trcore - truncate a crash vmcore dump of the operating system
/etc/trcore -f file1 -t trunc_level [ -o file2 ] [ -v ]
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.
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.
