KDUMP(1) BSD General Commands Manual KDUMP(1)

NAME
     kkdduummpp - display kernel trace data

SYNOPSIS
     kkdduummpp [-ddnnllRRTT] [-ff file] [-mm maxdata] [-tt [cnisuw]]

DESCRIPTION
     The kkdduummpp command displays the kernel trace files produced with ktrace(1)
     in human readable format.  By default, the file ktrace.out in the current
     directory is displayed.

     The options are as follows:

     -dd          Display all numbers in decimal.

     -ff file     Display the specified file instead of ktrace.out.

     -ll          Loop reading the trace file, once the end-of-file is reached,
                 waiting for more data.

     -mm maxdata  Display at most maxdata bytes when decoding I/O.

     -nn          Suppress ad hoc translations.  Normally kkdduummpp tries to decode
                 many system calls into a more human readable format.  For
                 example, ioctl(2) values are replaced with the macro name and
                 errno values are replaced with the strerror(3) string.  Sup-
                 pressing this feature yields a more consistent output format
                 and is easily amenable to further processing.

     -RR          Display relative timestamps (time since previous entry).

     -TT          Display absolute timestamps for each entry (seconds since
                 epoch).

     -tt cnisuw   See the -tt option of ktrace(1).
