Debian init.d startup & shutdown scripts

[stokes]

I'm writing a little script using instructions from here to start and stop some bits and pieces when my system boots.

#! /bin/sh
# /etc/init.d/bensbits
#

# Carry out specific functions when asked to by the system
case "$1" in
  start)
    echo "Starting PostgreSQL"

su postgres
/usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data >/tmp/logfile 2>&1 &
exit

    echo "Starting PHP DNS Updater"

php updateip.php >/dev/null &

    ;;
  stop)
    echo "Stopping script blah"
    echo "Could do more here"
    ;;
  *)
    echo "Usage: /etc/init.d/bensbits {start|stop}"
    exit 1
    ;;
esac

exit 0

My question is, how can I gracefully end the processes I started? I know I can use ps | aux to get the process numbers and then kill them, but how can I automate this?

The easier thing might be to use the killall command. It kills processes by name rather that PID.

So if this is my process:

ps aux | grep php
root     22308  0.0  0.5   8200  2332 ?        S    Apr19   0:00 php updateip.php

Would this work?

killall "php updateip.php"

Ooh, that's a tricky one, huh? I don't know if it would just kill the ipupdate thing, or all things related to php, or nothing at all. You might have to give the killall command a "live" test-run to see if it does the right thing.
