title: Python - When Is It Ok to Use os.system() to issue common Linux commands
body: <p>Spinning off from another thread, when is it appropriate to use os.system() to issue commands like rm -rf, cd, make, xterm, ls ?</p>
  
  <p>Considering there are analog versions of the above commands (except make and xterm), I'm assuming it's safer to use these built-in python commands instead of using os.system()</p>
  
  <p>Any thoughts? I'd love to hear them.</p>
