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? 

Looks like you want to see what the update packages are without doing the updates, and without an internet connection. About 5 years ago I would have suggest running 'rpm --freshen --test packagename-from-update.out'. Today, I'd suggest saving even more time and just a local instance of mrepo. Configure your yum repos in /etc/yum.repos.d/ to point to the repository, and install the yum-updatesd package to find out what the new packages are... Why reinvent the wheel? ;)
