36.Op Fl v
37.Op Fl q
38.Ar
39.Sh DESCRIPTION
40The
41.Nm
42utility loads
43.Ar file Ns Pa .ko
44into the kernel using the kernel linker.
45Note that if multiple modules are specified then an attempt will
46be made to load them all, even if some fail.
47The
48.Pa .ko
49extension name is not mandatory when loading a given module
50using
51.Nm .
52It does not hurt to specify it though.
53.Pp
54If a bare filename is requested it will only be loaded if it is found within
55the module path as defined by the sysctl
56.Va kern.module_path .
57To load a module from the current directory it must be specified as a full or
58relative path.
59The
60.Nm
61utility will warn if a module is requested as a bare filename and is present
62in the current directory.
63.Pp
64The following options are available:
65.Bl -tag -width indent
66.It Fl v
67Be more verbose.
68.It Fl q
69Silence any extraneous warnings.
70.El
71.Sh NOTES
72.Pp
73The kernel security level settings may prevent a module from being
74loaded or unloaded by giving
75.Em "Operation not permitted" .
76.Sh FILES
77.Bl -tag -width /boot/kernel -compact
78.It Pa /boot/kernel
79directory containing loadable modules.
80Modules must have an extension of
81.Pa .ko .
82.El
83.Sh EXIT STATUS
84.Ex -std
85.Sh EXAMPLES
86To load by module name:
87.Bd -literal -offset indent
88\*[Gt] kldload foo
89.Ed
90.Pp
91To load by file name within the module path:
92.Bd -literal -offset indent
93\*[Gt] kldload foo.ko
94.Ed
95.Pp
96To load by relative path:
97.Bd -literal -offset indent
98\*[Gt] kldload ./foo.ko
99.Ed
100.Pp
101To load by full path:
102.Bd -literal -offset indent
103\*[Gt] kldload /boot/kernel/foo.ko
104.Ed
105.Sh AUTOMATICALLY LOADING MODULES
106Some modules (pf, ipfw, ipf, etc.) may be automatically loaded at boot
107time when the corresponding
108.Xr rc.conf 5
109statement is used.
110Modules may also be auto-loaded through their addition to
111.Xr loader.conf 5 .
