Estou tentando permitir que meu Raspberry Pi (executando Debian Jessie) envie uma notificação para Pushbullet quando por algum motivo meu HDD estiver desconectado, usando regras do udev. Agora consegui fazer isso funcionar. O problema, entretanto, é que o script é executado 14 vezes em vez de apenas uma vez e é executado em ações de desconexão E conexão, o que não é minha intenção.
Eu tentei várias configurações diferentes do arquivo de regras, como:
ACTION==”remove”,
KERNEL==”sda1”,
SUBSYSTEM==”block”,
KERNELS==”1-1.2”,
SUBSYSTEMS==”usb”,
ATTRS{idProduct}==”10a2”,
ATTRS{idVendor}==”1058”,
ATTRS{manufacturer}=="Western Digital",
RUN+="/home/pi/HDD_removed.sh"
e
ACTION=="remove",
ENV{ID_MODEL}=="Elements_10A2",
RUN+="/home/pi/HDD_removed.sh"
e outros, mas nada funciona corretamente.
Para ajudar, imprimi as saídas do udevadm info e do udevadm monitor abaixo (desculpe pelos tamanhos grandes ..):
$ informações do udevadm -a -p $(informações do udevadm -q caminho -n /dev/sda1)

Graças asujeirapara encontrar a solução:
Na verdade, as regras devem estar em uma única linha. Isso corrige as chamadas repetidas de script (se uma variável exclusiva for usada) e agora o script só é chamado quando o dispositivo é desconectado. Para mim, a seguinte configuração funcionou:
ACTION=="remove", ENV{ID_FS_UUID}=="21741F4F6C4915E1", RUN+="/home/pi/HDD_removed.sh"

Como outros já identificaram, cada linha em seus trechos é uma regra separada, ou não fazendo nada (linhas com only ==) ou executando um comando em cada evento do udev (linhas com only =ou +=). Você precisa colocar toda a regra em uma única linha lógica.
Você pode dividir linhas nas regras do udev, mas será necessário colocar uma barra invertida no final de uma linha se a regra continuar na próxima linha. Em outras palavras, uma linha lógica pode conter a sequência de dois caracteres barra invertida-nova linha, que é ignorada.
ACTION=="remove", \
ENV{ID_MODEL}=="Elements_10A2", \
RUN+="/home/pi/HDD_removed.sh"
