316 Part III . Choosing and Installing a Linux Distribution You generally want to run this command before installing new packages so that you do not download an older version. Run it before checking for upgrades as well. Finding and Installing Packages When looking for new packages to install, you may not always know what package you want. The package database maintained by APT includes package descriptions and other fields that can be searched using the apt-cache utility: # apt-cache search tetris bsdgames a collection of classic textual unix games pytris two-player networked console tetris clone stax collection of puzzle games similar to Tetris Attack. Specifying multiple keywords in a search prevents apt-cache from listing packages that do not contain all of the keywords you specify. This enables you to do very specific searches such as word processor. You can also use this utility to find out more information about a specific package in the repositories: # apt-cache show pytris Package: pytris Priority: optional Section: games Installed-Size: 101 Maintainer: Radovan Garabik Architecture: i386 Version: 0.96 Depends: python (>=2.1), libc6 (>= 2.2.4-4) Filename: pool/main/p/pytris/pytris_0.96_i386.deb Size: 16304 MD5sum: 70eb8ad6f5a8a901a95eb37f7336fc57 Description: two-player networked console tetris clone two-player networked console based tetris clone, written in python, similar to xtet42. To view information about a specific package that is already installed on your system, use dpkg, as discussed later in this chapter. Once you know the name of the package you want to install, use the install method to download it and any packages on which it depends. For example, the ssh package is very useful for remotely accessing systems and is probably one of the first programs that you will want to install: # apt-get install ssh Note Tip
