-**NOTE:**
-  * **-m, --monitor**:  Instead of exiting after receiving a single  event, execute indefinitely.  The default behavior is to exit after the first event occurs.
-  * **-r, --recursive**:  Watch all sub-directories of any directories passed as arguments.   Watches will be set up recursively to an unlimited depth.
-    * Symbolic  links  are  not  traversed.  Newly created sub-directories will also be watched.
