[from a post I made frequently in comp.unix.questions...]
No no no. Don't use kill -9.
It doesn't give the process a chance to cleanly:
1) release IPC resources (shared memory, semaphores, message queues)
2) clean up temp files
3) inform its children that it is going away
4) reset its terminal characteristics
and so on and so on and so on.
Generally, send 15 (SIGTERM), and wait a second or two, and if that
doesn't work, send 2 (SIGINT), and if that doesn't work, send 1
(SIGHUP). If that doesn't, REMOVE THE BINARY because the program is
Don't use kill -9. Don't bring out the combine harvester just to tidy
up the flower pot.
