                     32: displays kernel trace files produced with
                     33: .Xr ktrace 1
                     34: in a human readable format.

                     38: .Nm kdump
                     39: reads the file
                     40: .Sq Pa ktrace.out
                     41: in the current

                     47: Display all numbers in decimal.
                     48: .Tp Fl n
                     49: Suppress ad hoc translations.  Normally
                     50: .Nm kdump
                     51: tries to decode many
                     52: system calls into a more human readable format.  For example, ioctl
                     53: values are replaced with the macro name and errno values are replaced
                     54: with the
                     55: .Li sys_errlist
                     56: string.  Suppressing this feature yields a more consistent
                     57: output format and is easily amenable to further processing.
                     58: .Tp Fl l
                     59: Loop reading end-of-file.

                     61: Display absolute timestamps for each entry (seconds since epoch).
