- <p>Calls out to a system command.<br/></p>
- <p>Provides 3 outputs... stdout, stderr, and return code.</p>
- <p>By default uses exec() which calls the command, blocks while waiting for completion, and then returns the complete result in one go, along with any errors.</p>
- <p>Optionally can use spawn() instead, which returns output from stdout and stderr as the command runs (ie one line at a time). On completion it then returns a return code (on the 3rd output).</p>
- <p>Spawn only expect one command word, with all extra parameters to be comma separated and passed as the append.</p>
- <p>The optional append gets added to the command after the <b>msg.payload</b> - so you can do things like pipe the result to another command.</p>
