How do I change the kernel template for a specific application only?

man core

tells us:

Resetting the underlying pipeline server to the program

Since kernel 2.6.19, Linux supports an alternative syntax for       /proc/sys/kernel/core_pattern

. If the first character of this file is a pipe character ( |

), then the rest of the line is interpreted as executable. Instead of a disk file, the kernel dump is listed as standard input to the program.

Pay attention to the following points:

• The program must be specified using an absolute path (or root path, /) and it must immediately follow the '|' character character.

• The process created to run the program runs as user and group root.

• Command line arguments can be supplied to the program (since Linux 2.6.24), delimited by a space (up to a total line length of 128 bytes).

• Command line arguments can include any of the% specifiers listed above. For example, to pass the PID of the process that is being dumped, specify% p in the argument.

You can put a script there like

| /path/to/myscript %p %s %c

      

        
        
        
      

    

You can determine which process is running the coredump: ( man core

):

       %%  a single % character
       %p  PID of dumped process
       %u  (numeric) real UID of dumped process
       %g  (numeric) real GID of dumped process
       %s  number of signal causing dump
       %t  time of dump, expressed as seconds since the Epoch,  1970-01-01
           00:00:00 +0000 (UTC)
       %h  hostname (same as nodename returned by uname(2))
       %e  executable filename (without path prefix)
       %E  pathname of executable, with slashes ('/') replaced by exclama‐
           tion marks ('!').
       %c  core file size soft resource limit of crashing  process  (since
           Linux 2.6.24)

      

        
        
        
      

    

Now all you have to do is "execute the default task" for processes other than your own
