How can I automatically check if a file has changed?

I have written some little code but it seems not to work as I want to.

#!/bin/bash

while true; do
        xdg-open test.mp4
        inotifywait -e modify test.mp4

done

Simply I want to open a .mp4 file but it can be replaced anytime and if it replaced one day the script should be recognize it and restart the .mp4 file again.

I hope someone can help me.

Use inotifywait instead of inotifywatch:

while true; do
    inotifywait -e modify file.mp4
    xdg-open file.mp4
done 2>&1 > /dev/null & disown ; exit

Basically it xdg-open file.mp4, sleeps until modify, reopens it...
