title: Export PYTHONPATH - syntax error
body: <p>I need to connect MySQLdb - module.</p>
  
  <p>I download MySQLdb - module and install it. </p>
  
  <p>But when i write (in python interactive shell): <code>import MySQLdb</code> - i get <code>no module named MySQLdb</code>.</p>
  
  <p>Then i decided to include MySQLdb directory in PYTHONPATH variable.</p>
  
  <p>I write (in python interactive shell): 
  <code>export PYTHONPATH=${PYTHONPATH}:/where/module/lives/</code></p>
  
  <p>And in response i receive a syntax error: <code>invalid syntax</code>: export PYTHONPATH<code>^</code>=${PYTHONPATH}:/where/module/lives/</p>
  
  <p>What's wrong with syntax here?</p>
