KLDSTAT(8)		FreeBSD	System Manager's Manual		    KLDSTAT(8)

NAME
     kldstat --	display	status of dynamic kernel linker

SYNOPSIS
     kldstat [-h] [-q] [-v] [-d] [-i id] [-n filename]
     kldstat [-q] [-d] [-m modname]

DESCRIPTION
     The kldstat utility displays the status of	any files dynamically linked
     into the kernel.

     The following options are available:

     -h	       Display the size	field in a human-readable form,	using unit
	       suffixes	instead	of hex values.

     -v	       Be more verbose.

     -d	       Show the	module specific	data (as int, unsigned int and un-
	       signed long)

     -i	id     Display the status of only the file with	this ID.

     -n	filename
	       Display the status of only the file with	this filename.

     -q	       Only check if file is loaded or compiled	into the kernel.

     -m	modname
	       Display the status of only the module with this modname.

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

EXAMPLES
     Show files	dynamically linked into	the kernel.  Note the kernel itself is
     shown in the list.	 Refs shows the	number of modules referenced by	each
     file:

	   $ kldstat
	   Id Refs Address		  Size Name
	    1	38 0xffffffff80200000  2448f20 kernel
	    2	 3 0xffffffff82649000	 b7bd8 linux.ko
	    3	 5 0xffffffff82701000	  9698 linux_common.ko
	    4	 1 0xffffffff82b11000	  1eae linsysfs.ko
	    5	 1 0xffffffff82b13000	 f2af8 nvidia-modeset.ko
	    6	 1 0xffffffff82c06000  122b020 nvidia.ko
	    7	 1 0xffffffff83e32000	  2668 intpm.ko
	    8	 1 0xffffffff83e35000	   b50 smbus.ko
	    9	 1 0xffffffff83e36000	  18a0 uhid.ko
	   10	 1 0xffffffff83e38000	  2928 ums.ko
	   11	 1 0xffffffff83e3b000	  1aa0 wmt.ko
	   12	 1 0xffffffff83e3d000	  cd70 snd_uaudio.ko

     Show the verbose status of	the linux file and show	the size in a human
     readable fashion:

	   $ kldstat -h	-v -n linux
	   Id Refs Address	       Size Name
	    2	 3 0xffffffff82649000  735K linux.ko (/boot/kernel/linux.ko)
		   Contains modules:
			    Id Name
			     2 linuxelf

     Same as above using the id	of the file:

	   $ kldstat -h	-i 2 -v
	   Id Refs Address	       Size Name
	    2	 3 0xffffffff82649000  735K linux.ko (/boot/kernel/linux.ko)
		   Contains modules:
			    Id Name
			     2 linuxelf

     Show the status of	the linuxelf module obtained from the example above:

	   $ kldstat -v	-m linuxelf
	   Id  Refs Name
	     2	  1 linuxelf

     Show the module specific data for the g_raid module:

	   $ kldstat -d	-m g_raid
	   Id  Refs Name data..(int, uint, ulong)
	   366	  1 g_raid (0, 0, 0x0)

     Check if the module fakefile is linked.  Returns 0	if it is, 1 otherwise:

	   $ kldstat -q	-n fakefile || echo file not linked
	   file	not linked
