[Zope] Using crontab instead of rc.d

[KIMMELL]

Hello,

Here's something I put together. I am pretty much clueless when it comes
to bash shell programming, so this may be a really bad way to do things. I
would think you could run this script from your crontab. I tried this on
Redhat 6.2 , so YMMV.

-garrin

-- begin script --

#!/bin/bash
ZOPEHOME=/var/Zope-2.2.0-linux2-x86
DEAD="
"

for pid in `cat $ZOPEHOME/var/Z2.pid`; do
    status=`ps --no-headers -p $pid`
    if test $status == $DEAD; then
        echo "Restarting Zope"
        nohup $ZOPEHOME/start
        break;
    fi
done       

-- end script --
