→Investigation 7: How do you install and remove software with yum?
# Issue an RPM query to verify that BackupPC is no longer installed.
# Install <code>nled</code> using '''yum'''.
# Issue this command: <code>yum info cups</code>
#* Based on the result, do you think that cups is a useful package for your system? If not, try removing it.
# Find at least 4 other packages that you're not using on your system, and remove them. Be careful to ensure that removing those packages does not also remove other software that you do need.
