Is it possible to shorten the command?

Is it possible to write Author Name only once?

exiftool -progress: -progress -overwrite_original -r -artist="Author Name" -copyright="Author Name" -by-line="Author Name" -copyrightnotice="Author Name" -creator="Author Name" -rights="Author Name" *.cr2

Yes.  You can create a user-defined Shortcut to write all of these tags at once.  See the MyShortcut definition in the sample config file for an example.

Am I doing right?

.ExifTool_config:
%Image::ExifTool::UserDefined::Shortcuts = (
    copyrights => ['artist','by-line','copyright', 'copyrightnotice', 'creator', 'rights'],
);
1;

Console:
exiftool -progress: -progress -overwrite_original -r -copyrights="Author Name" *.cr2

[Phil Harvey]

You tell me:  Did it work?

If yes, then the answer is yes.

If no, then the .ExifTool_config file probably isn't in the correct location.
