Hi,

In addition,

# file core

If it is a system crash dump, use q4.

Hope this helps. Regards.

Well, if "file core" or "strings core" gives you the info you need, you need not venture any further.
But if you need to backtrace to the line of code that caused the core dump, then you'll need a debugger like gdb, xdb or adb. There should be some threads in this forum dealing with the usage of debuggers.

I would definitely use 'file core' over strings, as the latter will give you all the "standard text" as well. That will give you the name of the program that left the core file and the signal it went down on.
If you have toe source code and have compiled it with debugging info you can use gdb to debug the program.
