Fdisk and grep command not working in udev trigger
Hi Guys,

Can someone take a look at my scripts what missing, plugin usb drive the script is running can log all my echo but cannot execute command. Is there any configuration in linux or to my scripts need to add?.

What i want to achieve is every time I plugin the usbdisk automatic mount to /media/usb/test

Code:
cat /etc/udev/rules.d/100-mount-usb.rules

ACTION=="add", SUBSYSTEMS=="usb", ATTR{idVendor}=="8564", ATTR{idProduct}=="1000", RUN+="/bin/bash -c /usr/local/bin/test.sh"

Code:
cat /usr/local/bin/test.sh

#!/bin/bash

LOG_FILE=/opt/weekly_backup.log

DEVNAME=$(fdisk -l |grep FAT16 |awk '{print $1}')

echo "New usb device detected at $DEVNAME" >> $LOG_FILE

echo "mount $DEVNAME /media/usb/test" >> $LOG_FILE

mount $DEVNAME /media/usb/test &>> $LOG_FILE

Reload all rules in udev:
Code:
udevadm control --reload-rules

Trigger all udev rules:
Code:
udevadm trigger

Here the log ouput:
Code:
cat /opt/weekly_backup.log

New usb device detected at
mount  /media/usb/test
mount: can't find /media/usb/test in /etc/fstab or /etc/mtab

fpga_load

FPGA_LOAD(8)															      FPGA_LOAD(8)

NAME

       fpga_load - Xorcom Astribank (xpp) firmware tool

SYNOPSIS

       fpga_load [-g] [-r] [-v] -D {/proc/bus/usb|/dev/bus/usb}/BUS/DEV

       fpga_load [-g] [-v] -D {/proc/bus/usb|/dev/bus/usb}/BUS/DEV -I firmware.hex [-b dump.bin] [-i]

       fpga_load -h

DESCRIPTION

       fpga_load loads the FPGA firmware to the Xorcom Astribank device.  The syntax resembles that of fxload(8).

OPTIONS

       -b dump.bin
	      Before writing firmware, bump the processed binary file to dump.bin.

       -D DEVICE
	      Required.  The  device  to  read	from/write  to. On modern UDEV-based system this is usually /dev/bus/usb/bus_num/device_num, where
	      bus_num and device_num are the first two numbers in the output of lsusb(8).   On	older  systems	that  use  usbfs,  it  is  usually
	      /proc/bus/usb/bus_num/device_num.

       -r
	      Reset the Astribank and renumerate its USB connection to power on product ID.

       -g
	      Dump all eeprom data to standard output.

       -I fireware_file
	      The firmware file to write to the device.

       -i
	      Show information about the firmware file (valid only with -I option).  Example:

		   ./FPGA_1151.hex: Version=3297 Checksum=58270

	      In particular, the calculated checksum should match the output of sum(1) on the binary firmware file generated by the -b option.

       -v
	      Increase verbosity. May be used multiple times.

       -h
	      Displays usage message.
