notification upon program completion
<p>I'm going to run prog.cpp on my university's Linux cluster (compiled with gcc). I project that the program will take 3-6 days to complete. I was thinking of running it as</p>

<pre><code>./prog &amp;
</code></pre>

<p>to run it in the background. My questions are:</p>

<ol>
<li>Is it safe for me to just close the terminal window?</li>
<li>How do I know when my program is complete? Can I make GCC notify me somehow?</li>
</ol>
