What command can I use to see the memory usage by application

I am having an issue with a process / application using up memory over time. The server bogs down over a couple of month period and has to be rebooted.
Thanks Ed

You said "a process" so you know which one it is?

No, it is what I want to discover, which process / application is it. So if I can get the memory information from the system on a regular basis, like once a day I should hopefully be able to identify which process / application is not releasing the memory. That is why I want to know what command will give me the usage by process / application.

Top will do. You can run it as a batch command (so as to pipe its output to a file) as well as specifying the refresh interval with the -b and -d switches respectively.

Perfect, this will give me what I'm looking for. Thanks

htop is good also, it has some sorting options that top does not.
