Bash scripting

can anyone help on the following problem.


System Configuration : SunOS sun210 5.9
-----------------------------------------


I have two scripts "Master and Restart" script.

- From the master script , I have to start, stop the restart script on certain conditions.

- To achieve the above functionality, I need to get the processID of the restart script. But when i try the following script I am not able to get the processId.

Sample Master Script
====================

./restart.sh &

while true; do
if [ check for some condition ]
then
restartId=`ps -ef | grep "restart.sh" | grep -v "grep" | sed /zap/d | cut -c10-15`
if [ -n "$restartId" ]
then
echo "Killing the restart script"
kill -9 $restartId
fi
fi
sleep 1
done



- When I manually tried to '$ Ps -ef | grep restart.sh' , I could not see any process running.

Is there any better and efficient way to do the above.

Thanks and Regards,

hi,

i've had to do something similar in the past a few times.

i ended up getting the script that was being checked for to echo it's process id ($$) to a log file, and the master script then read that process id from the file...

feels like a bodge, but it worked a treat

if i understand your probl, you need a prog
- starting something if not still running
- stopping something if running
- restart (this is stopp+start) something
do it!
1) it's running ?
2) yes: exit, no: start!
3) required restart? kill it and restart this script

btw: forget this stupidity
restartId=`ps -ef | grep "restart.sh" | grep -v "grep" | sed /zap/d | cut -c10-15`
i see you use SVR4 ps
read man pages
ps -efocomm|sed "s?.*$0 ??"
check the output
(at the moment i am not on *nix,
change comm by args if not matching)
