<script type="text/x-red" data-help-name="exec">
|
|
<p>Calls out to a system command.<br/></p>
|
|
<p>Provides 3 outputs: stdout, stderr, and return code.</p>
|
|
<p>By default uses the <code>exec</code> system call which calls the command, then gets a callback
|
|
on completion, returning the complete result in one message, along with any errors.</p>
|
|
<p>Optionally can use <code>spawn</code> instead, which returns the output from stdout and stderr
|
|
as the command runs (usually one line at a time). On completion it then returns a return code
|
|
(on the 3rd output).</p>
|
|
<p>The optional append gets added to the command after <code>msg.payload</code> - so you can do
|
|
things like pipe the result to another command.</p>
|
|
<p>Parameters with spaces should be enclosed in quotes - <i>"This is a single parameter"</i></p>
|
|
<p>If stdout is binary a <i>buffer</i> is returned - otherwise returns a <i>string</i>.</p>
|
|
<p>The blue status icon will be visible while the node is active.</p>
|
|
<p>If running a Python app you may need to use the <code>-u</code> parameter to stop the output being buffered.</p>
