Re: Prologue/Epilogue script

Jeff,

Here is what we use:

#!/bin/ksh

if [ "$1" = "root" ]
then
      echo "$0: cannot kill root!"
      exit 1
fi

if [ -z "$1" ]
then
      echo "$0: kill who?"
      exit 1
fi

HN=$(hostname)

for i in $(ps aux | grep "^$1 " | grep -v grep | awk '{print $2}')
do
      if ps -p $i >/dev/null 2>&1
      then
            echo "killing $HN $i"
            kill $i 2>&1
      fi
      if ps -p $i >/dev/null 2>&1
      then
            echo "KILLING $HN $i"
            kill -9 $i 2>&1
      fi
done

Hope that helps.

I'm assuming that even if you get only 1 core on the node, you "own" the
node
(you may need the memory per core for a code).

You bet!

Thanks!
