At the moment I have an application that has a playlist, but if the user moves the file I lose the reference to the file. The way I am doing it is simply keeping reference to the file path. If there is a way to keep track of the file when it is moved on disk, then I would be interested in knowing what the trick is. This email sent to site_archiver(a)lists.apple.com

If I recall correctly, vi saves a file by writing out a new copy, deleting the old one, and then renaming the new copy to the old name. This way the file is always intact, even if something goes wrong during the "save" operation. This is fairly common behavior for text editors on UNIX platforms.

Thus you really have a brand new file with a brand new creation date. Hello, Actually I used the vi editor to modify the file. When I use touch command or cat >> example the creation time does not change. But why should this happen? This behaviour is not seen with Windows. Looks fine till here. Now if I modify the contents of the file "example". How are you modifying it? If the program you use actually writes a new file, then this is the expected behavior: It seems the bash builtin echo modifies the file whereas vim (probably) performs the safer operation of writing a temporary file and then using rename(2) to replace the file.
