title: Howto symlink Python to Python2.7 as non-superuser
body: <p>I am a non-superuser of a linux machine. 
  Currently it has 2 versions of Python.</p>
  
  <p>When I invoke standard <code>python</code> command it gave version 2.6</p>
  
  <pre><code>$ python
  [neversaint@mach71 ~]$ python
  Python 2.6.2 (r262:71600, Jan 28 2011, 13:47:39) 
  [GCC 4.1.2 20080704 (Red Hat 4.1.2-48)] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; 
  
  $ which python
  /opt/somedir/bin/python
  </code></pre>
  
  <p>It's only when I invoke with <code>python2.7</code> it gives the version 2.7</p>
  
  <pre><code>[neversaint@mach71 ~]$ python2.7
  Python 2.7.6 (default, Nov 11 2013, 13:13:15) 
  [GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux2
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt;
  
  $ which phython2.7
  /usr/bin/python2.7
  </code></pre>
  
  <p>My question is how can I set it such that whenever I call <code>$ python</code> it will give me version 2.7.</p>
