I hesitated to ask this question, as I'm sure the answer is in the documentation somewhere...
I have an EXEC node which does an SCP to a remote raspberry pi 3. The copy is pretty big ~1G. When issuing scp from the command line, I get updates as to the progress of the copy xx% of xxxx.
I've tried setting the option in the exec node as SPAWN, and attached a function node to log to the console the output coming from the exec node. Nothing comes out until the copy is complete. I've also tried a STATUS node, referencing the exec node to no avail.
My goal is to display in my UI, the % copied, or "loading", or whatever, until it completes.
Any idea how to get updated status on exec commands with multiple outputs??
