This post if applicable to all the distro\’s which are based on rpm.
If you look at the number of rpms installed on your system, you will see it somewhere around 500-2000. Noe thats a pretty huge number. So sometimes I keep wondering what are these rpms for. Heres a command that can help you figure out what these rpms are for:
rpm -qa –info
And if you want to find info on all the files and put it in a file too:
rpm -qa –info |tee <filename>
