Hi I am trying to build an RPM that when installed/upgraded checks the present version of the package and depending on if the present version is a certain version or higher -> do something if lower -> do something else. i.e if present version is 1.0 or higher -> do something else if present present version is < 1.0 -> do something else. I have been told that I shouldn't use rpm command (i.e 'rpm-qa') in the inside the %pre or %prerun scriptlet as this can cause an RPM - how can I query the existing version in the rpmbuild/spec file?
Doing rpm queries from inside rpmbuild isn't any more recommended than install-time scriptlets, for similar reasons, and it wouldn't help anyway if you need to do such decisions at install-time.
What you can do from rpm scriptlets is try figuring out the version by other means, such as testing existence/naming of files of the other package, or executing some test-commands (lot of software has some means of outputting its version via --version or such cli switch)
