title: Exit value from java.lang.Process#waitFor()
body: <p>The method <a href="http://docs.oracle.com/javase/7/docs/api/java/lang/Process.html#waitFor%28%29" rel="noreferrer">waitFor()</a> returns an integer value which is the return code. The value 0 indicates normal termination. But what are the meanings of other return codes? I am getting an exit value 11. What does that mean? And where all the exit value codes are documented?</p>
