title: Finding out if a binary file has been compiled with stack smashing protection
body: <p>On a Linux, is there any way to tell if a binary file has been compiled with stack-smashing on/off from the command-line?</p>
  
  <p>I am pretty sure that I have the protection on, but just for the sake of sanity, I'd like to write some tests for my binaries in case there ever comes a day when everything goes wrong and the protection is off... for some reason.</p>
