How to assign a string?
<p>I have this command for wake on the system <code>os.system('sudo sh -c "echo date \'+%s\' -d \'+ 24 hours\' &gt; /sys/class/rtc/rtc0/wakealarm"')</code>. After executing this command i just open wakealaram file. It is empty, nothing is written.</p>

<ol>
<li>Why is it empty, shouldn't it write some date?</li>
<li>How to give a manual date to wakealaram instead of system date + 24 hours?
eg:date = "2147472000"</li>
</ol>

<p>Would <code>os.system('sudo sh -c "echo date &gt; /sys/class/rtc/rtc0/wakealarm"')</code> work?</p>
