To downgrade date, you first move the file to its target directory, then relabel it. For an explanation, see Multilevel Datasets for Relabeling Files in Trusted Extensions Configuration and Administration .
Before You Begin
You must be authorized to downgrade files. The administrator has mounted a multilevel dataset in at least one of the labeled zones, and has used a standard name, such as /multi, for all mounts of the dataset that you can access, and has permitted relabeling in that zone.
Therefore, your administrator must have completed the following tasks:
How to Create and Share a Multilevel Dataset in Trusted Extensions Configuration and Administration
You must be logged in to a multilevel session.
For example, create an internal workspace.
For details, see How to Add a Workspace at Your Minimum Label.
% pfbash $
For details, see How to Determine the Label of a File.
$ mv /multi/internal-directory/file /multi/public-directory
$ cd /multi/public-directory $ setlabel public file
$ getlabel /multi/public-directory/file /multi/public-directory/file: PUBLIC
You can edit the file at the PUBLIC label.
In this example, an authorized user relabels a directory.
First, the user moves or removes all files from the directory.
$ getlabel /multi/conf /multi/conf: CONFIDENTIAL : NEED TO KNOW $ mv /multi/conf/* /multi/confNTK/temp
Then, the user sets the label of the directory and verifies the new label.
$ setlabel "Confidential : Internal Use Only" /multi/conf getlabel /multi/conf /multi/conf: "CONFIDENTIAL : INTERNAL USE ONLY"
