I have an RPM package for my application and the path of the installation is /company/application/version.
I am finding this difficult as it is a unix platform and there is no registry concept.
I need few things to be clarified:
- How can i check the previous installed version number?
Every time I install my different version application all gets installed (i.e 2.5 and 2.6 both are considered as 2 different softwares because of the installation directory structure.)
- How can I stop the newer version when old is already installed?
