Without	       	this option, inotifywait will exit after one	       	event is received.	-d|--daemon  	Same as --monitor, except run in the background	       	logging events to a file specified by --outfile.

If <seconds> is 0, inotifywait will never time out.	-e|--event <event1> [ -e|--event <event2> ... ]		Listen for specific event(s). If omitted, all events are 		listened for.    Exit status:	0 - An event you asked to watch for was received.	1 - An event you did not ask to watch for was received	2 - The --timeout option was given and no events occurred	   in the specified interval of time.Events:	access		file or directory contents were read	modify		file or directory contents were written	attrib		file or directory attributes changed    close_write	file or directory closed, after being opened in writable mode	close_nowrite	file or directory closed, after being opened in read-only mode    close		file or directory closed, regardless of read/write mode	open		file or directory opened	moved_to	file or directory moved to watched directory	moved_from	file or directory moved from watched directory    move		file or directory moved to or from watched directory	create		file or directory created within watched directory	delete		file or directory deleted within watched directory	delete_self	file or directory was deleted	unmount		file system containing file or directory unmounted
