I think I found the command to display my memory usage but I don't
understand the difference between top and ps --user=root -f -u.
The two output are completely different and apparently the processes using
memory are root processes. How can I find out what they are excatly and if I
can stop them from running?
Any help would be appreciated
thanks
Meg
