GETCONF(1)                                                          GETCONF(1)



NAME
     getconf - get configuration variables (XPG4)

SYNOPSIS
     getconf system_var

     getconf path_var path_name

DESCRIPTION
     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
     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
     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):

     pathname

               A pathname for which the variable specified by path_var is to
               be determined.

     system_var

               A name of a configuration variable whose value is available
               from the sysconf() function.  All of the values in the
