The Redhat administration system are using rpm as a packagemanager.

to see which packages you have installed execute

rpm -qa

to see which files that package are containing execute

rpm -ql <packagename>

To install and unitall downloaded packages use

 rpm -ivh to install and rpm -e to unistall rpm -Fvh upgrades only already installed packages

Does that answer you questions??

3)md5sum packagename.rpm
