Need a script to kill processes with PPID of 1
Hi,
I have been trying to come up with a script to run as a cron job to kill any processes that have PPID of 1. I have created a file that contains the PID and the PPID. How can I read this file and then execute a kill on any PID where PPID is 1. The file looks like this:

4904 1
4455 1
6561 6560
5678 1

I create the file using:
ps -ef|grep -v root|grep rp_h1|awk '{print $2 , $3}' > killog

Then I want to read the killog file and issue a kill -9 on each PID that has a PPID of 1. This seems like it should be simple, but I am not very good with script writing. Thanks in advance for your help!!!

kill.d

kill.d(1m)							   USER COMMANDS							kill.d(1m)

NAME

       kill.d - snoop process signals as they occur. Uses DTrace.

SYNOPSIS

       kill.d

DESCRIPTION

       kill.d is a simple DTrace program to print details of process signals as they are sent, such as the PID source and destination, signal num-
       ber and result.

       This program can be used to determine which process is sending signals to which other process.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       Default output, print process signals as they are sent.
	      # kill.d

FIELDS

       FROM   source PID

       COMMAND
	      source command name

       TO     destination PID

       SIG    destination signal ("9" for a kill -9)

       RESULT result of signal (-1 is for failure)

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

       kill.d will run forever until Ctrl-C is hit.
