Probably a simple for loop would sort them out for you.  Then you
could remove those that are dubs (or find other problems, but still
get installable ones installed)

I haven't done this but I think the rpm --test command may be your
friend here.  I only tried agains a very small sample.

Probably work without the --test too, but testing  would be a little safer.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  #!/bin/bash
  RPM_DIR=/some/rpm_dir
  ## cd to the scene of the crime
  cd $RPM_DIR

  for ii in `ls *rpm`  ## get a working list of all the rpms in there
  do
    ## test and record (including stderr)  each file
    rpm -Uvh --test $ii > test_results 2>&1
    ## if test shows exit status of 0 then run the install command.
    if [ "$? = 0 ]; then
       ## record installationn 
       rpm -Uvh $ii 2>&1|tee -a installed_results 
    fi
  done
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

That should leave you with the installable ones installed,
uninstallable ones will be recorded in test_results
In case there were other reasons besides being installed already.

Install output will be recorded in installed_results but also piped
to screen so you see what is happening.
