Escreveu a regra do udev para executar o script, mas nada acontece

Question

Aqui está o meu arquivo 81-arduino.rules:

KERNEL=="ttyACM*", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0043",  ATTRS{serial}=="754393133373519132C0", RUN+="/home/z37/screenrun.sh"

Então, quando eu plug-in script Arduino deve começar, mas nada acontece.

$ sudo unbuffer udevadm monitor --environment

custom logging function 0x7f5296f7e250 registered
selinux=0
runtime dir '/run/udev'
calling: monitor
monitor will print the received events for:
UDEV - the event which udev sends out after rule processing
KERNEL - the kernel uevent

Meu script:

#!/bin/bash gnome-terminal -x sh -c "sudo screen /dev/ttyACM* 115200; bash"

Algumas coisas para testar:

• O seu script está em execução, mas está apenas fazendo algo errado? As pessoas acidentalmente fazem todo tipo de pressupostos de ambiente, então apenas certifique-se de que há algo à prova de balas no script no início, por exemplo:

  echo running >> /home/z37/screenrun.log
  

  Se estiver funcionando, é algo que você pode consertar. Use caminhos completos. Nunca use substituições como ~ . O script será executado a partir de um contexto muito simples.

• A sua regra UDEV está correta? Assista ao log enquanto você o conecta:

  sudo apt-get install expect-dev
  sudo unbuffer udevadm monitor --environment
  

  Verifique seu fornecedor, produto e publicações em série.

• Tente uma pesquisa um pouco mais solta, ignorando KERNEL e SERIAL:

  SUBSYSTEM=="usb", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0043", RUN+="/home/z37/screenrun.sh
