Getting Started Guide 129 CHAPTER 10 Installing New Software OpenLinux includes all the software you need to get started using your Linux system for Internet access, text editing, and so forth. You may quickly find, how- ever, that you want to install other Linux applications that you have obtained, or that are included on the OpenLinux CD-ROMs but that were not installed by default. This chapter describes how Linux software is usually packaged and how to work with those packages. Understanding rpm Software Packages The concept of a software package makes it simple to manage your OpenLinux system. Every software component that is installed on your system is part of a package. OpenLinux includes package management tools to quickly and easily install new software from the Caldera CD-ROM. NOTE: Some software packages do not use the rpm software package format. For those applications, refer to the applica- tion’s documentation to learn about how to install it. Software packages on the Caldera CD-ROM are stored in a format called rpm. Each rpm file (having a file extension .rpm) contains the files that comprise the software, plus additional information about where to install each file, how much disk space the software requires, and how to run any initialization files that the software provides.
