What's the best way to determine the most memory a program uses
during its execution?

Thanks!

Depending on how accurate of data you need, usually top or ps will do
the trick. If you want more data than just eye balling top, run ps in
a shell script to have it poll the process every couple of
seconds/minutes too see how much memory it is using. With a command of
ps -o vsz,rss <pid> you can get a good idea of these values.

Also, if you wanted in another shell you could run watch -n 5 "ps -o
vsz,rss <pid>" which will run the command every 5 seconds.

Hope this helps!
Chris
