kldconfig

KLDCONFIG(8)						    BSD System Manager's Manual 					      KLDCONFIG(8)

NAME

     kldconfig -- display or modify the kernel module search path

SYNOPSIS

     kldconfig [-dfimnUv] [-S sysctlname] [path ...]
     kldconfig -r

DESCRIPTION

     The kldconfig utility displays or modifies the search path used by the kernel when loading modules using the kldload(8) utility or the
     kldload(2) syscall.

     The following options are available:

     -d      Remove the specified paths from the module search path.

     -f      Do not display a diagnostic message if a path specified for adding is already present in the search path, or if a path specified for
	     removing is not present in the search path.  This may be useful in startup/shutdown scripts for adding a path to a file system which
	     is still not mounted, or in shutdown scripts for unconditionally removing a path that may have been added during startup.

     -i      Add the specified paths to the beginning of the search path, not to the end.  This option can only be used when adding paths.

     -m      Instead of replacing the module search path with the set of paths specified, ``merge'' in the new entries.

     -n      Do not actually change the module search path.

     -r      Display the current search path.  This option cannot be used if any paths are also specified.

     -S sysctlname
	     Specify the sysctl name to use instead of the default kern.module_path.

     -U      ``Unique-ify'' the current search path - if any of the directories is repeated one or more times, only the first occurrence remains.
	     This option implies -m.

     -v      Verbose output: display the new module search path.  If the path has been changed, and the -v flag is specified more than once, the
	     old path is displayed as well.

FILES

     /boot/kernel, /boot/modules, /modules
	     The default module search path used by the kernel.

EXIT STATUS

     The kldconfig utility exits 0 on success, and >0 if an error occurs.

SEE ALSO

     kldload(2), kldload(8), sysctl(8)

HISTORY

     The kldconfig utility first appeared in FreeBSD 4.4.
