Linux "chcon" Command Line Options and Examples

change file security context

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.

Usage:

chcon [OPTION]... CONTEXT FILE... chcon [OPTION]... [-u USER] [-r ROLE] [-l RANGE] [-t TYPE] FILE... chcon [OPTION]... --reference=RFILE FILE...

Command Line Options:

--dereference

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


                            chcon --dereference ...

-h

affect symbolic links instead of any referenced file


                            chcon -h ...

-u

set user USER in the target security context


                            chcon -u ...

-r

set role ROLE in the target security context


                            chcon -r ...

-t

set type TYPE in the target security context


                            chcon -t ...

-l

set range RANGE in the target security context


                            chcon -l ...

--no-preserve-root

do not treat '/' specially (the default)


                            chcon --no-preserve-root ...

--preserve-root

fail to operate recursively on '/'


                            chcon --preserve-root ...

--reference

-R

                            chcon -R ...

                            chcon -v ...

-H

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


                            chcon -H ...

-L

traverse every symbolic link to a directory encountered


                            chcon -L ...
