If you take a look at the cron script that generates /var/log/rpmpkgs, you
can see it is just a rpm query with a specified format.  Adjusting this
query to give you just the name would give you:

rpm -qa --qf '%{name}'

You might also be interested in piping it through "sort", as the cron
script does.
