# How to extend this script
# Run:
# find /home/abhisek -name '*' -exec file {} \;
# Replace the path /home/abhisek with desired path
# Note the file format at the end of each line
# Then replace grep -o -P '^.+: \w+ image' with the file format you want to filter
# Replicate the for loop to extend the script

# add a new rule in there like this:
# ACTION=="add", ATTRS{idVendor}=="0a81", ATTRS{idProduct}=="0101", RUN+="/home/your_username/bin/myscript.sh"
