Normally 38.Nm kdump 39tries to decode many 40system calls into a more human readable format. For example, ioctl 41values are replaced with the macro name and errno values are replaced 42with the 43.Li sys_errlist 44string. Suppressing this feature yields a more consistent 45output format and is easily amenable to further processing. 46.Tp Fl l 47Loop reading end-of-file. 48.Tp Fl T 49Display absolute timestamps for each entry (seconds since epoch). 50.Tp Fl R 51Display relative timestamps (time since previous entry). 52.Tc Fl t 53.Ws 54.Ar trstr 55.Cx 56See 57.Fl t 58in 59.Xr ktrace 1 . 60.Tc Fl f 61.Ws 62.Ar trfile 63.Cx 64See 65.Fl t 66in 67.Xr ktrace 1 . 68.Tc Fl m 69.Ws 70.Ar maxdata 71.Cx 72Display at most 73.Ar maxdata 74bytes when decoding i/o. 75.Tp 76.Sh SEE ALSO 77.Xr ktrace 1 78\- enable kernel process tracing. 79.Sh HISTORY 804.4 BSD. 81
