Hi,

        I have a problem in killing all the processes under a process.
        When I try to kill a Parent process, Child process and its
        child process are not being killed. I do manually by checking
        'ps -ef |grep process' and then kill each process and its child
        process individually. It some times consumes lot of time for me
        and also sometimes I will be missing some sub-processes.

        Can  any one help me in issueing a shell command or writing a
        shell script.

        Thank you all in advance for your time.

Thanks & Regards,

If the processes are all part members of a single process group, you can
use the negative of the process group ID to send a signal to all the
processes in the group at once.  Generally, the PGID will be the PID of the
parent process that heads the group.

If that doesn't do what you want, here's a perl script that figures out the
process hierarchy and then kills all the processes destined from a given
process.

#!/usr/local/bin/perl -w

$signal = $ARGV[0];
$top_process = $ARGV[1];

%children = ();
open PROCESSES, "ps -eaf |" || die "$0: open ps: $!\n";
while (<PROCESSES>) {
  next if /^ +UID/; # Skip heading
  my ($pid, $ppid) = /^\s*\S+\s+(\d+)\s+(\d+)/;

kill $signal, $top_process;
&killchildren($top_process, $signal);

sub killchildren {
