You should use the wait command ie
Code:
# start a background task that takes some time
sleep 10 &

# returns immediately with process id of background task

# now wait for it to finish all background tasks
wait
but if it was me then I'd just alter the initial script so it mails your group when it finishes.

Like Mike said just mail the output from your script e.g.
myjob.sh | tee myjob.log | mailx -s 'myjob.log' myteam@myoffice.com &

If they haven't said thank you after this amount of time then it's probably not worth helping them any more.

Sorry for the dealay. I really appreciate your effort on this.

If I start any process or script in unix. I will get the process number. To know the status of the process, we used the command ps -ef |grep process_number.
Instead of doing this. We need to automate the process by send an auto mail once the job or process is completed.

Thanks

We are writing every activities of job or script in the log. but we need to open the log and see the activity of script, wheather the script is completed or not.

My expectation is simple. I just start run the unix script. It will take 3 to 4 hours to complete. Once the script is completed.I need to get a mail that so and so script is completed, please veryfy the logs...

Once again I thank for all you folks

What did you NOT understand about Mike's and pdreyer's solution?

Adding to those alternatives, you could just add code at the end of the script to e-mail the log:

Code:

#!/bin/ksh
# this is myScript.sh
#
LOG_FILE=/path/to/logs/myScript.log
#
dosomething.sh >$LOG_FILE
if [ $? -ne 0]
then
  cat $LOG_FILE| mailx -s "$0 !ERROR, something happened." oper@mydomain.com
  exit 1
fi
#-- Etc --
dosomethingelse.sh >>$LOG_FILE
#-- Etc --
# At end of the script add:
cat $LOG_FILE| mailx -s "$0 All OK!" oper@mydomain.com
exit 0

shijoe.

When the task is initiated, the process id gets known.

I also understand that

Now, write a loop that reads `ps` and greps for the process id. So long as the lines returned are > 0, then it is running.

while
do
loop
done
cat logs | mail x ....
The script needs to be refined to handle exceptions etc but is a fairly common text book example.

End

Yes, this script is nonsense. It should look more like Mike's, pdreyer's or my
solution.
