core dump; kill - ??

[Shivkumar]

Dear Sirs,

Which number along with "kill -? PID" command would produce a core dump file ?

Thanks,
Shiv

kill -3 $PID will do that, have a look at the man pages of kill and kill -l command

Yes kill -3 will terminate with core dump; can be trapped

Hi,

I know the -3 option on kill command. It is the known option to obtain it.
However keep in mind the option -6 even if it is undocumented.

I had a problem with a java process and I launched successfully

kill -6

in order to obtain core dump.
I think it depends if the process to be killed produces output (for that -3 option) or it is a process which doesn't provide output (for that -6 option should work).

Usually I saw -6 used for core dump java processes.

Hope this helps you.

Best regards,
Fabio

See signal 5 man page. Signal with Action ii will create Core files.
