You should really fix the tool so it doesn't die.

However, if the process doesn't fork into the background you can write a simple loop in a script:

#!/bin/ksh

while [ COBOL_STILL_EXISTS ]
do 
   yourTool  // Do not put it in the backgroun with 
done

Similarly, a shepherd process can be in the same sort of infinite loop, ps | grep for the process name, then if $? != 0, restart the tool in the background.

The actual script is left as an excercise.

Also, there are several tools that do just that sort of think for you, Big Brother is one of them, but is quite a setup task.

So many choices here but one simple script could be:

#!/bin/csh
set $logfile="/var/log/restart.log"
foreach DAEMON ( application1.pl another1.pl exim ldap_auth)
ps -e | fgrep "$DAEMON:t" | cut -c1-8 > /dev/null
if ( $status > 0 ) then
echo "Restarting $daemon at:" >> $logfile
date >> $logfile
$DAEMON &
endif
end

Not tested exact syntax and things taht require arguments on the startup will need to be added to the start script so it may need a tweak here and there.

Good Luck
