setlabel - move files to zone with corresponding sensitivity label


/usr/bin/setlabel newlabel filename...

% setlabel SECRET somefile
% setlabel "TOP SECRET" somefile

Use any combination of upper and lowercase letters. You can separate
items in a label with blanks, tabs, commas or slashes (/). Do not use any
other punctuation.

% setlabel "ts a b" somefile
% setlabel "ts,a,b" somefile
% setlabel "ts/a b" somefile
% setlabel " TOP SECRET A B " somefile


Example 1: Set a Label.

To set somefile's label to SECRET A:

example% setlabel "Secret a" somefile

Example 2: Turn On a Compartment.

Plus and minus signs can be used to modify an existing label. A plus sign
turns on the specified compartment for somefile's label.

example% setlabel +b somefile

Example 3: Turn Off a Compartment.

A minus sign turns off the compartments that are associated with a
classification. To turn off compartment A in somefile's label:

example% setlabel -A somefile

If an incremental change is being made to an existing label and the first
character of the label is a hyphen (-), a preceding double-hyphen (--) is

To turn off compartment -A in somefile's label:

example% setlabel -- -A somefile
