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
               unsigned 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
