Hi,

I'd like to know how to find which program produced a particular core dump
file, any idea?

thanks,

$ file core_file

for further analysis see also options relative to core dumps under ..

$ man gdb

Thanks,

May I suggest using the 'file' command?

$ baz
Segmentation fault (core dumped)
$ ls
baz core
$ file core
core: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV),
SVR4-style, from 'baz'

Strangely, it doesn't work on my system:

omer@pc-cedric:~$ file core
core: ELF 32-bit LSB core file Intel 80386, version 1 (SYSV), SVR4-style

But gdb -batch did the trick, thanks!
