|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl aksx
|
|
.Op Ar modules-path Op Ar outfile
|
|
.Sh DESCRIPTION
|
|
By default,
|
|
.Nm
|
|
reads
|
|
.Xr kldstat 8
|
|
output from standard input and writes to standard output a list of
|
|
.Xr gdb 1
|
|
commands to add symbol files from KLDs in subdirectories of the subdirectory
|
|
.Pa modules
|
|
of the current directory, which is intended to be a kernel build directory.
|
|
This allows
|
|
.Xr gdb 1
|
|
to load the symbols into the debugging environment.
|
|
.Pp
|
|
If
|
|
.Ar modules-path
|
|
is specified,
|
|
.Nm
|
|
uses it for the modules directory instead of the default
|
|
.Pa modules .
|
|
This is useful when building in a non-standard location (i.e., not
|
|
.Pa /usr/src
|
|
and
|
|
.Pa /usr/obj ) .
|
|
.Pp
|
|
If
|
|
.Ar outfile
|
|
is specified,
|
|
.Nm
|
|
writes to it instead of standard output.
|
|
.Sh OPTIONS
|
|
The following options modify the function of
|
|
.Nm :
|
|
.Bl -tag -width indent
|

|
|
When writing to an explicit
|
|
.Ar outfile ,
|
|
append to the file rather than overwriting it.

Instead of reading from standard input, start a
|
|
.Xr kldstat 8
|
|
and read the information from it.

The

|
|
.Ar outfile
|
|
without specifying a module path.
