编写了 udev 规则来运行脚本，但什么也没发生

这是我的 81-arduino.rules 文件：

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

因此，当我插入 Arduino 脚本时应该启动，但什么也没有发生。

$ 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

我的脚本：

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

需要测试以下几件事：

  • 你的脚本是否在运行，但出现了错误？人们会不小心做出各种环境假设，所以只要确保有什么问题防弹在开始的脚本中，例如：

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

    如果事实证明它正在运行，那么您可以修复它。使用完整路径。切勿使用类似 的替换~。脚本将从非常原始的上下文中运行。

  • 你的 UDEV 规则正确吗？插入时查看日志：

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

    检查您的供应商、产品和序列号。

  • 尝试稍微宽松一些的搜索，忽略 KERNEL 和 SERIAL：

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