How to produce a core

[gshan <gshan@alcatel-lucent.com>]

This morning, I tried command "kill -7 [pid]" but didn't see the core 
file. Anybody has ideas?

bash-2.05b# ps
PID   USER     COMMAND
   1 0        init  
   2 0        [ksoftirqd/0]
   3 0        [watchdog/0]
   4 0        [events/0]
   5 0        [khelper]
   6 0        [kthread]
  36 0        [kblockd/0]
  38 0        [kseriod]
  50 0        [pdflush]
  51 0        [pdflush]
  52 0        [kswapd0]
  53 0        [aio/0]
 171 0        -sh
