Shell Programming and Scripting

Hi All,

I have to kill a program whose pid, i will be getting.

Multiple processes will be getting started by my script of same kind in a series.

So for after each call to a process i need to write a command or script which can kill the process if it takes more than 5min. In this i will be providing the pid to this command or script.

Is there anyway or command to perform the same? It would be helpful if it is going to be a single command.

This task has to be performed using Perl.

Thanks,
Nishank

if u get the pid already u can use system command of perl to run a system command

system("kill -9 $pid");

Is this is what u r looking for ? How are you calculating the running time of the process ?

Code:

 
watchproc()
{
pid=$!
count=0
while `ps $pid > /dev/null`
do
  if [ $count -gt 300 ]  # 5mins = 300 sec
  then
    echo "killing process $pid"
    kill -9 $pid
  fi
  sleep 1
  count=$(( $count + 1 ))
done
}
tail -f /var/log/messages &
watchproc
