"dev/2" : {
None : [ "/bin/echo", "111", "*", "#!#", "222", "#!#", "333" ],
},
}
can you please help me

Answer 1

Add a line to the sys/file, right after info, that says the following:
'launch' : [ '/usr/bin/python', 'simple_stream.py' ],
This way, when you send the payload 'launch' (without quotes) to the topic sys/file, it will execute the desired python script. Please adjust with the path of your python executable (in linux: 'which python' will tell you the path).
Hope this helps.
