Need help in a script !

I have a script that found muliple same process running in the background and then kill thems all and re-start a new process.Below the script in k-shell

Code:

#!/bin/ksh
p=`date +"%Y-%m-%d"`
b=1

for i in LookupLoader
do
a=`ps -aef | grep java | grep "$i" | wc -l`

if [ $a -gt $b ]
then
echo "$a instances of $i is running"

for j in `ps -aef | grep java | grep "$i"`
do
PID=`$j | awk '{print $2,$3}'`
kill -9 $PID
done

else
echo "No Nultiple instances"
fi

done

The inner "for loop" is not working , here the reason for "FOR LOOP" is that i want to get the PID ID of process let say "LookupLoader" one by one and then kill them .

But "for loop" is working wrong here. The basic idea is to get the pid id of lookuploader and kill them one by one

Please any new suggestion would be helpfull !

Below the info along with pid for "LookupLoader"

Code:

pipe 2031752 2814188   3 00:46:02  pts/1  0:10 java -D_AppName=LookupLoader com.eMeter.PIPe.cleaner.CleanerLoader /home/pipe/conf/appProperties/LookupLoader.properties 

pipe 2543622 2715826   2 00:05:21  pts/1  0:15 java -D_AppName=LookupLoader com.eMeter.PIPe.cleaner.CleanerLoader /home/pipe/conf/appProperties/LookupLoader.properties

kill

KILL(1) 							   User Commands							   KILL(1)

NAME

       kill - send a signal to a process

SYNOPSIS

       kill [options] <pid> [...]

DESCRIPTION

       The  default  signal  for kill is TERM.	Use -l or -L to list available signals.  Particularly useful signals include HUP, INT, KILL, STOP,
       CONT, and 0.  Alternate signals may be specified in three ways: -9, -SIGKILL or -KILL.  Negative PID values may be  used  to  choose  whole
       process	groups;  see  the  PGID  column  in ps command output.	A PID of -1 is special; it indicates all processes except the kill process
       itself and init.

OPTIONS

       <pid> [...]
	      Send signal to every <pid> listed.

       -<signal>
       -s <signal>
       --signal <signal>
	      Specify the signal to be sent.  The signal can be specified by using name or number.  The behavior of signals is explained  in  sig-
	      nal(7) manual page.

       -l, --list [signal]
	      List signal names.  This option has optional argument, which will convert signal number to signal name, or other way round.

       -L, --table
	      List signal names in a nice table.

       NOTES  Your shell (command line interpreter) may have a built-in kill command.  You may need to run the command described here as /bin/kill
	      to solve the conflict.

EXAMPLES

       kill -9 -1
	      Kill all processes you can kill.

       kill -l 11
	      Translate number 11 into a signal name.

       kill -L
	      List the available signal choices in a nice table.

       kill 123 543 2341 3453
	      Send the default signal, SIGTERM, to all those processes.

SEE ALSO

       kill(2), killall(1), nice(1), pkill(1), renice(1), signal(7), skill(1)

STANDARDS

       This command meets appropriate standards. The -L flag is Linux-specific.

AUTHOR

       Albert Cahalan <albert@users.sf.net> wrote kill in 1999 to replace a bsdutils one that was not standards  compliant.   The  util-linux  one
       might also work correctly.
