How to choose the RIGHT PID?
I can find a single PID and copy it to a variable (thanks to the forum), but I have a slightly tougher situation:

When a user logs into our system, it creates 5 processes

example:
Code:
root     21160  3096  0 07:16 ?        00:00:00 sshd: cs113 [priv]
cs113    21164 21160  0 07:16 ?        00:00:00 sshd: cs113@pts/23
cs113    21165 21164  0 07:16 pts/23   00:00:00 -bash
cs113    21186 21165  0 07:16 pts/23   00:00:00 -bash
cs113    21195 21186  0 07:16 pts/23   00:00:01 rtssyn SYNDRV CS

Sometimes, the user gets logged in multiple times and the system won't let them back in. I want to write a script to identify the PIDs of the user and kill them, so they can log back into the system. To do this currently, I am manually grepping for the PIDS using:

Code:
ps -ef | grep cs113

and I get the result posted in the example. I then proceed to kill the process for cs113 that is owned by root to kill the user's login. example from above:

Code:
kill 21160

Depending on how many logins are in the system, I have to manually kill multiple PIDs.

Again, is there a way to automate the process?

       is added to the sulog file.

       Each entry in the sulog file is a single line of the form:

	      SU date time
	      result port user-newuser

       where

       date	       The month and date su(1M) was executed.	date is displayed in the form  mm/dd where  mm is the month number and dd  is  the
		       day number in the month.

       time	       The  time   su(1M) was executed. time is displayed in the form  HH/MM where  HH is the hour number (24 hour system) and	MM
		       is the minute number.

       result	       The result of the  su(1M) command.  A ` + ' sign is displayed in this field if the su attempt was successful; otherwise	 a
		       ` - ' sign is displayed.

       port	       The name of the terminal device from which  su(1M) was executed.

       user	       The user id of the user executing the  su(1M) command.

       newuser	       The user id being switched to with  su(1M).

       SU 03/02 08:03 + pts/5 user1-root
