Objectives

• Querying and verifying packages
  
• Installing, upgrading, and removing packages
  
• Performing miscellaneous functions
  
• We will focus on the first two sets of command options in this tutorial. You will find information about the miscellaneous functions in the man pages for RPM.

Pre-requisites

To get the most from the tutorials in this series, you should have a basic knowledge of Linux and a working Linux system on which you can practice the commands covered in this tutorial. Sometimes different versions of a program will format output differently, so your results may not always look exactly like the listings and figures shown here. In particular, much of the output we show is highly dependent on the packages that are already installed on our systems.
