udevBluetoothデバイスが接続されるたびにスクリプトを呼び出そうとします。これまで私がしたことは次のとおりです。
bluetooth.rulesにファイルを作成しました/etc/udev/rules.d。bluetooth.rulesそれ自体には1行だけが含まれています。
SUBSYSTEM=="bluetooth", RUN+="/path/to/myscript"
Bluetooth接続が行われるたびに実行したいです。そして終了;問題は、前者ではなく後者の場合にのみスクリプトが呼び出されることです。
接続が形成されたときの出力は次のようになりますudevadm monitor（実行後bluetoothctl connect <MAC address>）。
KERNEL[71481.889315] add /devices/pci0000:00/0000:00:14.0/usb3/3-11/3-11:1.0/bluetooth/hci0/hci0:256 (bluetooth)
UDEV [71481.903034] add /devices/pci0000:00/0000:00:14.0/usb3/3-11/3-11:1.0/bluetooth/hci0/hci0:256 (bluetooth)
KERNEL[71482.495175] add /devices/virtual/input/input45 (input)
KERNEL[71482.495248] add /devices/virtual/input/input45/event24 (input)
UDEV [71482.496423] add /devices/virtual/input/input45 (input)
UDEV [71482.591539] add /devices/virtual/input/input45/event24 (input)
これでデバイスの接続が失われました。
KERNEL[71553.849145] remove /devices/virtual/input/input45/event24 (input)
UDEV [71553.850872] remove /devices/virtual/input/input45/event24 (input)
KERNEL[71553.919022] remove /devices/virtual/input/input45 (input)
UDEV [71553.919624] remove /devices/virtual/input/input45 (input)
KERNEL[71556.168971] remove /devices/pci0000:00/0000:00:14.0/usb3/3-11/3-11:1.0/bluetooth/hci0/hci0:256 (bluetooth)
UDEV [71556.179602] remove /devices/pci0000:00/0000:00:14.0/usb3/3-11/3-11:1.0/bluetooth/hci0/hci0:256 (bluetooth)
実行後の結果は次のとおりですudevadm info --attribute-walk --path。
$ udevadm info --attribute-walk --path=/devices/pci0000:00/0000:00:14.0/usb3/3-11/3-11:1.0/bluetooth/hci0/hci0:256
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

呼び出されたスクリプトはそれほど複雑ではありません。これは、基本的にpkill別のプロセスにシグナルを送信する呼び出しを含む1行のコードです。
デバイスが接続されたときにスクリプトが呼び出されない理由を理解できません
私の直観によると、これはudevイベントの順序に関連していると言われています（udevadm monitorの出力によると、LIFOモデルに従うようです）。しかし、目標を超えた可能性があります。
私は何を見逃していますか？
