I was trying to do this for a little while so in case anyone's interested, here it is. Most of the code was kindly sent to me by other people so do not blame me for the mistakes. This script(auto) checks ZOPE every 15'th minute and if it does not run, it will restart it. It has been working without a problem on FreeBSD 4.0 after I patched ZOPE's pidfile for LF's. (without that little operation it returns an error message and restarts ZOPE every time without checking it) I am running this from crontab: SHELL=/bin/sh 0,15,30,45 * * * * /home/user/auto And this script(auto) is sitting in my user directory: #!/bin/sh ZOPEDIR="/home/user/zope" INFOMAIL="mail@okstudio.com.au" STARTFILE="$ZOPEDIR/start" STOPFILE="$ZOPEDIR/stop" PIDFILE="$ZOPEDIR/var/Z2.pid" PID1ACTIVE=0 PID2ACTIVE=0 if [ -x $STARTFILE ]; then if [ -r $PIDFILE ]; then PID1=`cut -d" " -f1 $PIDFILE` PID2=`cut -d" " -f2 $PIDFILE` if kill -0 $PID1 2>/dev/null then PID1ACTIVE=1 fi if kill -0 $PID2 2>/dev/null then PID2ACTIVE=1 fi fi if [ $PID1ACTIVE -eq 0 -o $PID2ACTIVE -eq 0 ]; then $STOPFILE >/dev/null 2>&1 sleep 10 $STARTFILE date | mail -s"Zope restarted" $INFOMAIL >/dev/null 2>&1 fi fi Regards, George
