"chattr +i" is a blunt instrument; once set, the file or directory is completely immutable. 2. "chattr +a" doesn't allow appends; it denies everything except appends, so "chattr +a +i" is equivalent to just "chattr +i". 3. Modifying a directory isn't an "append", so "chattr +a" isn't useful here. If filesystem permissions cannot be used (e.g. because both the directory and its parent need to be writable by the user), you can still prevent the directory from being deleted by adding a file or subdirectory which the user cannot delete. One option is to add a subdirectory, owned by root, writable only by root, and containing at least one file. The user won't be able to delete the file as they don't have write permission on the subdirectory, and a non-empty directory cannot be deleted. Another option is to just add a file within the directory and use "chattr +i" on the file. -- Glynn Clements <glynn@xxxxxxxxxxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
