Hostapd - detect and execute command when a device is connected - error

Question

I am trying to execute a command on hostapd when there is a new connection established.

I used this example:

But when I start the script, on device connection, I receive an error:

pi@raspberrypi:~ $ sudo hostapd_cli -a '/onHostapdChange.sh'
Selected interface 'wlan0'

execv: No such file or directory

Could you help me please?

Make sure the interpreter at the beginning of your script exists. E.g. (#!/bin/sh) — user356765, Commented Sep 10, 2022 at 17:24
What are the parameters to the command? When I tried this hostapd_cli didn't exit. Do you have to re-do this ever time the machine restarts or does it somehow remember to run the script? — Richard Barraclough, Commented Jun 10, 2023 at 19:31

This sounds like, there is no such file at the specified path:

/onHostapdChange.sh

I would suggest you try to put the full path of the shell script inside the argument.
