ROLE] [-l RANGE] [-t TYPE] FILE...
chcon [OPTION]... --reference=RFILE

DESCRIPTION
Change the SELinux security context of each FILE to CONTEXT. With --reference, change the security context of each FILE to that of RFILE.
Mandatory arguments to long options are mandatory for short options too.
- --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
- --no-preserve-root
-
do not treat '/' specially (the default)
- --preserve-root
-
fail to operate recursively on '/'
- --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
