rpmbuild:tldr:54671

The command "rpmbuild -ba ${path-to-spec_file}" is used to build a binary RPM package from a .spec file.

Here is the breakdown of the command:

• "rpmbuild" is the command-line tool used to build RPM packages. It is available on RPM-based Linux distributions like Red Hat, CentOS, Fedora, etc.
• "-ba" is a command-line option for rpmbuild. It stands for "build all" and instructs rpmbuild to build both the source and binary RPM packages.
• "${path-to-spec_file}" is a placeholder indicating the path to the .spec file that describes the package. The .spec file contains information about the package, its dependencies, build instructions, etc. You need to provide the actual path to the .spec file you want to build.

For example, if your .spec file is located at /home/user/mypackage.spec, the command will be:

rpmbuild -ba /home/user/mypackage.spec

After executing this command, rpmbuild will follow the instructions in the .spec file, compile the source code (if necessary), create the binary package, and place it in the appropriate directory according to your distribution's conventions (e.g., /usr/src/rpm/RPMS/ for CentOS).
