I made a script to invoke `inotifywait`.
It works fine, but I sometimes want to stop it.

How do I stop the last `inotifywait` instance?

I cannot understand how to use `inotify_rm_watch` which I understand is used to close it.

```
7341 ?        S      0:00 inotifywait -m /home/andy/Downloads/ --format %w

```
