Root owns the file and it is in the group "root". You have been warned. You will have to deal with it. It belongs to bob in particular and it is one 1 file.

So, a newly created file will have rwx permission for the owner, and rx permission for group and others.execute = access files in the directory; chmod never changes the permissions of symbolic links. This is not a problem since the permissions of symbolic links are never used. However, for each symbolic link listed on the command line, chmod changes the permissions of the pointed-to file.
