8.6 Directory and File Attributes for NSS Volumes or NetWare Traditional Volumes
Directory and file attributes assign properties to individual directories or files. Some attributes are meaningful only when applied at the file level, but some apply to both the directory and the file levels.
File attributes apply universally to all users. For example, a file that has a read-only attribute is read-only for all users. The file attribute settings are like an on/off switch. Attributes can be set by any trustee with the Modify right to the directory or file, and attributes stay set until they are changed. Attributes do not change when you log out or when you down a file server.
IMPORTANT:Be careful when assigning a directory and file attribute. The attribute applies to all users.
For example, if a trustee with the Modify right enables the Delete Inhibit attribute for a file, no one, including the owner of the file or the network administrator, can delete the file. However, any trustee with the Modify right can disable the Delete Inhibit attribute to allow the file’s deletion.
Table 8-1 describes directory and file attributes and whether they are apply to directories, files, or both.
