Answer 1

Try with rpmbuild command. I dont think rpm has an "-ba" option.

Answer 2

You did not specify the version of RedHat or CentOS linux that you're using. rpm -ba option was removed from rpm many years ago. So, presuming you're using RHEL 5.x or CentOS 5.x or later, you need to use rpmbuild command to build your RPMs

However: It appears you're following some kind of a book or manual in your rpm study. This source of information is very outdated if it suggests using rpm -ba to build RPMs. I think you'd better find a more recent book or manual, since RPM has evolved considerably in the recent years. You can start with rpmbuild man page or see the list of available documentation on RPM web site.
