Shell Script - Compare packages. rpm

[Tiago Dias <tux.tiago@xxxxxxxxx>]

Hi,

         I need a script which makes the package compação rpm's through two text files ... 

         Since a file is the output of the command rpm-qa > pkg.out 

         And the second file is a list of several packages rpm's, multiple versions and architectures. 

         My idea is to compare a package x file pkg.out with several packages y of the file update.out and know whether a package and has
a larger version of the package x installed and with that I return I have a package to be updated. 

        Does anyone can help me do this comparison? 

        OBS.: The servers do not have access to internet.

        Here's an example of the packages described in the files:
