However, when the filesystem is mounted with >versioning enabled, file versions created using undelete -v will not be >visible." The only way that can be done is to "move" the files somewhere else. Several have done such a "rm" command, for example. So that instead of removing the file outright, it is moved into another directory where it can later be recovered if desired. However, that is not really "removing" the file. Once a file is truly removed, it is _gone_ forever. It sounds as if they also did a modification on the ls command so that it can show such files, or else they modified the entire filesystem to support files with some special character which means "present but it has been deleted." That is not a "unix" facility however. Thank goodness...
