Watching how much memory is being used?

I was wondering if there was a way in Redhat Linux 8.2 to watch how much memory is being used by each process?

$ top
in a terminal window

Note that top will give you wildly misleading figures. It's actually not as simple as you might think.

If you mean "per process" stats, have a look at software.senko.net, look for "procstat", or just "string /proc/<PID>/status". If you want overview stats, look at Freshmeat for "atsar".
Mhearn, you mean shared memory issues?

Hi, I was wondering if there was a way to see how much memory a process has used during its existence.

An example, I run a make file, and when it is finished, I would like to know the specifics of what that file required from my computer and memory. Any way of knowing this??

There is also a memory monitor in gkrellm, but I don't know if it will give what you want.
