You can view the installation and uninstallation scripts inside an RPM (Red Hat Package Manager) file by using the rpm command with the --scripts option.
For example, to view the scripts inside an RPM file named package.rpm, you can use the following command:
rpm -qp --scripts package.rpm
This will display the installation and uninstallation scripts contained in the RPM file. The installation script is typically named preinstall or install, and the uninstallation script is typically named postuninstall or uninstall.
You can also use the --queryformat option to specify the output format of the script names and contents. For example, to display the contents of the installation script only, you can use the following command:
rpm -qp --scripts --queryformat '%{prein}\n' package.rpm
This will display the contents of the preinstall script contained in the RPM file.
You can use the --queryformat option to display the contents of the other scripts as well. For example, to display the contents of the uninstallation script, you can use the %{postun} format specifier.
By using the rpm command with the --scripts and --queryformat options, you can view the installation and uninstallation scripts contained in an RPM file and customize the output format to suit your needs.
