| -c, --changes |
| | like verbose but report only when a change is made |
| --dereference |
| | affect the referent of each symbolic link (this is the default), rather than the symbolic link itself |
| -h, --no-dereference |
| | affect each symbolic link instead of any referenced file (useful only on systems that can change the ownership of a symlink) |
| --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 |

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.
