User profile

Sorry to I am not familiar with script writing ,

attach is the /etc/profile in my system , we have limit each user can only have one login in the system . When the user login , if the system found the user have a dead process in the system , the system will confirm the user to kill the previous login and try to kill it ( this is the additational function of the profile ) , but I have a problem now , the system can't kill the previous dead process now , I think it is because the system only try to kill the PID , but not the PPID ,so it will pop the "not the process owner" when trying to kill the process , could suggest how can I change the script so that it will kill the PPID ? or is there any reason why the dead can't be killed ? thx in advance.

kill(1) 						      General Commands Manual							   kill(1)

Name
       kill - send a signal to a process

Syntax
       kill [-sig] processid...
       kill -l

Description
       The command sends the TERM (terminate, 15) signal to the specified processes.  If a signal name or number preceded by `-' is given as first
       argument, that signal is sent instead of terminate.  For further information, see

       The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot  be  caught.
       By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are
       signaled.  This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser.

       The process number of an asynchronous process started with `&' is reported by the shell.  Process numbers can also be  found  by  using	It
       allows job specifiers ``%...''  so process ID's are not as often used as arguments.  See for details.

Options
       -l   Lists  signal  names.  The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG
	    prefix.
