|
|
.Op Ar path ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
command is used to generate hint files which list modules, their
|
|
version numbers, and the files that contain them.
|
|
These hints are used by the kernel loader to determine where to find a
|
|
particular KLD module.
|
|
.Pp
|
|
A separate hint file is generated for each directory listed on the
|
|
command line that contains modules.
|
|
If no hint records are generated for a particular directory, no hint
|
|
file is created, and the preexisting hint file (if there was one in
|
|
that directory) is removed.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width ".Fl f Ar file"
|
|
.It Fl R
|
|
Recurse into subdirectories.
|
|
.It Fl d
|
|
Do not generate a hint file, but print module metadata on standard
|
|
output.
|
|
.It Fl f Ar file
|
|
Specify a different name for the hint files than
|
|
.Pa linker.hints .
|
|
.It Fl v
|
|
Operate in verbose mode.
