In Node-Red, how to execute a script with arguments but not wait for completion?

I want to message a telegram bot a code which is used as an argument for a python script. Problem is, the script does a sleep function until the day/time it needs to run.



Is it possible to run a script without waiting for completion; sending it to the background so that node-red can execute another instance of the script when it gets a new code from telegram?



I tried the daemon node but it doesn't have a feature to add arguments from the payload, unless I am doing it wrong.

          The 'Exec' node can be configured to output messages while the command is still running - known as 'spawn mode'. Just take note of the tip in the Exec node's sidebar help:

          how to define a CAPL function taking a sysvar argument

          Image
          up vote 0 down vote favorite In Vector CANoe, is it possible to define a function that takes a system variable argument like the system function TestWaitForSignalMatch() ? For my use case it is not sufficient to supply the current value of the system variable because I want to pass the system variable to TestWaitForSignalMatch() or similar system functions. The CANoe help seems to show examples: long TestWaitForSignalMatch (Signal aSignal, float aCompareValue, dword aTimeout); // form 1 long TestWaitForSignalMatch (sysvar aSysVar, float aCompareValue, dword aTimeout); // form 3 I tried like this void foo(sysvar aSysvar) {} ^ or this void foo(sysvar *aSysvar) {} ^ but I get a parse error at the marked position of the sysvar keyword in both cases. I successfully created functions that take a...
