back into this again
I'm back into this issue again.
What I want to do:
I need to identify processes that have reverted to PPID 1 for a specific user.
I need to kill all the processes that are over 2 hours old that have reverted to PPID 1.
I have used the grep command and stored the processes in a file.
I can identify processes over a day old by looking for the Month in the date field.
I'm having a problem getting the hour logic to work.
Can anyone help me on this?
currHR=`date +%H`
echo $currHR
LastHr=`expr $currHR - 1`
echo $LastHr
#
cat $TMP2 | while read b
do
ProcessTime=`echo $b | awk '{print $5}'`
ProcessHour=`echo $ProcessTime | awk -F: '{print $1}'`
Killid=`echo $b | awk '{print $2}'`
echo "ProcessTime " $ProcessTime
echo "ProcessHour " $ProcessHour
case $ProcessTime in
M*|J*|F*|A*|S*|O*|N*|D* ) echo $ProcessTime "Day old " ;;
* ) case $ProcessHour in
$currHR) echo "current hour " ;;
$LastHr) echo "last hour ";;
esac
echo $ProcessTime "other " ;;
esac
done
The logic recognizes currHR as 08 (etc)
The logic recognizes LastHr as 7 (etc)
The logic recognizes ProcessHour as 07, 08 (etc)
The 2nd case logic for processhour does not match current or last hour.
