Custom M codes don't work on Rasberry Pi 5 + Messa 7i95

Hello everyone! This is my first post on the forum. I have a problem with setting up custom M codes on Raspberry + 7i95. I need additional outputs to control the equipment. Just turn on and off some outputs on the 7i95.
In principle, nothing complicated, but when executing custom M code, linuxcnc does not display error messages and the pin states on the 7i95 outputs do not change.
There are no changes in halshow either.

I use this image www.linuxcnc.org/iso/rpi-5-debian-bookwo...25-01-27-0140.img.xz

Here is one of the commands (M101)
#!/bin/bash
halcmd setp hm2_7i95.0.ssr.00.out-01 True
exit 0

Even if you intentionally make a mistake in the M command file, linuxcnc still does not give any error messages.
Has anyone encountered this problem on Rasberry Pi?

Does your script have execute permissions?

Yes, of course. Without permission, Linuxcnc gives an error message.

Does the command you are trying to use in the M-code, work in a terminal from the command line?

Do you get any error messages in the terminal when you try to run the M-code if you start Linuxcnc from the command line?

Does the script work if run from the command line?

 That is, does:

./M101

work?
 

Tried it two ways, still doesn't work. In the first case it gives an error.

pi@raspberrypi5:~/linuxcnc/nc_files $ ./M101
bash: ./M101: cannot execute: required file not found
pi@raspberrypi5:~/linuxcnc/nc_files $ bash M101
