I have a line in the script that calculates how much memory a certain user occupies:
ram=`ps -u $ID --no-headers -o rss`
The ram variable gets:
echo $ram
29448
18128
61672
29116
35376
How can I add these numbers correctly?

ram=`ps -u $ID --no-headers -o rss | awk '{ sum += $1 } END { print sum }'`
echo $ram
