Opening other applications using python
<p>I am using Ubuntu 12.04 on a 64bit laptop. I am trying to open an application using python code.</p>

<pre><code>import os
os.system("open /home/utsav/ab.txt")
</code></pre>

<p>It gives the following error:</p>

<p>"Couldn't get a file descriptor referring to the console 256"</p>

<p>What command do I want to use?</p>
