I have correction with the script but still doesn't work:
#!/usr/local/bin/bash
for user in `ps -A -o user | sort | uniq | tail +2`
do
echo "user: $user"
ps aux -U $user | tail +2 | while read line
do
mem=`echo $line | awk {'print $4'}`
echo "mem: $mem"
TMPSUMMEM=`awk -v x=$mem -v y=$TMPSUMMEM 'BEGIN{printf
"%.2f\n",x+y}'`
echo "summem: $TMPSUMMEM"
done
echo "finalsummem: $SUMMEM"
export SUMMEM=$TMPSUMMEM
done
echo "finalsummem: $SUMMEM"
