File Security

File security operations that can be performed on a given file using ctadmn are as follows:

  • Change the File’s Password.
  • Change the File’s Permission Mask, controlling file operation permissions for three classes of users: World, Group, and File Owner.
  • Change the File’s Group.
  • Change the File’s Owner.

Note: Applications can be designed so separate data files and/or index files can be joined into a “superfile,” which is a single physical file from the point of view of the operating system. Separate “logical” files within a superfile are called superfile member files. From the point of view of the Administrator, superfiles, member files, and separate data or index files are all treated the same way.
