MY PROCESS CORE-DUMPED BECAUSE OF WHICH SIGNAL?

[Nish]

I have the coredump of my process that crashed.  Is there any unix
utility/program or option in gdb that can be used just to find out as
to the process core-dumped because of which signal?
I do not want to use gdb to read the entire core-file.

If this is not the correct group to post to and if someone could guide
me to the correct group, I would appreciate it.

Thanks,
Nish.
