The rpm command provides three main operations for upgrading and installing packages: Upgrade An upgrade operation means installing a new version of a package and removing all previous versions of the same package. If you have not installed a package previously, the upgrade operation will install the package. Freshen A freshen operation means to install a new version of a package only if you have already installed another version of the package. Install An install operation installs a package for the first time. It also, through special command-line parameters, allows you to install multiple versions of a package, usually not what we want. So, in the vast majority of cases, you want to run the upgrade operation for all package installations.
Should normally install packages with rpm -U, not rpm -i. One of the main reasons is that rpm -i allows you to install multiple instances of the same (identical) package.
- Is this the standard conclusion or
- should I stop installing the second instance of the package along with the first instance by writing any wrapper script or by adding code in spec file section.
If 2 point is the answer how can achieve this. Please guide me about this confusion.
