Changes

We will continue with using shell scripts to create a Software Information Report that manipulates output generated by the '''rpm''' command. The '''sed ''' and '''awk ''' commands are very useful tools in shell scripting to manipulate text. In this lab, we will be using ''sed '' to allow the user to select certqain certain portions from the rpm command (options -qi).
