User process mode

peterchu — Mon, 17 Jan 2005 21:50:38 GMT

I have the below script to kill the user who idle for 180 minutes, it work fine , if I want to have one more checking - if the process is in "Runing" mode not in "Sleep" mode , then the process will not be killed ( that mean only kill the "Sleep" mode process ) could suggest how can I modify the script ? thx.

set -x
for user in `who -u | awk '{ print $6":"$7 }' | grep -v "\."| awk -F : '{ print ($1*60)+$2":"$3 }'`
do

time=`echo $user | awk -F ":" '{ print $1 }'`
pid=`echo $user | awk -F ":" '{ print $2 }'`

if [[ $time -gt 180 ]]
then
kill -1 $pid 2 >> /dev/null
fi

Hi,

You can add to your script :

state=`ps -el |grep $pid | awk '{print $2}'
if [[ $state == S ]] #compare string
then

kill...

fi

Could you show me the log file (>> /tmp/log, not null).
you change to ps -efl (not ps -el)

Sorry, I give you the incorrect script. I was confused about comparation string in shell script and because my internet be disconnected so I post this script not sooner for you. This is the correct

set -x
for user in `who -u | awk '{ print $6":"$7 }' | grep -v "\."| awk -F : '{ print
($1*60)+$2":"$3 }'`
do

time=`echo $user | awk -F ":" '{ print $1 }'`
pid=`echo $user | awk -F ":" '{print $2}'`
state=`ps -el |grep $pid | awk '{print $2" "$4}'| grep $pid | awk '{print $1}'` #catch pid state

if [ $state=S ] #compare string
then
if [[ $time -gt 180 ]]
then
kill -1 $pid >> /dev/null
fi
fi
done

Peter,

Keep in mind that you are looking only at a snapshot of the process table when you do a 'ps'. All process sleep while waiting for their CPU time-slice, so the chances of your script finding a user's sleeping process is quite high. But since you are also defining the idle time limit at 180 minutes, the state of the process is somewhat of a moot point.

Just my 2cts worth,
Mark
