I am sending a script that kill users with IDLE more than 30 min.

Code:

#!/bin/ksh
# ====================================
# Function   :  Kill Inactive Users
# Author      :  Witt
# Date         :  01/07/16
# ====================================
#
# begin
#
#----------------------------------------------
# Variable declaration
#----------------------------------------------
cmd=w

cmd1() {
awk 'substr($0,34,1) >= 3 { print $0 }'
}

#----------------------------------------------
# Format output
#----------------------------------------------
echo "The following users are inactive more than 30 min..... :"
echo " "
#${cmd} | head -2 | tail -1
${cmd} | cmd1
tot=`${cmd} | cmd1 | grep pts\/ | wc -l`
echo " "
echo "Total of Users with idle more than 30 Min. : ${tot}"
echo ""

#----------------------------------------------
# Kill users with idle more than 30 min
#----------------------------------------------
for i in `${cmd} | cmd1 | grep pts\/ | awk '{print $2}'`
do
fuser /dev/$i > /tmp/$$killusers 2>/dev/null
    for proc in `cat /tmp/$$killusers`
    do
    kill -15 $proc
    done
done
rm -f /tmp/$$killusers
#
# end

I hope help you

kill

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.
