    Dear managers,

    thanks for the overwhelming response.

    "Mike Demarco" <mdemarco@tritonpcs.com>
    Reggie Beavers <reggiebeavers@fstha.com
    Tony_Schloss@ao.uscourts.gov >
    "Simon Phillips" <Simon.Phillips@uhi.ac.uk>
    "Skip Hammack" <skip.hammack@starband.net>
    "MURAT BALKAS" <murat.balkas@rtnet.net.tr>
    "Gurugunti, Mahesh" <MGurugunti@us.nomura.com>

    The easiest solution was suggested by Tony Schloss and looks as follows:

    > #!/bin/sh
    >
    > if [ ! `/usr/bin/pgrep OurService` ] ; then
    > nohup ./OurService &
    > fi
    >
    > exit 0

    Others suggested to use inittab or respawn (see man pages). I will try
    that as well. However, since in the general case I need to path
    parameters the avove script/crontab seems the best.

    Thanks a lot,

        Andreas

    The questions was as follows

    Dear managers,

    we have a service process running in the background that unfortunately
    dies from time to time. We are researching why. However, until we have
    found the bug we would like to setup a script that is called by cron
    every 5 mins. This script should check whether the process is still
    running with something like

    ps -Af | grep OurService

    and if it is not then restart it with

    nohup ./OurService &

    I have no idea how such a shell script would look like. Ideas are
    greatly appreciated.

    Thanks ins advance!

    Regards,

        Andreas
