Which filesystems does it work on?Looks like you are looking for extended attributes: http://en.wikipedia.org/wiki/Extended_attributes But I don't think you can make them "disappear" by modifying a file. Inotify might be a solution for that problem: http://en.wikipedia.org/wiki/Inotify Alternatively you could check the file modification times as stored by default on every FS. You could use "find" for that or "ls --full-time".
