I may have done some copy/move operation involving large or many files. In bash I would like some hint that that operation is over. Is there anything I can do?

At first I thought, waiting on a pid should do the trick. Hence during one such operations, I ran `top` and found that `mount.ntfs` was taking most of the cpu. However, post this file operation (after the dialog automatically disappears) that process is still running.

Hence I ruled out that one. Any ideas on how I can know when my OS has dismissed that dialog?
