18. chown [OPTION]... [OWNER][:[GROUP]] FILE...
-c, --changes like verbose but report only when a change is made
--dereference affect the referent of each symbolic link, rather than the symlink
-h, --no-dereference affect each symbolic link instead of any referenced file
--from=CURRENT_OWNER:CURRENT_GROUP
change the owner and/or group of each file only if its current owner and/or group match those
specified here. Either may be omitted, in which case a match is not required for the omitted
attribute.
--no-preserve-root do not treat '/' specially (the default)
--preserve-root fail to operate recursively on '/'
-f, --silent, --quiet suppress most error messages
--reference=RFILE use RFILE's owner and group rather than specifying
OWNER:GROUP values
-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
