When Linux is up and running, you may want to install or remove disk sets and other software. You can also check that components of a disk set have been properly installed. A few different utilities are available for this task, but the most common is called pkgtool. When you enter the pkgtool command name at the shell prompt, a menu that enables you to install new software, remove existing software, or view installed files in a package appears on-screen. Figure 3.22 shows the pkgtool menu. You can also use the setup utility for these tasks.

Figure 3.22.
The pkgtool utility is one way to install, remove, or examine software on your Linux system.

To view the contents of a package, select View from the main pkgtool menu, and then choose the name of the package from the list presented. Figure 3.23 shows the list of packages. The list should include all the disk set tools you have installed, as well as any additional software installed after the first installation. Selecting a tool name sends pkgtool to check all the files that should be in the software and report its success. Sometimes the list of software in a package can take a while to appear. Be patient! The list pkgtool presents usually has a brief description of the tool and a list of all the files in the installation. Figure 3.24 shows the entry for the base software package.

When you select View from the pkgtool utility, you must choose which package to view.

When the list of files is displayed, you can move through them with the space bar. To leave the list of files, select the Exit option at the bottom of the screen.
