how do you cause a running pocess to dump a core file on linux systems??

i tried
sleep 100 &
kill -SEGV PID

but nothing is created

also, what commands can be used to analyze them? (extract useful info from them)

I think most (all?) Linux distributions have disabled generation of core files.

Try to "ulimit -c" and see if it outputs 0 (On my SuSE Linux it is 0). It should return the maximum size of core files generated. You can "man ulimit" and see how to set it to a non-zero value.
