  i suspect there are yum alternatives for some of these but here's
some stuff i like:

  $ rpm -qa			# list all installed packages
  $ rpm -qR <pkgname>		# list dependencies of package
  $ rpm -ql <pkgname>		# display list of files in package
  $ rpm -qf <filename>		# what package is <filename> from?

and many others.
