GETCONF(1)                  General Commands Manual                 GETCONF(1)

NAME
     getconf - get configuration values

SYNOPSIS
     getconf system_var
     getconf path_var pathname
     getconf -a [pathname]

DESCRIPTION
     The getconf utility writes the current value of a configurable system
     limit or option variable to the standard output.

     The system_var argument specifies the system variable to be queried.  The
     names of the system variables are from sysconf(3) with the leading "_SC_"
     removed.

     The path_var argument specifies the pathname variable to be queried for
     the specified pathname argument.  The names of the pathname variables are
     from pathconf(2) with the leading "_PC_" removed.

     When invoked with the option -a, getconf writes a list of all applicable
     variables and their values to the standard output, in the format "name =
     value".

     For compatibility with other operating systems, getconf will ignore
     leading underscores in the names specified in the system_var and path_var
     arguments.

EXIT STATUS
     The getconf utility exits 0 on success, and >0 if an error occurs.

EXAMPLES
     To retrieve the number of configured processors, use:

           $ getconf NPROCESSORS_CONF

     To retrieve the maximum number of bytes (excluding the trailing NUL) for
     a filename in the current directory, use:

           $ getconf NAME_MAX .

SEE ALSO
     pathconf(2), confstr(3), limits(3), sysconf(3)

STANDARDS
     The getconf utility conforms to IEEE Std 1003.2-1992 ("POSIX.2").
