Hello all,

I have gone through the search and looked at posting about idle users and killing processes. Here is my question I would like to kill an idle user ( which I can do) but how can I asure that all of his process is also killed whit out tracing his inital start PID. I have tried this on a solaris 8 system but, I seem to make the child process a zombie or hang because of what he was doing. Is there a clean way to do this?
Thanks
I have used the following shell script to kill all child PID's for a given PID.

Code:
#!/bin/ksh
# This script will kill all the child process id for a  given pid
#Store the current Process ID
CURPID=$$

# This is process id, parameter passed by user
ppid=$1

if [ -z $ppid ] ; then
   echo No PID given.
   exit;
fi

arraycounter=1
while true
do
        FORLOOP=FALSE
        # Get all the child process id
        for i in `ps -ef| awk '$3 == '$ppid' { print $2 }'`
        do
                if [ $i -ne $CURPID ] ; then
                        procid[$arraycounter]=$i
                        arraycounter=`expr $arraycounter + 1`
                        ppid=$i
                        FORLOOP=TRUE
                fi
        done
        if [ "$FORLOOP" = "FALSE" ] ; then
           arraycounter=`expr $arraycounter - 1`
           ## We want to kill child process id first and then parent id's
           while [ $arraycounter -ne 0 ]
           do
             kill -9 "${procid[$arraycounter]}" >/dev/null
             arraycounter=`expr $arraycounter - 1`
           done
         exit
        fi
done
## Kill Parent ID
kill -9 $CURPID
