I don't have "Process" header I'd like to run an application on my system after pushing a button on an Arduino shield. I've read that I need to use the runShellCommand() function, which can be accessed from a Process header. However when I add the #include &lt;Process.h&gt; line to my program I'm getting this error:

.build/uno/src/sketch.cpp:2:21: fatal error: Process.h: No such file or directory
 #include &lt;Process.h&gt;


I'm using Ubuntu 14.04 and I've installed Arduino software from repositories.
That only works on an Arduino Yún (as described in this tutorial).
