chcon --help (return code: 0)
Usage: chcon [OPTION]... CONTEXT FILE...
or: chcon [OPTION]... [-u USER] [-r ROLE] [-l RANGE] [-t TYPE] FILE...
or: chcon [OPTION]... --reference=RFILE FILE...
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
