KDUMP 1
NAME
kdump - display kernel trace data
SYNOPSIS
kdump [ -dnlT ] -f trfile ] [ -t trstr ]
DESCRIPTION
Kdump displays kernel trace files produced with ktrace(1) in a human readable format. Without the -f flag, kdump reads the file "ktrace.data" in the current directory. Following is a description of the options:

-d Display all numbers in decimal.

-n Suppress ad hoc translations. Normally kdump tries to decode many system calls into a more human readable format. For example, ioctl values are replaced with the macro name and errno values are replaced with the sys_errlist string. Suppressing this feature yields a more consistent output format and is more amenable to further processing.

-l Loop reading end-of-file.

-T Display timestamps.

-t trstr See -t in ktrace(1).

-f trfile See -t in ktrace(1).

-m maxdata Display at most maxdata bytes when decoding i/o.
