description

Change the security context of each FILE to CONTEXT. With --reference, change the security context of each FILE to that of RFILE.
--dereference

affect the referent of each symbolic link (this is the default), rather than the symbolic link itself

-h, --no-dereference

affect symbolic links instead of any referenced file

-u, --user=USER

set user USER in the target security context

-r, --role=ROLE

set role ROLE in the target security context

-t, --type=TYPE

set type TYPE in the target security context

-l, --range=RANGE

set range RANGE in the target security context

--reference=RFILE

use RFILE’s security context rather than specifying a CONTEXT value

-R, --recursive

operate on files and directories recursively

-v, --verbose

output a diagnostic for every file processed

The following options modify how a hierarchy is traversed when the -R option is also specified. If more than one is specified, only the final one takes effect.

-H

if a command line argument is a symbolic link to a directory, traverse it

-L

traverse every symbolic link to a directory encountered

-P

do not traverse any symbolic links (default)

--help

display this help and exit

--version

output version information and exit
