title: Meaning of exit status 1 returned by linux command
body: <p>What is meaning of exit status 1 returned by linux command? Like 127 exit status indicates "command not found".</p>
  
  <p>I have visited <a href="http://linux.die.net/abs-guide/exitcodes.html" rel="noreferrer">http://linux.die.net/abs-guide/exitcodes.html</a> page, does it mean exit status 1 does not have particular special meaning?</p>
