NAME    [Toc]    [Back]

     trcore - truncate a crash vmcore dump of the operating system

SYNOPSIS    [Toc]    [Back]

     /etc/trcore -f file1 -t trunc_level  [ -o file2 ] [ -v ]

DESCRIPTION    [Toc]    [Back]

     trcore will truncate file1	or copy	file1 to file2 truncated to
     trunc_level.  If file2 is not supplied, then file1	is truncated in	place.
     There is a	three second delay after the warning message is	printed	to
     abort the operation. Aborting any time before the end of execution	will
     leave file1 intact. The resulting file ( file1 or file2) will be
     equivalent	to a crash vmcore dump written at a lower dump level. The
     equivalent	dump level is specified	by trunc_level.

     The following options apply to trcore:

     -f	  Specifies the	input file to process. This file is truncated in place
	  if -o	is not specified. This is a required parameter.

     -t	  Specifies the	equivalent dump	level to truncate the file to. This is
	  a required parameter.

     -o	  Specify an output file. If this parameter is supplied, then the
	  input	file is	left intact and	the output file	is truncated.

     -v	  Provide extremely verbose output. Operation is silent	otherwise.
	  Mostly useful	for debugging crash vmcore dumps.

DIAGNOSTICS    [Toc]    [Back]

     The program may print "trcore: short read:	Error 0" if the	input file is
     not a complete dump. The program will still have performed	normally.
