config

PURPOSE

     Extracts  configuration  information  from  configuration
     files.

SYNOPSIS
     config [ [ -m mfile ] [ -c cfile ] [ -l spfile ] systemfile ]

DESCRIPTION

     The config program  reads the AIX master  and system con-
     figuration files  (by default /etc/master and  the speci-
     fied systemfile).   It writes a C  Language configuration
     file and a special file  list (by default conf.c and spe-
     cials).  The  special file list  is a list of  the mknod,
     chown, and chmod  commands that the shell  runs to define
     the  necessary special  files.   The return  code is  the
     number of errors encountered.

     The C  Language configuration  file can then  be compiled
     and linked  with other kernel  object files to  produce a
     new kernel.   Normally, when you want  to reconfigure the
     kernel, you should run the make command with the Makefile
     supplied in the /usr/sys directory.  This runs config and
     then builds a new kernel.   For a discussion of reconfig-
     uring the kernel, see Managing the AIX Operating System.

FLAGS

     -c  cfile   Writes  the  C  configuration file  to  cfile
                 instead of to conf.c.
     -l  spfile  Writes  the  special  file list  commands  to
                 spfile instead of to specials.
     -m  mfile   Reads mfile instead of /etc/master.

FILES

     /etc/master    Default master configuration file.
     /etc/system    A system configuration file.
     conf.c         Default C configuration file.
     specials       Default special file list.
