Echo statements from a bash script

General
1

I have a bash script which is run by using an exec node, on a timer.
The script also generates echo statements, such as echo "script started... but they do not appear in any of the 3 exec node outputs.
I really need the outputs because they would trigger other actions in a node-RED flow.

What am I doing wrong?

Are you using spawn mode?

3

I've tried both, but no outputs except { code: 0 } when the script finishes.

4

Are you redirecting stdout in the script?:

5

I've tried echo "Starting daily backup..." >&1 which didn't work
is that the correct way?

Julian's script redirects the stdout at the beginning. Try commenting out the exec1 to allow the echo to be sent to stdout.

As long as your exec node is set to output while the command is running - spawn mode, you should get a message generated by each echo command in your script.

>&1 is definitely not needed.

Can you export the timer, exec and debug nodes to share?
If the script is not confidential, share that too.

Thanks @E1cid that was the reason!!
I've commented it out, and now I get the echo statements that I need :grinning:
