chown [OPTION]... --reference=RFILE FILE...
- -c, --changes
- like verbose but report only when a change is made
- -f, --silent, --quiet
- suppress most error messages
- -v, --verbose
- output a diagnostic for every file processed
- 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 (useful only on systems that can change the ownership of a symlink)
- 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
- do not treat '/' specially (the default)
- fail to operate recursively on '/'
- use RFILE's owner and group rather than specifying OWNER:GROUP values
- -R, --recursive
- operate on files and directories recursively
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.
- if a command line argument is a symbolic link to a directory, traverse it
- traverse every symbolic link to a directory encountered
- do not traverse any symbolic links (default)
- display this help and exit
- output version information and exit
Owner is unchanged if missing. Group is unchanged if missing, but changed to login group if implied by a ':' following a symbolic OWNER. OWNER and GROUP may be numeric as well as symbolic.
- chown root /u
- Change the owner of /u to "root".
- chown root:staff /u
- Likewise, but also change its group to "staff".
- chown -hR root /u
- Change the owner of /u and subfiles to "root".
