is	an ar-
       bitrary depth of	5 levels to prevent infinite loops. More than one con-
       figuration file can be specified.
