yes use a Mcode for your scripts to be started like M130

#!/usr/bin/python
#my python
myPython.py
exit 0

you might set the io level bevore
mypyprogram.py &
or
halcmd setp iocontrol.0.lube_level 1

Ok, thank you!
Can I insert python script into Mcode?
For example:

#!/usr/bin/python

import os
import sys

txtfile= open('\home\user\Documents\test.txt', 'w')
txtfile.write("TEST SCRIPT")
txtfile.close()

exit 0

Is there any other way to run automatically a python script on a program start without use a Mcode?
Thank you!

You can run a HAL file on exit, automatically:
SHUTDOWN = .... linuxcnc.org/docs/2.7/html/config/ini-config.html#_hal_section

The HAL file could[1] "loadusr" a userspace HAL component that makes no pins, asserts "hal.ready" and then quits itself:
linuxcnc.org/docs/2.7/html/hal/halmodule.html

[1] Probably. I have never tried this.
