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 '/' 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
