title: How to find the heap memory usage of a process?
body: <p>I would like to find out the size of heap memory being used by a process. I used the following command, which gives <em>some</em> information about heap memory, but it is unclear if it produces the result I am after. </p>
  
  <pre><code>\$ fgrep '[heap]' maps
  
  01538000-01ce2000 rw-p 00000000 00:00 0                                  [heap]
  </code></pre>
  
  <p>I would appreciate your help. Thanks.</p>
