Hi all,

I have given a command in the unix machine :

$kk.sh &

kk.sh is running in background process, I want to kill the that
job after 1 minute, I tried to find out the process id, by giving
this command

$ps -eaf |grep kk.sh

nothing I found, so, how can I kill that process ?

please reply to ::email removed::

Thanks

krishna

If the script does not show up in the 'ps' listing, then it must already have completed.

For jobs running in background (invoked with &) -
type jobs at prompt to see all jobs.

You can kill these jobs with "kill -9 %#" where %# is %1 or %2 or whatever the number of the job. (note: % is the percent sign)

When a background job finishes, you should be notified with a "Done" response.

The variable $! will also contain the PID of the last job you invoked in background.

If you invoke kk.sh from within another script:

#!/usr/bin/ksh

kk.sh &
BG_PID=$!
sleep 60
kill -9 $BG_PID

To kill the job after 1 minute.

Also the wait command will return the return code ($?) of the background job as well...

kk.sh &
wait
echo $?
