inotifywait

Download inotifywait from here and install it.

#!/bin/bash
inotifywait -m /public/software/anaconda/requirements.txt --timefmt '%d/%m/%y %H:%M' --format '%T %w %f' -e modify -e move -e delete_self | while read date time action dir file; do
    FILECHANGE=${dir}${file}
    echo "At ${time} on ${date}, file $FILECHANGE was touched via '$action'" | mailx -s "requirements" -a /public/software/anaconda/requirements.txt [email protected]
done

Explanation:

-m|--monitor  	Keep listening for events forever.  Without
              	this option, inotifywait will exit after one
              	event is received.
-e|--event <event1> [ -e|--event <event2> ... ]
	Listen for specific event(s).  If omitted, all events are 
	listened for.
