Run ur process
ps -e | grep "<process name>" | awk '{print $3}' ---This will give time
compare with ur required time and kill

Thanks for your reply.
but again I will have to kill the process manually with this command if i am understanding this properly.

how will i run this command when i ll run the process? I mean if i run a process, at the same time can i define its duration? or after 5 hours this process automatically killed?

Thanks ....

I have done this ....

see the example ... just wrote a small script


runtime=${1:-1m}
mypid=$$
cp /Database/Client_db_200802110231.BAK .&
cpid=$!
sleep $runtime
kill -s SIGTERM $cpid
echo "Both processes are terminated".

I mean now i can define the running time duration of all processes like cp with the time.

Cheers.

You can kill a process using ulimit by specifying the resources it will have available. The -t option will allow you to specify the max cpu seconds any process run from your shell can use (after which time the process will be killed).

I don't know of a clever way to kill a process after a certain amount of clock time passes. The best thing I can think of at the moment is a simple at job to run the kill command at the time you specify.

edit: Just noticed your kludge using sleep; glad you worked it out.
