Can you tell me what is heap in Linux ?

Using ``ps -auxw'' | head -5

    USER   PID %CPU %MEM   VSZ   RSS  TT STAT  START   TIME COMMAND

To my knowledge (but man ps will tell you more), VSZ is the virtual
size (not yet committed, or paged out), and RSS is the actual physical
RAM usage, including stack.

You can get more detailed information that way, and with man 5 proc
