What changes needed in .spec file to rename installing software?

Question

I am trying to rebuild nano rpm package on CentOS 8 so after installing it I will be able to run nano using command newnano.
After some googling I came to the conclusion that I need to change .spec file and build package using command rpmbuild -ba nano.spec.
Here is what I've already tried:

1. Changing name in the beginning of .spec file, so it looked like that:
   Summary: A small text editor
Name: newnano
...
   But when I tried to build package there was error: Bad exit status from '/var/tmp/rpm-tmp.DSP7dc (%prep)
   As I understand after unzip tar archive its tried to cd newnano-2.9.8 but there is no such directory.
2. Adding alias in %install section:
   %install
cd build
%make install
rm -f %{buildroot}%{_infodir}/dir
alias newnano="nano"
...
   Building and installation was successful but alias was not created.
3. Using %package. I insert after %description and before %prep in original .spec this:
   %package -n newnano
Summary: test
%description -n newnano
test
   Also I add -n newnano to %files section. Building and installation was successful but new command was not added.

So how I have to change .spec file to achieve my goal?

Answer 1

There is a very simpe way to do it via rpmrebuild and .rpm nano package.

1. rpmrebuild -enp nano.rpm
2. In .spec file (it will open after previous comand) you should do these:
   • replace Name: nano with Name: newnano (optional, but recommended)
   • add mv /usr/bin/nano /usr/bin/newnano before the first exit 0 line. This section you can find before %changelog
3. Look carefully and remember the path of rebuilded .rpm that you will see after you close vim
4. Install rebuilded .rpm via rpm -i command
5. (Optional: maybe you will need to reboot)
