SETLABEL(1) User Commands SETLABEL(1)

NAME

setlabel - move files to zone with corresponding sensitivity label

SYNOPSIS

/usr/bin/setlabel newlabel filename...

DESCRIPTION

setlabel moves files into the zone whose label corresponds to newlabel.
The old file pathname is adjusted so that it is relative to the root
pathname of the new zone. If the old pathname for a file's parent
directory does not exist as a directory in the new zone, the file is not
moved. Once moved, the file might no longer be accessible in the current
zone.


Unless newlabel and filename have been specified, no labels are set.


Labels are defined by the security administrator at your site. The system
always displays labels in uppercase. Users can enter labels in any
combination of uppercase and lowercase. Incremental changes to labels are
supported.


Refer to setflabel(3TSOL) for a complete description of the conditions
that are required to satisfy this command, and the privileges that are
needed to execute this command.

EXIT STATUS

setlabel exits with one of the following values:

0
Successful completion.


1
Usage error.


2
Error in getting, setting or translating the label.

USAGE

On the command line, enclose the label in double quotes unless the label
is only one word. Without quotes, a second word or letter separated by a
space is interpreted as a second argument.

% 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

EXAMPLES

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
required.


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


example% setlabel -- -A somefile
