34.Nd generate hints for the kernel loader
35.Sh SYNOPSIS
36.Nm
37.Op Fl Rdv
38.Op Fl f Ar hintsfile
39.Ar path ...
40.Sh DESCRIPTION
41The
42.Nm
43utility is used to generate hint files which list modules, their
44version numbers, and the files that contain them.
45These hints are used by the kernel loader to determine where to find a
46particular KLD module.
47.Pp
48A separate hint file is generated for each directory listed on the
49command line that contains modules.
50If no hint records are generated for a particular directory, no hint
51file is created, and the preexisting hint file (if there was one in
52that directory) is removed.
53.Pp
54The following options are available:
55.Bl -tag -width indent
56.It Fl R
57Recurse into subdirectories.
58.It Fl d
59Do not generate a hint file, but print module metadata on standard
60output.
61.It Fl f Ar hintsfile
62Specify a different name for the hints files than
63.Pa linker.hints .
64.It Fl v
65Operate in verbose mode.
66.El
67.Sh EXAMPLES
68To build hint files for both standard and add-on modules:
69.Pp
70.Dl "kldxref /boot/kernel /boot/modules"
71.Pp
72To build hint files for all installed kernels:
73.Pp
74.Dl "kldxref -R /boot"
