.Sh DESCRIPTION
|
|
.Nm
|
|
displays the kernel trace files produced with
|
|
.Xr ktrace 1
|
|
in human readable format.
|
|
The file
|
|
.Pa ktrace.out
|
|
in the current directory is displayed, unless either the
|
|
.Fl f
|
|
option is used, or a file name is supplied as the last argument.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Fl
|
|
.It Fl d
|
|
Display all numbers in decimal.
|
|
.It Fl e Ar emulation
|
|
If an emulation of a process is unknown,
|
|
interpret system call maps assuming the named emulation instead of
|
|
default "netbsd".
|
|
.It Fl f Ar file
|
|
Display the specified file instead of
|
|
.Pa ktrace.out .
|
|
.It Fl l
|
|
Loop reading the trace file, once the end-of-file is reached, waiting for
|
|
more data.
|
|
.It Fl m Ar maxdata
|
|
Display at most
|
|
.Ar maxdata
|
|
bytes when decoding
|
|
.Tn I/O .
|
|
.It Fl p Ar pid
|
|
Only display records from the trace file that are for the indicated pid.
|
|
.It Fl n
|
|
Suppress ad hoc translations.
|
|
Normally
|
|
.Nm
|
|
tries to decode many system calls into a more human readable format.
|
|
For example,
|
|
.Xr ioctl 2
|
|
values are replaced with the macro name and
|
|
.Va errno
|
|
values are replaced with the
|
|
.Xr strerror 3
|
|
string.
|
|
Suppressing this feature yields a more consistent output format and is
|
|
easily amenable to further processing.
|
|
.It Fl R
|
|
Display relative timestamps (time since previous entry).
|
|
.It Fl T
|
|
Display absolute timestamps for each entry (seconds since epoch).
|
|
.It Fl t Ar trstr
|
|
See the
|
|
.Fl t
|
|
option of
|
|
.Xr ktrace 1 .
