I believe what he meant was you can actually see the name of RPM in the directory. To view files in console the command is ls (LS lowercase) and there are other options for it as well. I prefer this when browsing large directories:
That's all lowercase LS -L|LESS, notice the pipe | It's the key above the enter key on my US keyboard. Then to browse you can use the up and down arrows or Enter or spacebar.
From there, you can find the actual RPM you want to install, and not have to use wildcard character(s) *
Then type it out:
rpm -i kernel-source-2.4.18-14.i386.rpm
And don't forget tab autocompletion. Press TAB after typing kernel-source and see if it autocompletes.
