As user student, using your home directory as your present working directory pwd , untar the tarball. I am not a developer. In addition, every one of the documents I found assumes that the code needs to be compiled from sources as in a development environment.
That output shows all three links are properly created. So we simply copy those scripts and other files into the directories where they belong in the installed system. I always like to add a comment to this section that contains the exact syntax of the rpmbuild command required to create the package. This script is just a Bash shell script.

In the case of our package, it includes removing the link created by the %post script and restoring the saved original of the motd file.
