One good article on the subject is at http://www.ibm.com/developerworks/linux/library/l-linux-memory.html They talk about using the "free" command to look at your memory. Although you can add a <code>-s</code> switch to redo the command every so many seconds, this will just run output scrolling through your console, so the better option would be to use <code>free</code> in tandem with <code>watch</code> which has the added benefit of being capable of highlighting the differences for you. | One good article on the subject is at http://www.ibm.com/developerworks/linux/library/l-linux-memory.html They talk about using the "free" command to look at your memory.
