KDUMP(1)                     BSD Reference Manual                     KDUMP(1)

NAME
     kdump - display kernel trace data

SYNOPSIS
     kdump [-dnlRT] [-f file] [-m maxdata] [-t [cnis]]

DESCRIPTION
     Kdump displays the kernel trace files produced with ktrace(1) in human
     readable format.  By default, the file ktrace.out in the current directo-
     ry is displayed.

     The options are as follows:

     -d          Display all numbers in decimal.

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

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

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

     -n          Suppress ad hoc translations.  Normally kdump tries to decode
                 many system calls into a more human readable format.  For ex-
                 ample, 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.

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

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

     -t cnis     See the -t option of ktrace(1).
