NAME    [Toc]    [Back]

     getconf - get configuration variables (XPG4)

SYNOPSIS    [Toc]    [Back]

     getconf system_var

     getconf path_var path_name

DESCRIPTION    [Toc]    [Back]

     getconf provides a	method to determine the	current	values of certain
     configurable system limits, options and parameters.

     If	the system_var argument	is given, getconf(1) will print	the value of
     each requested system parameter, one per line.

     If	the path_var and pathname arguments are	given, getconf(1) will print
     the value of the requested	variable specified by the path_var argument
     for the path specified by the pathname operand.

STDOUT    [Toc]    [Back]

     If	the specified variable is defined on the system	and its	value is
     described to be available,	its value will be written in the following
     format:

	  "%s\n", <value>

     Otherwise,	if the specified variable is defined on	the system, its	value
     will be written in	the following format:

	  "%d\n", <value>

     If	the specified variable is valid, but is	undefined on the system,
     getconf will write	using the following format:

	  "undefined\n"

     If	the variable name is invalid or	an error occurs, nothing will be
     written to	standard output.

OPERANDS    [Toc]    [Back]

     The following operands are	supported:

     path_var

	       A name of a configuration variable whose	value is available
	       from the	pathconf() function.  All of the values	in the
	       following table are supported in	addition to others described
	       in pathconf(1):
