Name

chcon — change file security context

Synopsis

chcon [OPTION...] CONTEXT FILE...

chcon [OPTION...] [ −u USER ] [ −r ROLE ] [ −l RANGE ] [ −t TYPE ] FILE...

chcon [OPTION...] −−reference=RFILE FILE...

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 _zsingle_quotesz_/_zsingle_quotesz_ specially (the default)
−−preserve−root: fail to operate recursively on _zsingle_quotesz_/_zsingle_quotesz_
−−reference=RFILE/: use RFILE_zsingle_quotesz_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
