I am working on Raspian OS (Linux) for Raspberry Pi 3. I am trying to do a simple task say when I connect any USB to the port it should copy the data from a particular location to the USB and clear the file in that location, Here is my script(testscript.sh),
#gpio 1 and 0 are for led on/off while copying gpio -g mode 17 out gpio -g write 17 1 sleep 10 sudo cp -f /home/pi/NewLog.log /media/usb/NewLog-$(date -u'+%Y%m%d%H%M').log if [ $? -eq 0 ]; then echo -n > /home/pi/NewLog.log fi gpio -g write 17 0 echo "content copied to USB"
I have created an UDEV rule in /etc/udev/rules.d
KERNEL=="sd*", SUBSYSTEMS=="usb", ACTION=="add",RUN+="/home/pi/testscript.sh"
I have also installed usbmount, so that the USB automounts in /media/usb folder I also found usbmount.rules in /lib/udev/rules.d
Now everytime I plug the USB it copies an Empty file to the USB, and after unplugging the USB the actual copied file is in location /media/usb...
I am guessing that the rule in /etc/udev/rules.d/myrule executes before the /lib/udev/rules.d/usbmount, maybe thats is why it copies the data to /media/usb before my USB mounts ! Any help will be much appreciated
