<script type="text/html" data-help-name="daemon">
<p>Calls out to a long running system command. Sends <code>msg.payload</code> to stdin of the process.</p>
<p>Provides 3 outputs... stdout, stderr, and return code , from the running command.</p>
<p>Parameters can be space separated, space separated with quotes, or a javascript array. For example `aa bb` or `"cc dd"` or `["aa","bb cc""]`.</p>
<p>If the called program stops (i.e. a return code is produced), this node can attempt to restart the command.</p>
<p>Setting <code>msg.kill</code> to a signal name (e.g. SIGINT, SIGHUP) will stop the process - but if the
restart flag is set it will then auto restart. Sending <code>msg.start</code> will also re-start the process.</p>
